Verification
4-1 Introduction
This chapter provides the procedures for verifying the performance or the functionality of various options in
the MS2026C, MS2027C, MS2028C, MS2036C, MS2037C, and MS2038C VNA Master. The test procedures
consist of the following:
• “Power Monitor (Option 5) Verification” on page 4-1
• “Bias Tee (Option 10) Operational Check” on page 4-4
• “GPS (Option 31) Operational Check” on page 4-6
• “Spectrum Analyzer Frequency Accuracy with GPS On” on page 4-8
4-2 Power Monitor (Option 5) Verification
If the Power Monitor (Option 5) is installed in the MS2026C, MS2027C, or MS2028C VNA Master, then the
following test can be used to verify the accuracy of the power measurements.
Equipment Required
• Synthesized Signal Generator, Anritsu Model MG3692X with Option 2A and Option 4 (or Option 5)
• Power Meter, Anritsu Model ML2438A
• Power Sensor, Anritsu Model MA2442D
• RF Detector, Anritsu 560-7N50B
• Power Splitter, Aeroflex/Weinschel Model 1870A
• RF Coaxial Cable, Anritsu Model 15NN50-1.0B
• Adapter, Anritsu Model 34RKNF50
Procedure
1. Press the On/Off key to turn on the VNA Master.
2. Press the Shift key and the Preset (1) key, and then the Preset soft key to reset the instrument to the
default starting conditions.
3. Press the Shift key and then the Mode (9) key. Select Power Monitor and press the Enter key.
4. Set the MG3692X output to 1.0 GHz CW.
5. Connect the Power Sensor to the Power Meter.
6. Zero and calibrate the Power Sensor.
7. Set the Power Sensor Cal Factor to 1 GHz.
8. Connect the MG3692X, Power Meter, Power Sensor, and RF Detector as shown in Figure 4-1.
Note Before continuing, allow a 30-minute warm up for the internal circuitry to stabilize.
