4. Calibration 4 Calibration This chapter describes the calibration processes that should be used with the Agilent E5070B/E5071B.
Calibration Measurement Errors and their Characteristics Measurement Errors and their Characteristics It is important to understand the factors contributing to measurement errors in order to determine the appropriate measures that should be taken to improve accuracy.
Calibration Measurement Errors and their Characteristics Systematic Errors Systematic errors are caused by imperfections in the measuring instrument and the test setup (cables, connectors, fixtures, etc.). Assuming that these errors are repeatable (i.e., predictable) and their characteristics do not change over time, it is possible to eliminate them mathematically at the time of measurement by determining the characteristics of these errors through calibration.
Calibration Measurement Errors and their Characteristics Directivity error (Ed) Directivity errors are caused by the fact that, in a reflection measurement, signals other than the reflection signal from the DUT are received by receiver T1 (Figure 4-1) through the directivity coupler. When a certain port is a stimulus port, this error can be defined as a constant value for each stimulus port because the state of the termination at the other ports does not change.
Calibration Measurement Errors and their Characteristics Source match error (Es) A source match error is caused when the reflection signal of the DUT reflects at the signal source and enters the DUT again. When a certain port is a stimulus port, this error can be defined as a constant value for each stimulus port because the state of the signal source switch does not change. The number of source match errors in the E5070B/E5071B is equivalent to the number of stimulus ports you use.
Calibration Measurement Errors and their Characteristics Transmission tracking error (Et) A transmission tracking error is caused by the difference in frequency response between the test receiver of a response port and the reference receiver of a stimulus port in transmission measurements. When a certain port is a stimulus port, a transmission tracking error is defined for each of the other ports.
Calibration Calibration Types and Characteristics Calibration Types and Characteristics Table 4-1 shows the different types of calibrations and the features of each method.

Calibration Selecting Calibration Kit Selecting Calibration Kit Before executing calibration, you need to select a calibration kit. If you use a calibration kit other than a predefined one, you need to define it. If the connector type of the standard of the calibration kit you use has polarity (the distinction between male and female), you need to change the standard class definition of the calibration kit depending on the standard you actually use.

Calibration Calibration between Ports of Different Connector Types Calibration between Ports of Different Connector Types When you perform calibration between ports of different connector types, you need to use a different calibration kit for each test port. In addition, for transmission measurement between 2 ports, you need to use adapters suitable for the connector types of both ports. For example, in order to perform full 2-port calibration between port 1 of an N-type connector and port 2 of a 3.
Calibration Calibration between Ports of Different Connector Types Operating procedure NOTE This VBA macro changes the definition of the label of calibration kit 10 (calibration kit corresponding to the lowest softkey) temporarily, performs calibration, and restores the previous definition after completing calibration. Therefore, if the VBA macro is aborted for some reason, the definition of calibration kit 10’s label may be lost.

