Description
f 1 .O dB over 10 to 70 dB range
Input Attenuator Switching Uncertainty Test
A signal source of known amplitude is connected to the spectrum
analyzer and the analyzer is adjusted for a reference. The input
attenuator is stepped down from 10 dB to 70 dB, while the reference
level and the signal source are stepped up. This maintains the signal
peak at the same approximate location on the CRT display. The
amplitude of the signal is measured at each step using the marker
function on the spectrum analyzer.
