a. Absolute amplitude accuracy is the total of all amplitude measurement errors, and applies over the fol-
lowing subset of settings and conditions: 1 Hz
≤ RBW ≤ 1 MHz; Input signal −10 to −50 dBm; Input
attenuation 10 dB; all settings auto-coupled except Swp Time Rules = Accuracy; combinations of low
signal level and wide RBW use VBW
≤ 30 kHz to reduce noise. When using FFT sweeps, the signal
must be at the center frequency.
This absolute amplitude accuracy specification includes the sum of the following individual specifica-
tions under the conditions listed above: Scale Fidelity, Reference Level Accuracy, Display Scale
Switching Uncertainty, Resolution Bandwidth Switching Uncertainty, 50 MHz Amplitude Reference
Accuracy, and the accuracy with which the instrument aligns its internal gains to the 50 MHz Ampli-
tude Reference.
