Chapter 2 Installation 2-1 INTRODUCTION This chapter provides information for the initial inspection and preparation for use of the 37xxxE Vector Network Analyzer. Information for interfacing the 37xxxE to the IEEE-488 General Purpose Interface Bus and reshipment and storage information is also included. 2-2 INITIAL INSPECTION Inspect the shipping container for damage.
PREPARATION FOR USE Option 4, Additional SD Card for Secure Environments 2-4 INSTALLATION The 37xxxE is available with a second Secure Digital memory card (SD Card) for use in secure environments. This allows the VNA to be shipped with the System Software and Factory Cal Data on both the standard and additional SD Cards.
INSTALLATION 2-4 GPIB SETUP GPIB SETUP All functions of the 37xxxE (except power on/off and initialization of the SD Card) can be controlled remotely by an external computer/controller via the IEEE-488.2 GPIB. The information in this section pertains to interface connections and cable requirements for the rear panel GPIB connector. Refer to the Model 37xxxE Programming Manual, Anritsu Part Number 10410-00301, for information about remote operation of the 37xxxE using the GPIB.
SYSTEM GPIB INTERCONNECTION INSTALLATION 2-5 SYSTEM GPIB INTERCONNECTION GPIB Interface to an External Plotter GPIB Addresses 2-6 ETHERNET SETUP AND INTERCONNECTION There are two rear panel GPIB IEEE-488 connectors. The IEEE 488.2 connector used to interface the 37xxxE to an external computer/ controller via a standard GPIB cable. The Dedicated GPIB connector is used to interface to plotters and a second source for multiple source operation via a standard GPIB cable.
INSTALLATION ETHERNET SETUP AND INTERCONNECTION One known inconvenience is the actual assigned IP values do not refresh automatically on the screen. A quick way to do get them refreshed is to manually re-access the Network Utilities Menu, which will then display them correctly. The 37xxxE can be remotely controlled via a network server and an Ethernet connection via the standard RJ45 connector on the rear panel. The 37xxxE software supports the TCP/IP network protocol.

Reflection Measurements The 37xxxE is a self-contained, fully integrated measurement system that includes an optional time domain capability.
NETWORK ANALYZERS, A PRIMER 3-3 NETWORK ANALYZERS NETWORK ANALYZERS We will begin this discussion with a subject familiar to most Anritsu customers: scalar network analysis. After showing comparisons, we will proceed to the fundamentals of network analyzer terminology and techniques. This discussion serves as an introduction to topics presented in greater detail later in this section.
NETWORK ANALYZERS A NETWORK ANALYZER IS A TUNED RECEIVER INTERMEDIATE FREQUENCY (IF) MICROWAVE SIGNAL TUNABLE LOCAL OSCILLATOR • GREATER DYNAMIC RANGE • LESS SENSIVITY TO INTERFERING SIGNALS Figure 3-4. NETWORK ANALYZERS, A PRIMER Vector Network Analyzer Basics The network analyzer is a tuned receiver (Figure 3-4, left). The microwave signal is down converted into the passband of the IF. To measure the phase of this signal, we must have a reference to compare it with.
NETWORK ANALYZERS, A PRIMER REFERENCE SIGNAL TEST SIGNAL PHASE DETECTOR MICROWAVE SOURCE SPLITTER LONGER BY ONE WAVELENGTH LENGTH (360 degrees) Figure 3-8. TEST SIGNAL PHASE DETECTOR MICROWAVE SOURCE SPLITTER SAME PATH LENGTH -BUTWAVELENGTH IS NOW SHORTER 1.1 WAVELENGTHS = 396 degrees MEASURED PHASE Assume that we are making a measurement at 1 GHz and that the difference in path-length between the two signals is exactly 1 wavelength.
NETWORK ANALYZERS NETWORK ANALYZERS, A PRIMER MEASURED PHASE There are two ways of accomplishing this. The most obvious way is to insert a length of line into the reference signal path to make both paths of equal length (Figure 3-11, below). With perfect transmission lines and a perfect splitter, we would then measure a constant phase as we change the frequency. The problem using this approach is that we must change the line length with each measurement setup. +180 REFERENCE SIGNAL +90 0 1.1 1.2 1.
NETWORK ANALYZERS, A PRIMER NETWORK ANALYZERS Network Analyzer Measurements PORT 1 FORWARD REFLECTION Figure 3-14. PORT 2 DUT REVERSE REFLECTION Forward and Reverse Measurements S21 FORWARD TRANSMISSION PORT 1 S11 FORWARD REFLECTION PORT 2 DUT S22 REVERSE REFLECTION Now let us consider measuring the DUT. Consider a two port device; that is, a device with a connector on each end.
NETWORK ANALYZERS There are several ways in which all the information can be displayed on one trace. One method is a polar display (Figure 3-17). The radial parameter (distance from the center) is magnitude. The rotation around the circle is phase. We sometimes use polar displays to view transmission measurements, especially on cascaded devices (devices in series). The transmission result is the addition of the phase and log magnitude (dB) information of each device’s polar display.
NETWORK ANALYZERS, A PRIMER NETWORK ANALYZERS Another important parameter we can measure when phase information is available is group delay. In linear devices, the phase change through the DUT is linear-with-frequency. Thus, doubling the frequency also doubles the phase change. An important measurement, especially for communications system users, is the rate of change-of-phase-vs.-frequency (group delay). If the rate of phase-change-vs.-frequency is not constant, the DUT is nonlinear.

