435 Keysight CXG, EXG, and MXG X-Series Signal Generators Service Guide
Functional Tests
Leveled Output Power
N5166B, N5172B, and N5182B Test Procedure
Test Setup 1. Connect the equipment as shown:
2. Zero and calibrate the power sensor.
3. Connect the power sensor to the RF output of the signal generator. Once
the LED on the power sensor turns off, the sensor is ready to measure.
4. Preset the signal generator: Press Preset
5. Turn the internal power meter channel on: Press Aux Fctn > Power Meter
Measurements > Channel A On (or Channel B On).
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
off.
8. Set the frequency: Press Frequency and enter the first frequency value
listed in Table 17-3.
9. Set the amplitude: Press Amplitude and enter the amplitude value for that
frequency.
10.Measure the output power level.
11.Repeat steps 8 through 10 to measure power at each of the frequencies
listed in Table 17-3.
12.Confirm that the measured power levels are within the limits listed in the
table.
Without
Modulation
a. Set the signal generator frequency to the first value listed in
Table 17-3:
Press Frequency > 50 > MHz.
b. Set the amplitude to 7 dBm:
Press Amplitude > 7 > dBm.
USB U2000A Series Power Sensors do not require the sensor to be zeroed
or calibrated.