FWD Port 1 of the adapter (port 1 of the 2-port Touchstone file) is connected to the test port of the smaller port number of the E5070B/E5071B. RVS Port 2 of the adapter (port 2 of the 2-port Touchstone file) is connected to the test port of the smaller port number of the E5070B/E5071B.
Calibration Calibration between Ports of Different Connector Types based on the setting in “4. Setting Calibration Kit” on page 157 appears (Figure 4-39). Figure 4-39 Display of calibration kit setting for adapter calibration mode The calibration procedure in the adapter calibration mode is the same as that in the normal calibration except that the standard connected for each calibration data measurement differs.
Calibration Adapter Characterization Adapter Characterization To perform calibration between ports of different connector types, you have to obtain the characteristics of the adapter for use in transmission measurement in advance. The adapter characterization function lets you obtain the adapter’s characteristics (S-parameters) and save them to a 2-port Touchstone file. Use the following VBA macro to execute the adapter characterization.
Calibration Adapter Characterization Concept Adapter characterization is a function that calculates the S-parameters of an adapter based on 3 measurement results obtained by using open/short/load standards connected to the test port, via the adapter, for which 1-port calibration has been performed. This VBA macro uses test port 1 for this measurement. The S-parameters of the adapter can be calculated from the above 3 measurement results.
Calibration Adapter Characterization How to execute adapter characterization 1. Setting Stimulus Conditions Set the stimulus conditions of the channel for which you will execute the adapter characterization. For information on the setting procedure, see Chapter 3, “Setting Measurement Conditions.” 2. Performing Calibration Perform 1-port calibration for test port 1 and test port 2 in the channel for which the stimulus condition has been set.
Calibration Adapter Characterization 5. Setting Adapter Characterization Step 1. Press Setup (3 in Figure 4-41). The Setup dialog box shown in Figure 4-42 appears. Figure 4-42 Setup dialog box Step 2. Make the setting of the calibration kit for the adapter that is connected to test port 1 of the E5070B/E5071B in Cal Kit 1 (1 in Figure 4-42). Step 3. Make the setting of the calibration kit for the adapter that is connected to test port 2 of the E5070B/E5071B in Cal Kit 2 (2 in Figure 4-42).
Calibration Adapter Characterization 6. Measuring Data Measure data when each standard is connected. Step 1. Connect the adapter to test port 1 of the E5070B/E5071B. Step 2. According to the setting of Cal Kit 1, connect each standard to the adapter and then press the corresponding button (4 in Figure 4-41). When the data measurement is complete, the button turns yellow. When you calculate the S-parameters using measurement data in one direction only, the data measurement is complete here. Step 3.
Calibration Adapter Characterization Execution procedure of characterization for test fixture using probe The adapter characterization function also lets you obtain the characteristics of a test fixture that is inserted between the instrument and a DUT that cannot be connected directly to the instrument. In this case, a probe is used, and the obtained characteristics are saved to a 2-port Touchstone file.
Calibration Adapter Characterization 6. Measuring Data Step 1. Connect the probe to the end of the test fixture on the DUT side. Step 2. Depending on the setting of Cal Kit 1, connect each standard to the connector side of the test fixture and then press the corresponding button (4 in Figure 4-41). When the data measurement is complete, the button turns yellow. 7. Saving to file Press the Save button (6 in Figure 4-41) to save the calculated S-parameters to a 2-port Touchstone file. 8.
Calibration Adapter Removal-Insertion Adapter Removal-Insertion About Adapter Removal Adapter removal is a technique used to remove any adapter characteristics form the calibration plane. Usually, 2-port network analyzers removes adapter characteristics by performing two sets of full 2-port calibration as shown below. Figure 4-43 Adapter removal 4.
Calibration Adapter Removal-Insertion However, this method is not suitable for a multi-port network analyzer because it will require as many sets of full 2-port calibration as twice the number of port combinations. Hence, E5070B/E5071B uses the following adapter removal process to remove adapter characteristics. 1. Perform calibration with the adapter in use. 2. Remove the adapter from the port and measure Open, Short and Load values to determine the adapter’s characteristics. 3.
Calibration Adapter Removal-Insertion About Adapter Insertion This above described method also makes it possible to add adapter characteristics to a port with full n-port calibration. This allows you to make a measurement with the adapter. E5070B/E5071B uses the following adapter insertion process to insert adapter characteristics. 1. Perform calibration without the adapter in use. 2. Insert the adapter to the port and measure Open, Short and Load values to determine the adapter’s characteristics. 3.
Calibration Adapter Removal-Insertion Procedure for Adapter Removal / Insertion The s-parameter of a reciprocal adapter can be determined when the following data is available. • Open, Short, and Load measurements. • Actual values derived from the CalKit definitions. • An approximate length of the adapter. • Nature of the intended operation : removal or insertion. Once the s-parameter has been determined, run de-embedding and update the error coefficients.

