DIG IQ Auto Setting
Activates an automatic adjustment of the baseband input signal.
The R&S SMW receives peak level, level and crest factor values directly from the con-
nected transmitter and recognizes changes automatically.
Remote command:
[:SOURce<hw>]:BBIN:DIGital:ASETting:STATe on page 961
Measurement Period
For CODER connectors:
Sets the recording duration for measuring the baseband input signal by
"Auto Level Set".
Note: For accurate level measurements, set the measurement period to a time value
that is long enough to capture several periods of the input signal.
Remote command:
[:SOURce<hw>]:BBIN:MPERiod on page 962
Auto Level Set
For CODER connectors:
Starts measuring the input signal for estimating the crest factor, the peak level, and the
Revel of the input signal.
See also "Fulfilling the prerequisites for a correct signal processing of the externally
supplied digital baseband signal" on page 121.
Remote command:
[:SOURce<hw>]:BBIN:ALEVel:EXECute on page 962
Crest Factor
Indicates the crest factor of the external baseband signal.
See also Chapter 4.3.5, "Important Signal Parameters and Interface's Characteristics",
on page 119.
Remote command:
[:SOURce<hw>]:BBIN:POWer:CFACtor on page 962
Peak Level
Indicates the peak level of the external baseband signal relative to full scale of 0.5 V (in
terms of dB full scale).
