PSA Functional Tests

Amplitude Accuracy at 50 MHz

Amplitude Accuracy at 50 MHz

Test Limits

Amplitude Accuracy should remain within ±1.0 dB of the measured source value across the
range of source levels and changes in resolution bandwidth. Option 1DS (preamp option)
should remain within ±1.3 dB of measured values.

Test Description

A synthesized sweeper is used as the signal source for the test. The source amplitude is
varied using the signal source amplitude control. The resolution bandwidth is also varied
on the spectrum analyzer. The source amplitude is measured by the power meter and
spectrum analyzer at each setting, and the values compared. The difference between each
pair of measurements indicates the amplitude accuracy.