Calibration Specifying Different Standard for Each Frequency Notes on how frequency ranges are dealt when using subclasses By using several subclasses, you can set a different standard for each frequency, but note the following on frequency ranges. The following table shows possible cases and whether calibration is possible.
Calibration Specifying Different Standard for Each Frequency Example 4-2 When frequency ranges specified with subclasses do not cover a part of a measurement frequency range For a measurement frequency range (1 GHz - 8 GHz), if you execute calibration with a standard of subclass 1 (1 GHz-5 GHz) and then with a standard of subclass 2 (6 GHz-8 GHz), Done is not available for the undefined portion (5 GHz-6 GHz).
Calibration Specifying Different Standard for Each Frequency Example 4-4 When a part of a frequency range specified with a subclass lies outside the measurement frequency range For a measurement frequency range (1 GHz - 6 GHz), if you define a standard of subclass 1 (1 GHz - 5 GHz) and a standard of subclass 2 (5 GHz-8 GHz), a part of subclass 2 (6 GHz-8 GHz) lies outside the measurement frequency range, but the other part (5 GHz-6 GHz) lies within it, so calibration is possible.
Calibration Power Calibration Power Calibration The E5070B/E5071B has a calibration feature for power level output that uses the a power meter (power calibration). The power calibration function outputs a stimulus signal with a more accurate power level (closer to the set value) by measuring calibration data (power level) in advance with the power meter and sensor. Then this function performs error correction of the power level by using the calibration data.
Calibration Power Calibration Preparing power meter and sensor To execute power calibration, you need to prepare the power meter and power sensor used to acquire power calibration data. Table 4-9 shows available power meters and recommended power sensors for power calibration.

Calibration Vector-Mixer Calibration Vector-Mixer Calibration The E5070B/E5071B has a vector-mixer calibration function for use in measuring frequency conversion devices. The vector-mixer calibration allows you to measure the magnitude, phase and group delay of the mixer’s conversion loss by using in combination calibration standards (OPEN/SHORT/LOAD) and calibration mixer with an IF filter, as well as the network de-embedding function incorporated in the E5070B/E5071B.
Calibration Vector-Mixer Calibration Figure 4-65 Overview of vector-mixer calibration As shown in Figure 4-65, the vector-mixer calibration requires the characteristics data for the calibration mixer with IF filter. Measured mixer A measured mixer (DUT) signifies an unknown target mixer of measurement. However, a measured mixer meeting the requirements for a calibration mixer can be used as a calibration mixer.

The signals measured at the test port include the reflection signal from the mixer’s RF port, the IF signal (IF+) converted by the mixer and then reflected by the IF filter, and the IF signal (IF-) passing through the IF filer and then reflected by the calibration standard.
Calibration Vector-Mixer Calibration How to execute characterization of calibration mixer 1. Setting Stimulus Conditions Set the stimulus conditions for the channel you want to calibrate. For the necessary steps, refer to “Setting Stimulus Conditions” on page 70. You must also set the external signal source in advance. For the necessary steps, refer to “2. Setting External Signal Source” on page 318. 2.
Calibration Vector-Mixer Calibration 4. Setting IF Frequency Select IF frequency from RF+LO, RF-LO and LO-RF (2 in Figure 4-67), depending on the IF frequency of the calibration mixer. NOTE The number displayed in the Vector Mixer Characterization macro is the frequency set in the E5070B/E5071B and read from it. You must also set the minimum IF frequency at move than 0 kHz. IF BW must be set to much smaller value than IF frequency. 5. Selecting a Calibration Kit Select a calibration kit (3 in Figure 4-67).
Calibration Vector-Mixer Calibration measured mixer. In vector-mixer calibration, where the up/down conversion method is used, the power of the LO signal is distributed to the calibration mixer and the measured mixer through the power splitter. During a characteristics evaluation of the calibration mixer, the LO power level used by the drive of the calibration mixer must be equal to the LO power level with the measured mixer connected.

