a. Channel BW is set to 15 times of Rate (Rate 50 kHz) or 10 times the Rate (50 kHz < Rate 100 kHz).
b. SINAD [dB] can be derived by 20  log10(1/Distortion).
c.
FM rejection describes the instrument's AM reading for an input that is strongly FMed (and no AM); this specifi-
cation includes contributions from residual AM
d.
Residual AM describes the instrument's AM reading for an input that has no AM and no FM; this specification
includes contributions from AM depth accuracy.
