Chapter 3 Getting Started Introduction This chapter provides a brief overview of the Anritsu Site Master. The intent of this chapter is to provide the user with a starting point for making basic cable and antenna analyzer measurements. Power On Procedure The Anritsu Site Master is capable of up to 1.5 hours of continuous operation from a fully charged, field-replaceable battery. Built-in energy conservation features allow battery life to be extended.
Chapter 3 Getting Started Cable and Antenna Analyzer Mode Selecting the Frequency For the OSL or FlexCal calibration method the frequency range for the desired measurement must be set. The Site Master will automatically set the frequency when a particular signal standard is selected, or the frequency can be manually set using the F1 and F2 soft keys. To set the frequency to a specific signal standard for an OSL or FlexCal calibration: Step 1. Press the FREQ/DIST key. Step 2.
Chapter 3 Getting Started If a Test Port Extension Cable is to be used, the Site Master must be calibrated with the Test Port Extension Cable in place. The Test Port Extension Cable is a phase stable cable and is used as an extension cable on the test port to ensure accurate and repeatable measurements. This phase stable cable can be moved and bent while making a measurement without causing errors in the measurement.
Chapter 3 Getting Started OSL Calibration Procedures In Cable and Antenna Analyzer Mode, if the Cal Off message is displayed, or the test port cable has been changed, a new calibration is required. The following procedures detail how to perform the OSL calibration. OPEN SHORT CALIBRATION LOAD TEST PORT CABLE (OPTIONAL) RFOUT/REFLECTION TEST PORT S332D 1 2 START CAL AUTO SCALE SAVE SETUP RECALL SETUP 3 5 LIMIT 7 SAVE DISPLAY 9 ON OFF MODE Figure 3-2.

