Test Description
The residual response test measures the instrument residual
responses. With the RF 50
Ω
input terminated in a 50
Ω
load, internal
residual responses are measured at various frequencies between
50 MHz and 4 GHz. There are multiple residual responses across the
frequency spectrum of the instrument. The residual responses are
measured at only a few representative frequency points.