9. Analysis in Time Domain (Option 010) 9 Analysis in Time Domain (Option 010) This chapter describes how to deal with responses in the time domain by using the time domain function (Option 010).
Analysis in Time Domain (Option 010) Overview Overview Overview of time domain measurement The E5070B/E5071B Option 010 provides the time domain function, which is used to mathematically transform waveforms in the frequency domain that can be measured with a general network analyzer to waveforms in the time domain. Figure 9-1 shows waveforms in the frequency domain and in the time domain when using the same cable.
Analysis in Time Domain (Option 010) Overview Time domain function of E5070B/E5071B The time domain function of the E5070B/E5071B is divided into the following two types of functions. You can use them at the same time. • Transformation function Transforms measurement data in the frequency domain to data in the time domain. For more information, refer to “Transformation to time domain” on page 336. • Gating function Deletes unnecessary data in the time domain from original data in the time domain.
Analysis in Time Domain (Option 010) Transformation to time domain Transformation to time domain The transformation function lets you transform a response in the frequency domain to the corresponding response in the time domain. Measurement flow Table 9-1 shows the measurement flow of this transformation. Table 9-1 Flow of transformation to time domain Item Description “Selecting a type” on page 337 Selects the transformation type from the following.
Analysis in Time Domain (Option 010) Transformation to time domain Selecting a type There are two types of transformation to the time domain: band pass and low pass. The appropriate transformation type depends on the DUT. Comparison between band pass mode and low pass mode Item Appropriate DUT Input signal Band pass DUTs that do not operate with dc current such as band pass filters. You can simulate the response to the impulse signal.
Analysis in Time Domain (Option 010) Transformation to time domain Impulse signal and step signal The E5070B/E5071B lets you simulate the response from the DUT to two types of signals: impulse signal and step signal. The impulse signal is a pulse-shape signal in which the voltage rises from 0 to a certain value and returns to 0 again. The pulse width depends on the frequency sweep range. The step signal is a signal in which the voltage rises from 0 to a certain value.
Analysis in Time Domain (Option 010) Transformation to time domain Setting the window Because the E5070B/E5071B transforms data within a finite frequency domain to data in the time domain, an unnatural change of data at the end points within the frequency domain occurs. For this reason, the following phenomena occur. • Width of impulse signal and rise time of step signal A time width occurs in the impulse signal and a rise time occurs in the step signal.
Analysis in Time Domain (Option 010) Transformation to time domain Operation Step 1. Press (or ) and which you want to set the window. Step 2. Press (or ) to activate a trace for and then press Transform to display the “Transform” menu. Step 3. Press Window and then select a window type. NOTE Softkey Function Maximum Sets the window type to maximum. β of the Kaiser Bessel function is set to 13. Normal Sets the window type to normal. β of the Kaiser Bessel function is set to 6.
Analysis in Time Domain (Option 010) Transformation to time domain Effect of frequency sweep range on response resolution Figure 9-3 shows an example when measuring the same cable while changing the sweep span. When measured in a narrower sweep range, the overlap between two peaks is larger than when measured in a wider sweep range. By performing measurement in a wider sweep range, adjacent peaks can be clearly separated, which means that the response resolution is smaller.
Analysis in Time Domain (Option 010) Transformation to time domain Effect of the window function on the response resolution Lowering the sidelobe level with the window function elongates the width of the impulse signal and the rise time of the step signal.
Analysis in Time Domain (Option 010) Transformation to time domain Measurement range In the time domain function, the measurement range means the range within which the response can be measured without repetition. The repetition of the response occurs because measurement in the frequency domain is performed discretely instead of continuously. The measurement range is inversely proportional to the frequency difference between adjacent measurement points.
Analysis in Time Domain (Option 010) Transformation to time domain resolution and the measurement range.
Analysis in Time Domain (Option 010) Transformation to time domain Setting display range The E5070B/E5071B has the following limitations on the display range you can set. Lower limit − T span *1 Upper limit T span *1 The number of response points displayed on the graph is the same as the number of points regardless of the response resolution. Operation Step 1. Press (or ) and which you want to set the display range. (or ) to activate the trace for - Press Transform to display the “Transform” menu.

Analysis in Time Domain (Option 010) Deleting Unnecessary Data in Time Domain (gating) range. You can set the center and span by dragging and dropping flags indicating the gate range (Figure 9-10). NOTE Enabling gating function When you enable the gating function, data within the specified range is deleted. When the transformation function is enabled, the flags indicating the gate range is displayed as shown in Figure 9-10. NOTE In Figure 9-10, the gate type is set to band pass.
Analysis in Time Domain (Option 010) Characteristics of Response in Time Domain Characteristics of Response in Time Domain This section describes masking and the identification of the mismatch type, which are important for analyzing the response in the time domain. Masking Masking is a phenomenon in which a mismatch at a location near the calibration surface affects the response at the next mismatch location.
Analysis in Time Domain (Option 010) Characteristics of Response in Time Domain Identifying mismatch type The transformation in the low pass mode simulates the response in the TDR measurement. In addition to mismatch locations, the response includes information on the mismatch type. Figure 9-12 shows each mismatch type and the response waveform corresponding to it. In the low pass mode, you can simulate the response of the step signal and the impulse signal.

