Rubidium™ MG362x1A SeriesLow-Noise RF/Microwave SignalGenerators : Operation Verification : Power Level Accuracy Test Procedure
 
Power Level Accuracy Test Procedure
Power level accuracy is checked by stepping the power down in one dB increments from the maximum rated power level.
1. Set up the MG362x1A as follows:
a. Reset the instrument by pressing 3-Line Icon | SETTINGS | RESET | FACTORT RESET. Upon preset, the FREQUENCY menu is displayed with frequency and power level set to default values.
Note 
The power level accuracy test records are generic to all models and option configurations. Not all of the power level settings may apply to your specific model configuration. Start with the highest specified power level as indicated in the technical data sheet that was shipped with your instrument.
b. Press FREQUENCY button to open the current frequency parameter for editing.
c. Set the frequency to the CW frequency listed in Table: Power Level Accuracy Test Record.
d. In the same menu screen, press the LEVEL button to open the current power level parameter for editing and set LEVEL to the maximum specified power level noted in the data sheet (use a fixed attenuator when measuring power levels above +19 dBm).
2. Measure the output power level with the power meter and record the power meter reading on the test record (ensure that any fixed attenuation value is added to the reading).
3. Verify that the measurement meets the specifications listed on the test record.
4. Set LEVEL to the next test power level on the test record. Record the power meter reading on the test record and verify that it meets specification (ensure that any fixed attenuation value is added to the reading).
5. Repeat step 4 for the remaining power levels in Table: Power Level Accuracy Test Record for the current CW frequency.
6. Repeat steps 1 through 5 for all CW frequencies Table: Power Level Accuracy Test Record.

1 Specification is ± 1.0 dB for standard power instruments and 1.5 dB for high power (Option 15) instruments.

2 Ensure that a fixed attenuator is used to protect the power sensor from input overload.