Chapter 4 Cable and Antenna Analyzer Measurements Introduction This chapter provides a description of cable and antenna analyzer measurements, including line sweeping fundamentals and line sweeping measurement procedures, available when the Site Master is in frequency or DTF mode. Line Sweep Fundamentals In wireless communication, the transmit and receive antennas are connected to the radio through a transmission line. This transmission line is usually a coaxial cable or waveguide.
Chapter 4 Cable & Antenna Measurements The performance of a transmission feed line system may be affected by excessive signal reflection and cable loss. Signal reflection occurs when the RF signal reflects back due to an impedance mismatch or change in impedance caused by excessive kinking or bending of the transmission line. Cable loss is caused by attenuation of the signal as it passes through the transmission line and connectors.
Chapter 4 Cable & Antenna Measurements CW Mode/RF Immunity CW mode can be used to maximize sweep speeds of both frequency and DTF measurements. With CW on, sweep times can be twice as fast as with CW off. However, making measurements with CW on will reduce the instrument’s immunity to interfering signals. In a controlled environment, this reduced immunity should not be a problem.
Chapter 4 Cable & Antenna Measurements Procedure Step 1. Press the MODE key. Step 2. Select Freq-Return Loss using the Up/Down arrow key and press ENTER. Step 3. Set the start and stop frequencies, automatically by selecting a signal standard or manually using the F1 and F2 soft keys, as described on page 3-2. Step 4. Calibrate the Site Master as described on page 3-2. Step 5. Connect the Device Under Test to the Site Master. A trace will be displayed on the screen when the Site Master is in the sweep mode.
Chapter 4 Cable & Antenna Measurements Cable Loss Measurement The transmission feed line insertion loss test verifies the signal attenuation level of the cable system in reference to the specification. This test can be conducted with the Site Master in Freq–Cable Loss mode.
Chapter 4 Cable & Antenna Measurements Figure 4-3 is an example of a typical transmission line cable loss measurement trace using a standard calibration. Figure 4-3.
Chapter 4 Cable & Antenna Measurements Distance-To-Fault (DTF) Transmission Line Test The Distance-To-Fault transmission line test verifies the performance of the transmission line assembly and its components and identifies the fault locations in the transmission line system. This test determines the return loss value of each connector pair, cable component and cable to identify the problem location. This test can be performed in the DTF–Return Loss or DTF–SWR mode.
Chapter 4 Cable & Antenna Measurements Figure 4-4 shows an example of a typical DTF return loss measurement trace using a FlexCal calibration. Figure 4-4. Typical DTF Return Loss Trace In the above example: q Marker M1 marks the first connector, the end of the Site Master phase stable Test Port Extension cable. q Marker M2 marks the first jumper cable. q Marker M3 marks the end of the main feeder cable. q Marker M4 is the load at the end of the entire transmission line.
Chapter 4 Cable & Antenna Measurements Increasing the data points increases the sweep time and increases the accuracy of the measurement. CW mode On or Off can also affect sweep speed (see CW Mode, page 4-3 for details). Antenna Subsystem Return Loss Test Antenna Subsystem return loss measurement verifies the performance of the transmit and receive antennas. This measurement can be used to analyze the performance of the antenna before installation.
Chapter 4 Cable & Antenna Measurements The following trace is an example of an antenna return loss measurement trace using a FlexCal calibration.. Figure 4-5. Antenna Return Loss Trace Calculate the threshold value and compare the recorded Lowest Return Loss to the calculated threshold value. Maximum Return Loss = −20 log (VSWR − 1) (VSWR + 1) NOTES: VSWR is the antenna manufacturer’s specified VSWR. Use Handheld Software Tools to convert VSWR to Return Loss, or Return Loss to VSWR.
Chapter 5 Power Monitor Mode Introduction The Site Master with Option 5 installed can be used for making power measurements with broadband RF detectors, such as the 10 MHz to 20 GHz Anritsu 560-7N50B. See the table of available RF detectors on page 1-3. The power monitor displays the measured power results in dBm or Watts.
Chapter 5 Power Monitor Displaying Relative Power Step 9. With the desired base power level input to the Site Master, press the REL soft key. The message area will show REL: ON and the power reading will indicate 100%. Step 10. Press the UNITS soft key to display power in dBm. Since REL is ON, the power reading will be in dBr, relative to the base power level.
Chapter 6 High Accuracy Power Meter Introduction Anritsu's High Accuracy Power Meter (Option 19) enables high accuracy, RMS measurements for both CW and digitally modulated signals such as CDMA/EV-DO, GSM/EDGE, and WCDMA/HSDPA. This option requires either the PSN50 or MA24104A power sensors. The PSN50 power sensor provides high accuracy terminating measurements from 50 MHz to 6 GHz with a dynamic range from –30 dBm to +20 dBm.
Chapter 6 High Accuracy Power Meter Zeroing the Sensor The zero feature improves low-level accuracy by removing measured system noise. Cal Factors correct both efficiency and mismatch loss. The frequency information must be entered to obtain the correct calibration factor. Using Attenuators When necessary, attenuators should be used to ensure that the power does not exceed the specified measurement range. The Offset dB feature can be used to enter the value of any cables and attenuators.
Chapter 6 High Accuracy Power Meter Zero and Cal Step 6. Press the FREQ/DIST key. Step 7. To enter the frequency manually using the number keys, select the Center soft key. To select a known signal standard, press the Signal Standard soft key and use the Up/Down arrow key to select the desired standard. The Cal Factors will be derived for the corresponding center frequency. NOTE: The channel number is not required because the cal factor frequencies are rounded to the nearest 500 MHz. Step 8.
Chapter 6 High Accuracy Power Meter Displaying Relative Power Step 21. Press the AMPLITUDE key. Step 22. With the desired base power level input to the sensor, press the Rel soft key. The message area will show Relative On and the power reading will show 0 dB and 100%. If measuring a 10 dBm signal with the Rel key selected, a drop to 7 dBm will show –3dB and 50%. Saving the Measurement Step 23. Press the SAVE DISPLAY key. Step 24. Use the soft keys to enter a Trace Name.

Chapter 7 Handheld Software Tools Cable List A custom cable list can be created in Software Tools and uploaded to the Site Master. Some standard 1000 MHz, 2000 MHz, and 2500 MHz cables are stored in the Site Master and are listed in Appendix A of this User’s Guide. The cable list contains vital information such as propagation velocity (Vp) and insertion loss (dB/m or dB/ft). These parameters are important when identifying faults and discontinuities of transmission lines.
Chapter 7 Handheld Software Tools To convert from Frequency Domain to Distance to Fault, follow these steps: Step1. Capture a plot or load a previously saved plot. Step2. Click the Distance-to-fault button on the toolbar (or choose Distance-to-Fault from the Tools menu). A dialog will open allowing you to specify the cable parameters, start distance, and stop distance. The cable type may be selected from the pull-down list.

Appendix A Windowing Introduction The FREQ/DIST menu (page 2-11) provides for setting the cable loss and relative propagation velocity of the coaxial cable. The Window key opens a menu of FFT windowing types for the DTF calculation. The theoretical requirement for inverse FFT is for the data to extend from zero frequency to infinity. Side lobes appear around a discontinuity due to the fact that the spectrum is cut off at a finite frequency.