12. Optimizing Measurements 12 Optimizing Measurements This chapter describes how to optimize your measurements when using the Agilent E5070B/E5071B.
Optimizing Measurements Expanding the Dynamic Range Expanding the Dynamic Range The dynamic range is the finite difference between the maximum input power level and the minimum measurement power level (noise floor) of the analyzer. In evaluating a characteristic accompanied by a large change in the amplitude (the pass band and stop band of a filter, for example), it is important to increase the dynamic range.
Optimizing Measurements Expanding the Dynamic Range Turning on Sweep Averaging Using sweep averaging also enables you to reduce the effects of random noise on measurements. Sweep averaging averages data from each point (vector quantity) based on the exponential average of a continuous sweep weighted by the averaging factor specified by the user. Sweep averaging is expressed in Equation 12-1.
Optimizing Measurements Reducing Trace Noise Reducing Trace Noise Any of the following methods can be used to lower the trace noise. • Turning on sweep averaging • Turning on smoothing • Narrowing the IF bandwidth For more about sweep averaging and the IF bandwidth, see “Turning on Sweep Averaging” on page 397 and “Narrowing the IF bandwidth” on page 396. Turning on Smoothing Smoothing can be used to reduce noise that has relatively small peaks.
Optimizing Measurements Reducing Trace Noise Figure 12-4 Effects of smoothing (group delay format) 12. Optimizing Measurements Setting up smoothing Set up the smoothing operation by following the steps below. Step 1. Press (or ) and which smoothing will be defined. Step 2. Press (or ) to activate the trace on . Step 3. Press Smo Aperture. Step 4. Change the smoothing aperture (%) in the data entry area. Step 5. Press Smoothing to turn ON smoothing.
Optimizing Measurements Improving Phase Measurement Accuracy Improving Phase Measurement Accuracy This section describes the following functions that can be used to improve phase measurement accuracy. • • • “Electrical Delay” on page 400 “Setting port extensions” on page 403 “Phase offset” on page 402 Electrical Delay Electrical Delay is a function that adds or removes a pseudo-lossless transmission line with a variable length corresponding to the receiver input.
Optimizing Measurements Improving Phase Measurement Accuracy Step 3. Press . Step 4. Press Marker → Delay to set the electrical delay to the group delay value at the position of the active marker (a value smoothed with the aperture of 20% regardless of the smoothing setting). NOTE An absolute value is used regardless of the reference marker mode’s on/off status. 12.
Optimizing Measurements Improving Phase Measurement Accuracy Phase offset Phase offset is a function used to add or subtract a predetermined value relative to the frequency to and from the trace. Using this function enables you to simulate the phase offset occurring as a result of, say, adding a cable. The phase offset can be specified from −360° to +360°. Using the Phase Offset Function Step 1. Press (or ) and which you want to specify the phase offset. Step 2. Press (or ) to activate the trace for .
Optimizing Measurements Setting Port Extensions and Loss Values Setting Port Extensions and Loss Values Setting port extensions Port extension corrects the electrical delay of each test port (phase shift) only. It cannot remove errors caused by the loss in and incorrect matching of cables, adapters, or test fixtures. NOTE You can define port extension channel by channel. Setting port extension for one particular channel does not affect other channels. Operational procedure Step 1. Press extension.
Optimizing Measurements Setting Port Extensions and Loss Values Setting loss values In addition to port extension, you can set loss values for each port. By correcting loss due to port extension, more accurate measurement results are obtained. There are two types of loss value settings: loss values at two frequency points for a specified port, and a DC loss value. You can make these settings at the same time for each port. NOTE You can set loss values channel by channel.
Optimizing Measurements Setting Port Extensions and Loss Values 2. Setting a DC loss value Step 1. Press loss value. Step 2. Press or to activate the channel for which you want to set a DC . Step 3. Press Port Extensions. Step 5. Press Select Port to select the port for which you want to set a DC loss value. Step 6. Press Loss at DC, and enter a DC loss value. Step 7. If you want to set a DC loss value for other ports, repeat Step 5 to Step 6. Enabling port extensions and loss values Step 1.
Optimizing Measurements Setting Port Extensions and Loss Values Using the auto port extension function The auto port extension function measures port extension and loss values for each port using the OPEN/SHORT standard connected to the port, automatically calculates them, and set them. When the auto port extension function is completed, the port extensions and loss values are updated to the calculated values. NOTE You can use both open and short measurement values in the auto port extension function.