Chapter 6 Data Displays 6-1 6-2 INTRODUCTION This chapter provides discussion and examples of the various types of data displays. DISPLAY MODES AND TYPES The 37xxxE displays measurement data using a “Channel Concept.” This means that each channel can display both a different S-Parameter and a different graph type. As you select each channel, the graph type, scaling, reference delay, S-Parameter, etc., associated with that channel appears on the screen.

You select this display type by choosing “Dual Display” in Menu CM (Appendix A).
DATA DISPLAYS Four Channel Display: Ch 1, 2, 3, 4 DISPLAY MODES AND TYPES From four-to-eight graph types are displayed. In each quadrant, the graph type can be any of the possible choices listed in the GT menu (Appendix A). If you have chosen to display magnitude and phase on a channel, the quadrant displaying that channel is further subdivided as described above. You select this display type by choosing “All Four Channels” in Menu CM. An example of a four-channel display appears in Figure 6-4, below.
DISPLAY MODES AND TYPES Dual Trace Overlay DATA DISPLAYS For rectilinear graph types, two traces can be displayed, one overlaid (superimposed) on the other (Figure 6-5). By menu selection, the two traces can be Channel 1 overlaid on Channel 3 or Channel 2 overlaid on Channel 4. Each trace is in a different color. Channels 1 and 2 are displayed in red, while Channels 3 and 4 are displayed in yellow. CH1:S11 FWD REFL CH3:S21 FWD TRANS LOG MAG. LOG MAG. REF= 0.000 dB REF= 10.000 dB/DIV 2.

When a marker reaches the top of its graticule, it will flip over and its number will appear below the symbol. When markers approach the same frequency, they will overlap. Their number will appear as close to the marker as possible without overlapping. S11 S12 -20.000 dB 1 Z LOGM+P 10.000 dB/DIV 2 .5 .
STATUS DISPLAY DATA DISPLAYS Each channel has two limit lines (four for dual displays), each of which may take on any value. Limit lines are either horizontal lines in rectilinear displays or concentric circles around the origin in Smith and polar displays. Each channel can produce segmented limits. They allow different upper and lower limit values to be set at up to ten segments across the measurement range.
DATA DISPLAYS Measurement Status Sweep Indicator Marker 6-6 DATA DISPLAY CONTROL DATA DISPLAY CONTROL The 37xxxE displays measurement-status messages (in red when appropriate) in the upper-right corner of the graticule (channel) to which they apply. A blue sweep-indicator marker appears at the bottom of each displayed graph-type. It indicates the progress of the current sweep.
DATA DISPLAY CONTROL S-parameter Selection Data Display Update DATA DISPLAYS If you select a new S-parameter using Menu SP (Appendix A), it appears on the then-active channel in the same graph-type in which it was last displayed. The following table shows the displayable S-parameters based on the correction type you have in place. If you attempt to display other S-parameters, an error message appears. In cases when there is no last-displayed S-parameter stored, the display will default as shown.

