Amplitude Accuracy At 50 Mhz - Keysight Technologies N9020A MXA Instruction

Keysight N9020A MXA Signal Analyzer
Functional Tests Guide

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 and external step
attenuator. The resolution bandwidth is also 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.
