Testing Preamp Option (P03, P07); Procedure - Agilent Technologies X Series Manual

Testing Preamp Option (P03, P07)

Instruments containing Options P03, P07 must have the preamp function turned on and tested.

Procedure

1. On the analyzer, press
AMPTD Y Scale
2. Connect the equipment as shown in
and the signal analyzer input.
3. Set the synthesized sweeper amplitude to the value listed in the Nominal Source Amplitude column
in Table 5-2.
4. Set the signal analyzer input attenuation to 0 dB.
5. Set the Span as listed in
6. Record the source amplitude, as measured by the power meter, in the Power Meter Amplitude
column of Table 5-2.
7. On the signal analyzer, press
8. Wait for the analyzer to finish averaging.
9. Press .
Peak Search
10. Record the signal amplitude as measured by the analyzer in the measured amplitude column of
Table 5-2.
11. Calculate the signal amplitude accuracy using the following equation:
Amplitude Accuracy Error = Meas_amp + 30 dB − Power_meter
12. Record the results under the Amplitude Accuracy Error column of
Table 5-2. Amplitude Accuracy Results (Option P03, P07)