Chapter 7 Measurement Calibration 7-1 INTRODUCTION This section provides discussion and examples for performing a measurement calibration. It also provides a detailed procedure for calibrating with a sliding termination. 7-2 DISCUSSION Measurements always include a degree of uncertainty due to imperfections in the measurement system. The measured value is always a combination of the actual value plus the systematic measurement errors.
DISCUSSION MEASUREMENT CALIBRATION The use of cables and/or adapters does not effect the final measurement result, if they were in place for the calibration process. The vector error corrections established during the calibration process eliminates cable and/or adapter effects as long as the ports used are stable and exhibit good repeatability. Figure 7-2 shows such a configuration. ADAPTERS PORT 1 PORT 2 Figure 7-2.
MEASUREMENT CALIBRATION DISCUSSION This approach offers two advantages: q It minimizes wear on the more expensive test set and cable connectors q It provides a simple solution to measuring non-insertable devices (e.g., a filter with K female input and output connectors) by merely swapping PEAs after calibration. See Figure 7-4 NOTE In this and other discussions, we will talk about “insertable” and “non-insertable” devices. Insertable devices have an insertable connector pair (i.e.

ERRORS REDUCED BY CALIBRATION · Directivity · Source Match · Load Match · Frequency Sensitivity (Tracking) · Isolation We know that adapters and cables degrade the basic directivity of the system, but these errors are compensated by vector error correction.
MEASUREMENT CALIBRATION DISCUSSION Reflection Only: Corrects for the three error terms associated with an S11 measurement (EDF, ESF, and ERF), an S22 measurement (EDR, ESR, and ERR), or both.

MEASUREMENT CALIBRATION Calibrating for a Measurement CALIBRATING FOR A REFLECTION MEASUREMENT USES THREE STANDARDS: · Short · Open · Termination IDEAL TERMINATIONS · Reflectionless · Perfect Connector · Infinite-Length, Dimensionally Exact, Reflectionless Transmission Line PRACTICAL Zo TERMINATIONS · Broadband Load · Sliding Termination 37xxxE OM DISCUSSION Let us assume that we want to correct for three errors in the reflection measurement: source match, directivity, and tracking.
DISCUSSION BROADBAND LOAD · Easy to Use · Inexpensive · Adequate for Most Applications SLIDING LOAD · Connector · Long Transmission Line · Movable Microwave Load MEASUREMENT CALIBRATION Broadband loads are widely used. An example is the Anritsu 28 Series Termination. These terminations are easy to use as calibration tools, and they are adequate for most applications. Sliding Loads are the traditional vector network analyzer Z0 calibration reference.
MEASUREMENT CALIBRATION Evaluating the Calibration DISCUSSION The 37xxxE provides an accurate representation of complex data. However, it can only provide accuracy to the extent of the supplied calibration data. For this reason, it is necessary to periodically verify the calibration data and the 37xxxE system performance. Calibration verification reveals problems such as a poor contact with one of the calibration components, improper torquing, or a test port out of specification.
DISCUSSION MEASUREMENT CALIBRATION The verification of the kit components is straight forward. The components are first measured with the 37xxxE, then they are compared with the data recorded on the USB drive. If the measured data compares favorably with the recorded data (taking tolerances into consideration), then the system is known to be operating properly and providing accurate data. There is one caution that you need to observe when using Verification Kits.
MEASUREMENT CALIBRATION 7-3 SLIDING TERMINATION SLIDING TERMINATION Sliding terminations (loads) are the traditional Z0 calibration-reference devices for vector network analyzer calibration. When correctly used and perfectly aligned, they can be more accurate than precision fixed loads. However, sliding terminations have a 2 GHz (4 GHz for V-Connector sliding loads) low-frequency limit and must be used with a fixed load for full frequency-range coverage.
SLIDING TERMINATION 7-14 MEASUREMENT CALIBRATION Step 2. Push the outer locking ring towards the gauge to expose the center pin. Step 3. Take the 01-210 Ref Flat from the kit. Step 4. While holding the gauge as shown, press the Ref Flat firmly against the end of the exposed center pin.
MEASUREMENT CALIBRATION Step 5. SLIDING TERMINATION While pressing the Ref Flat against the center pin, check that the pointer aligns with the “0” mark. If it does not, loosen the bezel lockscrew and rotate the bezel to align the pointer with the “0” mark. Tighten the bezel lock screw. NOTE Gently rock the Ref Flat against the center pin to ensure that it is fully depressed and you have accurately set the gauge for zero. 37xxxE OM Step 6.
SLIDING TERMINATION 7-16 MEASUREMENT CALIBRATION Step 9. Remove the flush short by holding its body and unscrewing its connector. Step 10. Install the gauge onto the end of the sliding termination. Step 11. If the COARSE SET adjustment—which has been set at the factory—has not moved, the inner dial on the gauge will read “0.” If it doesn’t, perform the Coarse Set Adjustment in Step 15. Step 12. Place the sliding termination, with the gauge attached, on the bench top.
MEASUREMENT CALIBRATION SLIDING TERMINATION Step 13. Loosen the FINE LOCK ring and turn the FINE ADJ ring to position the gauge pointer 2-3 small divisions on the “–” side of zero. Step 14. Turn the FINE LOCK ring clockwise to both tighten the adjustment and place the pointer exactly to “0.” The Sliding Termination is now ready to use. NOTES Ensure that the inner dial reads “0.” The following step is not normally necessary.
SLIDING TERMINATION 7-18 MEASUREMENT CALIBRATION Step 17. Remove the 01-223 Female Adapter (“F ADAPTER FOR PIN GAUGE”) from the kit. Step 18. Install the female adapter over the center pin and screw it into the locking ring, and tighten the outer ring until it is snug against the housing. Step 19. Inspect the end of the adapter, you should see no more than two exposed threads. If so, repeat Steps 7 through 10. Step 20.
MEASUREMENT CALIBRATION 7-4 SOLT CALIBRATION Calibration Procedure SOLT CALIBRATION The SOLT calibration for the 37xxxE Vector Network Analyzer system uses a Short, Open, Load, and a Thru line connection to categorize the inherent errors in the measurement system. These errors include those caused by connectors as well as internal system errors such as RF leakage, IF leakage, and component interaction. For maximum accuracy, install the capacitive coefficients (for the open device) using Menu U3.
SOLT CALIBRATION MEASUREMENT CALIBRATION Step 3. MENU C11A CHANGE CAL METHOD AND LINE TYPE When menu C11A (left) appears, move the cursor to the following: a.

