Functional Tests

Amplitude Accuracy at 50 MHz

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.
