N5171B/81B Alternative Test Procedure

If a USB power sensor is not available, use a power meter to measure the
output power of the signal generator.
Test Setup 1. Zero and calibrate the power sensor to the power meter:
2. Connect the equipment as shown:
3. Preset the signal generator: Press Preset.
4. Turn RF on: Press RF On/Off so that the RF On/Off LED lights.
5. Turn modulation off: Press Mod On/Off so that the Mod On/Off LED turns
6. Set the frequency: Press Frequency and enter the first frequency value
7. Set the amplitude: Press Amplitude and enter the amplitude value for that
