a. The effect of scale fidelity on the ratio of two powers is called the relative scale fidelity. The scale fidelity
specified in the Amplitude section is an absolute scale fidelity with 35 dBm at the input mixer as the
reference point. The relative scale fidelity is nominally only 0.01 dB larger than the absolute scale fidelity.
b. See Amplitude Accuracy and Range section.
c. See Frequency and Time section.
d. Expressed in decibels.
