Display Scale Fidelity Performance Test

This test verifies that the PSA meets its amplitude accuracy specification for amplitude

linearity. The input attenuator is set to 10 dB in zero span mode. The first part of the test

sets the source to 5 dBm and external attenuators are set to 30 dB. The signal is then

measured. The value measured is recorded as the reference level. The RF input is then

varied between the specification intervals of 0 dBm and -17 dBm.

The second part of the test sets the source to -20 dBm and external attenuators are set to 5

dB. The signal is then measured. The value measured is recorded as the reference level.

The RF input is then varied between the specification intervals of -25 dBm and -55 dBm.

Signals below this level are guaranteed by design and are not measured.

NOTE: This test requires step attenuator calibration data to obtain valid results. Make

sure you enter the calibration data for the step attenuators that you're using. Please refer

to the

Enter Equipment Calibration Data section in the TME help for details on how to

enter this data. You must enter the data for the following columns to obtain valid results:

Attn(dB), Uncert(dB) and ReflSize.
