8. Scale Fidelity
A 50 MHz CW signal is applied to the input of the analyzer through two
calibrated step attenuators. The attenuators are the amplitude
reference standard. The source is adjusted for a response at the
reference level. The attenuators are then set to achieve a nominal
amplitude below the reference level. The analyzer’s amplitude marker
is compared to the actual total attenuation to determine the scale
fidelity error.
The test is performed in both log and linear amplitude scales.
