N9030B PXA Signal Analyzer Service Guide 585
Functional Tests
Amplitude Accuracy at 50 MHz
Amplitude Accuracy at 50 MHz
Test Limits
Amplitude Accuracy should remain within 1.13 dB of the measured source
value across the range of source levels and changes in resolution bandwidth.
The preamp (Option P03, P08, P13, P26) should remain within ±1.3 dB of
measured values.
A synthesized sweeper is used as the signal source for the test. The source
amplitude is varied using the signal source amplitude control. The attenuation
and resolution bandwidth are varied on the signal analyzer. The source
amplitude is measured by the power meter and signal analyzer at each setting,
and the values compared. The difference between each pair of measurements
indicates the amplitude accuracy.
