Amplitude Accuracy at 50 MHz

Testing Preamp Option (P03, P08, P13, P26)

Testing Preamp Option (P03, P08, P13, P26)
Instruments containing Options P03, P08, P13, P26 must have the preamp
function turned on and tested.

Procedure

1. On the analyzer, press AMPLTD Y Scale, More, Internal Preamp, Low Band.
2. Connect the Low Power Sensor to the Power Meter, then zero and
3. Connect the equipment as shown in
4. Set the synthesized sweeper amplitude to the value listed in the Nominal
5. Set the signal analyzer input attenuation to 0 dB.
6. Set the Span as listed in
7. Record the source amplitude, as measured by the power meter, in the
8. On the signal analyzer, press Restart.
9. Wait for the analyzer to finish averaging.
10.Press Peak Search.
11.Record the signal amplitude as measured by the analyzer in the measured
12.Calculate the signal amplitude accuracy using the following equation:
13.Record the results under the Amplitude Accuracy Error column of
