N5172B/82B Test Procedure

Test Setup 1. Connect the equipment as shown:
2. Zero and calibrate the power sensor.
USB U2000A Series Power Sensors do not require the sensor to be zeroed or calibrated.
3. Connect the power sensor to the RF output of the signal generator. Once
4. Preset the signal generator: Press Preset
5. Turn the internal power meter channel on: Press Aux Fctn > Power Meter
6. Turn RF on: Press RF On/Off so that the RF On/Off LED lights.
7. Turn modulation off: Press Mod On/Off so that the Mod On/Off LED turns
8. Set the frequency: Press Frequency and enter the first frequency value
9. Set the amplitude: Press Amplitude and enter the amplitude value for that
10.Measure the output power level.
11.Repeat steps 8 through 10 to measure power at each of the frequencies
12.Confirm that the measured power levels are within the limits listed in the
