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.

Sample Rate Source
Indicates the digital interface used to estimate the sample rate.
"Digital I/Q In"
Estimates the sample rate based on the applied I/Q data clock and
displays the resulting value in the value field. The I/Q data clock sig-
nal is fed via the Dig I/Q input.
Note: Estimation works best if the sample rate is close to the user-
defined value.