Otherwise, the measurement accuracy may be degraded. Procedure Step 1. Press . Step 2. Press Service Menu. Step 3. Press High Temperature to turn ON/OFF the high temperature measurement mode. Chapter 12 411 12.
Optimizing Measurements Improving Measurement Throughput Improving Measurement Throughput This section explains the following three methods to improve the measurement throughput.
Optimizing Measurements Improving Measurement Throughput Swept mode As shown in Figure 12-6, in the stepped mode, the frequency is changed stepwise and sampling is performed at a fixed frequency for each measurement point. On the other hand, in the swept mode, sampling is performed with the frequency always swept for each measurement point.
Optimizing Measurements Improving Measurement Throughput problem before performing the actual measurement. Notes for measuring DUTs with long electrical delay time When sweeping the frequency of a signal applied to the DUT ( F ), there is a frequency difference between the input side and output side of the DUT due to the delay time that occurs in the DUT ( ΔT ).
Optimizing Measurements Improving Measurement Throughput Fast mode The fast mode is a sweep mode in which the sweep time is shortened by decreasing the waiting time before sampling (stepped mode) or speeding up the sweep (swept mode) to the limit of the analog performance.
Optimizing Measurements Improving Measurement Throughput Turning off the updating of information displayed on the LCD screen Turning off the updating of information displayed on the LCD screen eliminates the processing time required to update displays within the analyzer, improving measurement throughput. If it is not necessary to check displayed information during measurements, turning off real-time updating is an effective means of improving throughput.
Optimizing Measurements Performing a Segment-by-Segment Sweep (segment sweep) Performing a Segment-by-Segment Sweep (segment sweep) This section describes the concept of the segment sweep and how to perform it. Concept of Segment Sweep • By skipping the frequency range, which does not need to be measured, you can sweep and measure only the portions you need. • You can define the optimum measurement conditions for each of the segments you designate.
Optimizing Measurements Performing a Segment-by-Segment Sweep (segment sweep) Conditions for setting up a segment sweep The following conditions apply when setting up a segment sweep. • The frequency range of a segment must not overlap with that of another segment. (The start frequency of a segment must be higher than the stop frequency of the immediately preceding segment.

Pushing a front panel key or executing :DISP:CCL command clears the error message. Errors caused by the operation of a front panel key simply appear on the display. They are not stored in the error queue with some exceptions. An error with a positive error number is one uniquely defined for this instrument.
Troubleshooting Error Messages -100 Command error A comprehensive syntax error has occurred showing that this instrument cannot detect a more detailed error. This code simply shows that a command error defined in 11.5.1.1.4, IEEE488.2 has occurred. 60 Continuous switching may damage source attenuator This error occurs when different source attenuator (power range) settings are present during measurement on two or more channels.
Troubleshooting Error Messages -178 Expression data not allowed An expression-data element has been received at a position where this instrument does not accept one. -170 Expression error When the expression data is put to syntactic analysis, an error not corresponding to one of Error Numbers -171 through -179 occurs.
Troubleshooting Error Messages -256 File name not found The file name specified is not found and hence the command is not executed correctly. This error occurs when you try to read a file that does not exist in a disk or a disk is not correctly inserted into the drive to read or write a file, for example. 107 File transfer failed This error occurs when writing data into or reading data from a file (MMEM:TRAN command) fails.
Troubleshooting Error Messages -213 Init ignored Because another measurement is in progress, the request for initiating a measurement (“INIT” command) is ignored. 35 Insufficient ECal module memory This error occurs when the embedded memory is insufficient to save the user property in ECal module during the user definition ECal processing. -161 Invalid block data Block data has been expected, but the block data that appears is invalid for some reason (see 7.7.6.2, IEEE488.2).
Troubleshooting Error Messages The suffix does not comply with the syntax defined in 7.7.3.2, IEEE488.2. Or it does not suit E5070B/E5071B. L 53 Log sweep requires 2 octave minimum span The span of sweep range is not satisfied the requirement for logarithmic sweep. The sweep type is automatically changed to linear sweep when this error occurs. For example, this error occurs when, with the start and stop frequency are set 1 MHz and 2 MHz respectively, the sweep type is changed to logarithmic sweep.
Troubleshooting Error Messages where this instrument does not accept one. O 200 Option not installed The command received has been ignored because of the mismatch between the contents of an option for this instrument and the command. For example, this error occurs when the source attenuator (power range) is set at a value other than zero (SOUR:POW:ATT command) in a model not having the extended power output option.
Troubleshooting Error Messages 222 Port 2 receiver overload The input to Test Port 2 exceeds the maximum input level. The measurement value is not correct. When a DUT is an amplifier or the like, this error may occur, damaging the receiver in the worst case. Should this error occur with a passive part used as the DUT or with nothing connected to the test port, this instrument is faulty. Contact an Agilent Technology sales office or the company from which you bought the instrument.
Troubleshooting Error Messages This error occurs when the previous printing is still in progress or the printer fails (offline, short of paper, etc.) at time of outputting the display image on the LCD screen to the printer (HCOP:IMM command). 121 Print failed This error occurs when printing fails for reasons other than Error 120, Printer error. -284 Program currently running This error occurs when the PROG:SEL:STAT RUN command is executed with the VBA program in the Run state.

