Residual Responses Performance Test

This test applies to the following models:

• All X-Series models

Residual Responses are discrete responses that appear on the analyzer display with no signal applied. They are created within the analyzer by the frequency synthesis and frequency conversion processes. Residuals are the result of imperfect shielding of internal signals, or by other unknown mechanisms.  

In this test, the analyzer’s RF input is terminated with 50 ohms and the attenuator is set to 0 dB. The analyzer is tuned to known residual frequencies.