REFLECTION PAIRING MIXED b. Move the cursor to REFLECTION PARING and press the Enter key.
LRL/LRM CALIBRATION 7-7 LRL/LRM CALIBRATION MEASUREMENT CALIBRATION The LRL/LRM (line-reflect-line/line-reflect-match) calibration* feature provides an enhanced capability for error compensation when making measurements in coaxial, microstrip and waveguide transmission media. Instead of using the standard Open, Short, and Load, the LRL/LRM calibration method uses two lines and a reflection or match.
MEASUREMENT CALIBRATION LRL/LRM Calibration (Microstrip) LRL/LRM CALIBRATION Microstrip is a dispersive media. The 37xxxE applies dispersion compensation during calibration for microstrip measurements.

LRL/LRM CALIBRATION LRL/LRM Calibration (Coaxial) MEASUREMENT CALIBRATION An LRL cal kit is necessary to perform the coaxial calibration. Calibration kits for GPC-7 are available from Maury Microwave and Agilent. Two line lengths are used as the impedance standard. The calibration frequency range is limited by the difference in the lengths of the two lines. Their length must be different by approximately 90 degrees at the mid-band frequency.
MEASUREMENT CALIBRATION LRL/LRM CALIBRATION Consideration must also be given to selecting the breakpoint frequency. Divide the frequency range to satisfy the 9:1 rule for any given pair of lines. The range is thus divided by the frequency breakpoint into the intervals [f1, f2] and [f2, f3]. Based on these intervals, next determine the appropriate length differences; the longer difference is associated with the lower interval [f1, f2].
TRM CALIBRATION LRL/LRM Calibration (Waveguide) MEASUREMENT CALIBRATION The waveguide procedure is very similar to the coaxial and microstrip procedures already described. Step 1. MENU C3F CONFIRM CALIBRATION PARAMETERS The only difference is with menu C3F (left). For a waveguide calibration, move the cursor to WAVEGUIDE CUTOFF FREQ and press Enter. This action calls menu C15B, which lets you enter the waveguide cutoff frequency. After doing so, you are returned to menu C3F.
MEASUREMENT CALIBRATION 7-9 MERGE CAL FILES APPLICATION MERGE CAL FILES APPLICATION The Merge Cal Files application allows the user to combine two or more calibrations that were performed on the VNA, but having differing frequency ranges. This is of particular importance when a wide band RF calibration cannot be performed because wide band calibration components, such as loads and shorts, are not available. Such a case exists when using Anritsu’s 37x97E wideband VNAs.

