Performance Tests
16. Harmonic Measurement Accuracy (Option 002 Only)
10.On the network analyzer, press . Write the
marker 1 reading in the “Input A Value” column on the performance test record.
11.On the network analyzer, press
to set the analyzer to the next fundamental frequency.
12.On the external source, set the CW frequency to 62 MHz. Reset the power meter for the
appropriate calibration factor.
13.Record the power meter reading on the performance test record.
14.On the network analyzer, press . Write the
marker 1 reading in the “Input A Value” column on the performance test record.
15.On the external source, set the CW frequency to 93 MHz. Reset the power meter for the
appropriate calibration factor.
16.Record the power meter reading on the performance test record.
17.On the network analyzer, press . Write the
marker 1 reading in the “Input A Value” column on the performance test record.
18.Repeat steps 11 through 17 for the CW frequencies listed on the performance test
record.
NOTE For Option 006 analyzers, use the 8481A sensor when the external source is
set to 6 GHz. Zero and calibrate the power meter for this sensor.
19.For each measurement, calculate the difference between the measurement and the
power meter level.
20.Write the calculation results in the performance test record.
21.Compare the results with the specification.
B Channel Harmonic Measurement Accuracy
1. Move the RF cable from port A to port B on the analyzer.
2. Repeat steps 2 through 21 of the previous procedure with the following modifications:
• Do not rewrite the power meter readings on the performance test record.
• Write the marker 1 values in the “Input B Value” column of the performance test
record.