The unit is expressed in 12 or more characters (see 7.7.3.4, IEEE488.2). 55 Sweep mode changed to stepped sweep You cannot change the sweep mode to the swept mode.
Troubleshooting Error Messages This instrument receives and detects a trigger command (“TRIG”) or an external trigger signal. But it is ignored due to the timing condition (This instrument is not in the wait-fortrigger state, for example). Change the setup so that a trigger command or an external trigger signal can be sent after the instrument has entered the wait-for- trigger state. U 300 Unable to estimate adapter length Adapter length can not be estimated at zero span.
Troubleshooting Error Messages Ensure the connection of the power sensor. 75 Valid signal generator not found No valid external signal source is connected. This error occurs when the specified type of external signal source is not connected to the specified GPIB address, though the control of the external signal source is enabled (SENS:OFFS:LOC:STAT ON and SENS:OFFS:LOC:CONT ON). It also occurs when USB/GPIB interface is set but not connected.
Troubleshooting Warning Message Warning Message A warning message is displayed in the instrument message/Warning area in the lower left part of the display against a gray background. Pushing a front panel key or executing :DISP:CCL command clears the message. This message simply appears on the display, being not known to a remote environment such as a GPIB.

E. General Principles of Operation E General Principles of Operation This chapter explains the general principles of operation for the Agilent E5070B/E5071B.
General Principles of Operation System Description System Description A network analyzer supplies a sweep signal to a DUT, measures its transmission and reflection, and displays the results as ratios against the input signal from the signal source. The E5070B/E5071B network analyzer consists of the circuit modules shown in Figure E-1. Figure E-1 System Diagram for the E5070B/E5071B Network Analyzer Synthesized Source The synthesized source generates an RF sweep signal in the following frequency range.
General Principles of Operation System Description Source Switcher The source switcher is used to switch test ports to which the RF signal is supplied from the source. Signal Separator The signal separator consists of directivity couplers that detect input and output signals at the test ports. On a test port to which a signal is output, the output signal and the reflection from the DUT are detected as the reference signal (R) and the test signal (T), respectively.
General Principles of Operation Data Processing Data Processing The internal data processing flowchart for the E5070B/E5071B is shown in Figure E-2. Figure E-2 Data Processing Flowchart ADC The ADCs (analog-to-digital converters) convert analog signals fed to the receiver and converted into IF signals (R1, R2, ⋅⋅⋅, Rn and T1, T2, ⋅⋅⋅, Tn) into digital signals. One ADC is available for each signal and the conversion takes place simultaneously.
General Principles of Operation Data Processing IF Range Correction Input signals that went through ranging at the receiver are reverted (corrected) to previous values before the ranging. Ratio Calculation The ratio between two signals is determined by performing divisions on complex numbers. In the case of absolute measurements (Option 008), the ratio of complex number can not be calculated.
General Principles of Operation Data Processing Corrected Data Array Unlike the raw data array, this array stores the results obtained after error corrections, port extensions, or the fixture simulator functions are applied. The user is allowed to read/write data from/to the corrected data array. Corrected Memory Array By pressing - Data → Mem, the contents of the corrected data array will be copied to this array. The user is allowed to read/write data from/to the corrected memory array.
General Principles of Operation Data Processing Display The results obtained after data processing are displayed on the screen as traces. E.