Chapter 8 Measurements 8-1 8-2 INTRODUCTION This section discusses typical measurements that can be made with the Model 37xxxE Vector Network Analyzer. TRANSMISSION AND REFLECTION This discussion provides information on general measurement considerations and transmission and reflection measurements using the 37xxxE. Setup and Calibration To get started, apply power to the system. After turning on the power, allow the system to warm up for at least 60 minutes before operation.
TRANSMISSION AND REFLECTION MEASUREMENTS Install the calibration kit devices to the test ports as instructed by the U3 menu. Both the capacitance coefficients for the Open and the offset lengths for the Open and Short can be modified or defined. Selecting the Begin Cal key starts the calibration process. The Calibration menus step you through the calibration process, as follows: Select the type of calibration desired. Select the frequency range of calibration.
MEASUREMENTS TRANSMISSION AND REFLECTION Up to six markers are available. Using the Marker Menu, you can set the frequency of each one, you can set each one in the delta marker mode, and you can set each marker’s level to maximum or minimum. In some cases—such as in a production environment—limit lines are desirable. Options within the menu called up using the Limits key, provide for one or two flat, sloped, or single-point-segmented limit lines for each channel.
TRANSMISSION AND REFLECTION MEASUREMENTS To label the output, select Setup Output Headers in the Output Menu or press the Device ID key. On the output to the printer, plotter, or storage drive. a menu then appears that lets you specify the device name/serial number, the date, the operator’s name, and user comments (Figure 8-2).
MEASUREMENTS TRANSMISSION AND REFLECTION Finally, you can enhance the measurement data by reducing the IF bandwidth and using averaging and/or smoothing.

We call this point the reference plane.
MEASUREMENTS TRANSMISSION AND REFLECTION Let us assume both that our system is already calibrated and that we have equalized the system for the test port in use. We would then 1. Connect the Short: A Short always appears as a dot at the left-most edge of the Smith chart’s horizontal axis. 2. Connect a Termination: Now you will see another dot located at the center (1+j0) of the chart (this assumes a 50-ohm load). 3. Connect the Open: An Open appears as an arc on the chart’s right edge.
TRANSMISSION AND REFLECTION MEASUREMENTS Now let’s perform a reflection measurement on a 20 dB attenuator over the 1 to 18 GHz range. We need to determine the setup, calibration, and measurement requirements. A known good starting point is to reset with Default Program parameters. Since our measurement lies between 1 and 18 GHz, set the Start and Stop frequencies using the Sweep Setup menu that appears on the display following system reset.
MEASUREMENTS TRANSMISSION AND REFLECTION Now let us perform a transmission measurement on the same 20 dB attenuator over the same frequency range. We will follow the same steps as before, but this time we will use additional features. Once again, reset the system using the Default Program key. In this calibration we will select the N-Discrete Frequencies menu option and step all frequencies in increments of 50 MHz.
LOW LEVEL AND GAIN 8-3 LOW LEVEL AND GAIN MEASUREMENTS This discussion provides methods and techniques for making gain and low-signal-level measurements. It is divided into 37xxxE system considerations and test device considerations. 37xxxE System Considerations The 37xxxE system is limited in its ability to test low-signal levels by its dynamic range and signal-to-noise-power ratio.
MEASUREMENTS LOW LEVEL AND GAIN The detected signal is the vector sum of the desired signals, the noise signals, and the leakage signals. These signals introduce an error or uncertainty (Figure 8-8). D E T E C T E D O U T P U T S IG N A L U N C E R T A IN T Y RNAY M G A II N O IS E S IG N A L L E A K A G E O R F A L S E S IG N A L M E A S U R E D S IG N A L A C T U A L S IG N A L P H A S E E R R O R R E A L Figure 8-8.

MEASUREMENTS LOW LEVEL AND GAIN The most difficult types of measurements are those that exercise the full dynamic range of the 37xxxE, such as filters (Figure 8-11. Filter measurements are examples of where one must observe both low-insertion loss (in the passband) and high attenuation (in the stop band). B A N D P A S S F IL T E R S 2 1 d B < 1 d B P A S S B A N D 0 d B > 5 0 d B S T O P B A N D F R E Q U E N C Y Figure 8-11.
LOW LEVEL AND GAIN MEASUREMENTS Averaging is another way to improve accuracy. The improvement is proportional to the square root of the number of averages. Two types of averaging are supported: Sweep-by-sweep and point-by-point. Point-by-point averaging works by collecting multiple measurements while at each frequency point and then averaging them together.
MEASUREMENTS LOW LEVEL AND GAIN Test Device (DUT) Considerations In order to test a device, the required input RF level and the expected device output RF level must be determined. The RF level at Port 1 must be set for the device input RF power level required. Attenuation can be added in steps of 10 dB up to 70 dB using the built-in source attenuator. Amplification can be added by removing the front panel loop and adding an external amplifier.
LOW LEVEL AND GAIN MEASUREMENTS The 37xxxE uses enhancements in the calibration to ensure a wide dynamic range. It automatically selects 1 kHz IF bandwidth and varies the number of averages with the calibration device. Terminations require the most averages. If desired, the Video IF bandwidth and number of averages can be specified for the calibration measurements. Using 100 averages (Avg = 100) appears to be sufficient for most measurements.
MEASUREMENTS LOW LEVEL AND GAIN Wide Dynamic Range Device - Filter Since you do both low-insertion-loss and high- attenuation measurements simultaneously, use the maximum RF signal level and no attenuation. Selecting the 1 kHz Video IF BW setting and 100 averages will likely suffice for this kind of measurement (Figure 8-13).

