Frequency Response)
a. Settings are: reference level –20 dBm; input attenuation 10 dB; center frequency 50
MHz; RBW 1 kHz; VBW 1 kHz; amplitude scale linear or log; span 2 kHz; sweep time
coupled, signal at reference level.
b. For reference level 0 to –50 dBm; input attenuation 10 dB; RBW 1 kHz; VBW 1 kHz;
amplitude scale log, log range 0 to –50 dB from reference level; sweep time coupled; sig-
nal input 0 to –50 dBm; span ≤20 kHz.
