AMPLITUDE RELATED
Display Modes
10 dB/Div, 2 dB/Div, Linear, and
Delta A.
Display Reference Level
Range
— 123 dBm to +40 dBm (+40 dBm includes
10 dB of IF gain reduction). +30 dBm or 1 W is
the maximum safe input for 10 dB/DIV and
2 dB/DIV log modes. 20 nV/Div to 2 V/Div (1 W
maximum safe input) in linear mode.
Steps
10 dB, 1 dB, and 0.25 dB for relative
(Δ) measurements in log mode. 1 -2-5
sequence and 1 dB equivalent increments
in LIN mode.
Accuracy
Accuracy is a function of the RF attenuation, IF
gain, resolution bandwidth, display mode, refer
ence level, frequency band and response. Refer
to accuracies of these characteristics
The input RF attenuator steps 10 dB for refer
ence level changes above —30 dBm or
—20 dBm when MIN NOISE mode is active un
less the MIN RF ATTEN setting is greater than
normal. The IF gain increases 10 dB for each
10 dB reference level change below —30 dBm
(-2 0 dBm for MIN NOISE mode).