GROUP DELAY 8-4 GROUP DELAY MEASUREMENTS Group delay is the measure of transit time through a device at a particular frequency. Ideally, we want to measure a constant—or relatively constant—transit time over frequency. The top waveform shown in Figure 8-14 is measured at one frequency. The bottom waveform is identical to the first, simply delayed in time. M A G N IT U D E t Figure 8-14.
MEASUREMENTS GROUP DELAY When designing components it is important to measure group delay so that you can compensate for any distortion caused by the component. You may be able to tune the device so as to optimize the performance of group delay over the frequency range of interest. Outside of the specified frequency range, the group delay may or may not be linear. So how is group delay measured? Signals travel too fast to enable measuring the input and output times of each frequency component.
GROUP DELAY MEASUREMENTS Let us take a look at a group delay measurement made on the Anritsu 37347E Vector Network Analyzer. Group delay, as a measurement option, can be found in the Graph Type menu. After selecting the option, the VNA displays the data in a time-vs-frequency graph, or to be more exact, a group-delay-vs-frequency graph (Figure 8-17).

MEASUREMENTS GROUP DELAY The aperture defaults to the smallest setting for the frequency range and number of data points selected. This value is displayed in the Set Scale key menu when measuring group delay (Figure 8-19). S 2 1 F O R W A R D T R A N S M IS S IO N G R O U P D E L A Y R E F = 1 .0 0 0 n S 3 .0 0 0 0 Figure 8-19.

ACTIVE DEVICE 8-5 ACTIVE DEVICE MEASUREMENTS Active devices are key components in microwave systems. The measurements that are made on active devices are similar to those made on passive devices. Active devices come in many shapes and sizes. In most cases we are going to have to develop a fixture in which to mount the device. Active devices require bias voltages, and in many cases they are easily damaged. High gain amplifiers may saturate with input signals of –50 dBm.
MEASUREMENTS ACTIVE DEVICE Test fixtures are necessary for mounting the device so that it can be measured in our coaxial (or waveguide) measuring system (Figure 8-21). Figure 8-21. Active Device Test Fixture Now we have an interesting situation. While we can measure the performance at the connector—which is the calibration plane—what we really want to know is how our device performs (Figure 8-22). F E T G P C -7 G P C -7 S S Figure 8-22.
ACTIVE DEVICE MEASUREMENTS 5 0 O H M L IN E G P C -7 D U T N O Figure 8-23. L O S S , R E F L E C T IO N L E S S Simple Example of De-Embedding In some cases—depending on the fixture or the device being measured—this is satisfactory. But when it is not, we need to employ other techniques.
MEASUREMENTS ACTIVE DEVICE In the discussion on calibration we saw that the calibration components establish the reference plane and determine the quality of the measurement. If we have a good Open, Short and Z0 load to place at the end of a microstrip line, we can calibrate the system at the point of measurement. Figure 8-25 shows some of the special test-fixture calibration standards that are available. Figure 8-25.
ACTIVE DEVICE MEASUREMENTS CAUTION You should turn off or disconnect the bias supplies during the calibration, since you are using a Short as the calibration standard. It is also possible to use three known impedances. For instance, a varactor with three voltages applied (Figure 8-27).

Three Known Impedances The second approach is to model the fixture.
MEASUREMENTS 8-6 MULTIPLE SOURCE CONTROL MULTIPLE SOURCE CONTROL The Multiple Source Control mode permits independent control of the 37xxxE source, receiver, and an external Anritsu synthesizer (67xxB, 68xxxB, MG369xx), without the need of an external controller (Figure 8-28). 1. Remove a1 loop on the front panel (Opt. 15 only). 2. Set up equipment as shown. 3. Normalize the data trace with the standard mixer installed. 4.

