Measurement Period
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 687
Auto Level Set
Starts measuring the input signal for estimating the crest factor, the peak power, and
the RMS power of the input signal.
See also "Fulfilling the prerequisites for a correct signal processing of the externally
supplied digital baseband signal" on page 439.
Remote command:
[:SOURce<hw>]:BBIN:ALEVel:EXECute
on page 687
Crest Factor
Indicates the crest factor of the external baseband signal.
See also "Important Signal Parameters and Interface's Characteristics" on page 438.
Remote command:
[:SOURce<hw>]:BBIN:POWer:CFACtor
on page 687
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).
See also "Important Signal Parameters and Interface's Characteristics" on page 438.
Remote command:
[:SOURce<hw>]:BBIN:POWer:PEAK
on page 688
Level
Indicates the estimated RMS level acquired with "Auto Level Set".
