Test Description
A 50 MHz CW signal is applied from a synthesized sweeper to the input of the analyzer.
The source is adjusted for a response at the reference level. The synthesized sweeper
amplitude is adjusted to achieve a nominal amplitude below the reference level. The
analyzer’s amplitude marker is compared to the actual source change to determine the
scale fidelity error. Most of the error is the source’s output attenuator inaccuracy from the
synthesized sweeper.