ADAPTER REMOVAL 8-7 ADAPTER REMOVAL MEASUREMENTS Using adapters in VNA measurement applications can introduce complex errors that add to measurement uncertainty. The VNA Adapter Removal procedure provides for adapter compensation. This on-screen, menu-driven procedure allows the use of a through-line device or adapter with different connector types (non-insertables) on either end to be used for measurement calibration. The electrical effects are subsequently compensated for.

MEASUREMENTS 8-8 GAIN COMPRESSION GAIN COMPRESSION There are a number of ways to measure Gain Compression. With a VNA two approaches are possible: Swept Frequency Gain Compression (SFGC) and Swept Power Gain Compression (SPGC). The 37xxxE offers a very straightforward approach to each of these measurements.

Correction Factor (%) Error (dB) 1 0.043 3 0.128 5 0.212 10 0.414 It is desirable to set the power control at or near the minimum (this varies from −20 to−30 dB, depending upon model) when establishing P, as this provides the full ALC range for a power sweep. The vector error correction available in VNAs is dependent upon ratioed S-parameter measurements.

MEASUREMENTS 8-11 OPTICAL APPLICATION OPTICAL APPLICATION Optical applications are divided into two measurement categories, electro-optical (E/O) and opto-electrical (O/E). E/O measurements can be performed with the 372xxE/373xxE series VNAs using the built-in E/O measurement application. On-screen menu-driven procedures guide you through the set-up and calibration required for E/O measurements of optical modulators such as bandwidth, flatness, and group delay.
OPTICAL APPLICATION MEASUREMENTS E/O Measurement Procedure The following procedure will explain ways of using the MN4765A photo-diode to make an E/O measurement of a modulator DUT. The same set up can be used for a user characterized photo-diode as well. MENU APPL Step 1. Set-up the measurement as shown in Figure 8-33. Step 2. Perform a 12-term calibration on the VNA over the frequency range of interest with reference planes at the DUT input and the photo-diode output.
MEASUREMENTS OPTICAL APPLICATION This brings up menu DE3 (top left). MENU DE3 E/O MEASUREMENT Step 7. ORIGINAL CAL FILE WITH FWD TRANS CORRECTION READ CAL FILE FROM SD CARD READ CAL FILE FROM USB DRIVE PRESS TO SELECT This bring up menu DSK2 (middle left). Step 8. Select the calibration file and press Enter. Step 9. Read the S2P file (characterization data file) for the photo-diode transfer standard. This will de-embed the photo-diode for an E/O measurement (menu DE3A, bottom left).
OPTICAL APPLICATION MEASUREMENTS Step 10. Press Save/Recall and save this de-embedded calibration to the SD Card or USB drive. NOTE Observe that the S11 graph displays the electrical return loss (port match) of the modulator and S21 represents the transfer function of the modulator. The bandwidth of the modulator can be calculated from the S21 data by setting the delta markers or using the marker search function to find the 3 dB change in magnitude.
MEASUREMENTS OPTICAL APPLICATION Step 1. Set-up the measurement as shown in Figure 8-36, previous page. Step 2. Perform a 12-term calibration on the VNA over the frequency range of interest with reference planes at the modulator input and the photo-receiver DUT output. (Refer to section 7-4 for the 12-term calibration steps.) Step 3. Press Save/Recall to save the calibration and set up to the SD Card or USB drive. Step 4. Press the Appl key to display the applications menu (left). Step 5.
OPTICAL APPLICATION MEASUREMENTS The measurement of the photo-receiver DUT relies on a characterized modulator standard. If a characterized modulator is not available, an S2P file can be created by using a characterized photo-diode and de-embedding it from the 12-term calibration performed in Step 2.

Chapter 9 Time Domain 9-1 9-2 INTRODUCTION This chapter describes the optional Time Domain feature. TIME DOMAIN MEASUREMENTS The Option 2, Time Domain feature provides a useful measurement tool for determining the location of impedance discontinuities. Some typical applications are identifying and analyzing circuit elements, isolating and analyzing a desired response, locating faults in cables, and measuring antennas.
TIME DOMAIN MEASUREMENTS TIME DOMAIN The lowpass impulse response displays the location of discontinuities as well as information useful in determining the impedance (R, L, or C) of each discontinuity. The impulse response is a peak that goes positive for R>Z0 and negative for R
TIME DOMAIN TIME DOMAIN MEASUREMENTS The lowpass step response displays the location of discontinuities as well as information useful in determining the impedance (R, L, or C) of each discontinuity. If you are familiar with time-domain reflectometry (TDR) you may feel more comfortable with step response, as the displays are similar. The lowpass step response for a resistive impedance is a positive level shift for R>Z0 and a negative level shift for R
TIME DOMAIN MEASUREMENTS TIME DOMAIN Use the bandpass-impulse response to show the location of a discontinuity in time or distance, as indicated by changes in its magnitude. Unlike the lowpass mode, no information as to the type of the discontinuity is available. A typical use for this mode is to measure devices—such as, filters, waveguide, high-pass networks, bandpass networks—where a low-frequency response is not available.

TIME DOMAIN 9-4 WINDOWING Windowing is a frequency filter that we apply to the frequency-domain data when we convert it to time-domain data. This filtering rolls off the abrupt transition at F1 and F2. This effectively produces a timedomain response with lower sidelobes. Windowing allows a limited degree of control over the pulse shape, trading off ringing (sidelobes) for pulse width (Figure 9-15).
GATING 9-5 TIME DOMAIN GATING G A T IN G G A T E D IS T A N C E G A T E A P P L IE D Figure 9-17. Gating Gating is a time filter that allows for removing unwanted time-domain responses by gating the desired response. We can view the isolated response in both time domain—and in the frequency domain—using the FREQUENCY WITH TIME GATE selection (Figure 9-17). There are four different gate shapes available: MINIMUM, NOMINAL, WIDE, and MAXIMUM (Figure 9-18). The 37xxxE defaults to the NOMINAL gate.
TIME DOMAIN GATING An informational message will be displayed in the data area when the window or gate shape reset in this way. The message will last two sweeps and will say: “GATE SHAPE ADJUSTED” or “WINDOW SHAPE ADJUSTED” depending on which was changed by the software. Figure 9-18A. Minimum Gate Shape Figure 9-18B. Nominal Gate Shape Figure 9-18C. Wide Gate Shape Figure 9-18D.
ANTI-GATING 9-6 9-7 TIME DOMAIN ANTI-GATING Anti-gating is the opposite of gating. Whereby, gating provides for removing all but the desired response, anti-gating displays all but the desired response. To provide anti-gating, gate in the normal manner, except use a minus value for the SPAN width. EXAMPLES, GATING AND ANTI-GATING Examples of anti-gating are shown in Figures 9-19 through 9-24.

Chapter 10 AutoCal 10-1 10-2 INTRODUCTION DESCRIPTION This chapter provides a general description of the AutoCal calibrators, including specifications, setup, and the use of the associated software and on-line documentation. This series has three models, as shown below. Throughout this manual, the term AutoCal will refer to the series. Individual models will be referred to by model number. Figure 10-1 shows the AutoCal module and all of its attaching parts. Model Switch Freq.
CALIBRATIONS 10-3 CALIBRATIONS AUTOCAL Four types of calibration can be performed using AutoCal: One-Port: S11 1-Port and S22 1-Port are 1-port calibrations performed on the indicated port of the VNA and are equivalent to the traditional Open-Short-Load calibrations. Full 2-Port: This type is equivalent to the traditional Open-Short-Load-Thru (OSLT) calibration. Thru Update: This type is a new form of calibration which is used to update an existing 12-term calibration in the VNA.
AUTOCAL DEFINITIONS Isolation: For certain measurements which require accurate S21 or S12 readings for very small values of those parameters, an isolation step is required to characterize the leakage of the VNA and test setup. The isolation step can be performed automatically as part of a “Full 2-Port” calibration when using the mechanical module. The isolation step requires a manual operation for the electronic module.
PHYSICAL SETUP 10-5 PHYSICAL SETUP AUTOCAL See Figure 10-2 for an illustration of the connections necessary to perform an automatic calibration using the AutoCal module. Note that the connection is very simple. Different power cable connectors are used with the mechanical modules and the electronic modules to prevent connecting the wrong power supply in error. There is no on-off switch. When power is connected to the AutoCal module, the LED labeled POWER should come on immediately.
AUTOCAL 10-6 CHARACTERIZATION FILES CHARACTERIZATION FILES . Before performing an AutoCal on a 37xxxE, the Characterization File for the AutoCal Module has to be loaded. This file may be recalled from the USB drive accompanying the Module. It may also be recalled from one generated using the user's specialized manual calibration. - Channels Measurement Display Enhancement Insert the AutoCal Module Characterization USB drive into the USB port.
