Single-shot is preferable if only a single measurement result is required under fixed
conditions, which is typical for remote-controlled measurements. Continuous mode is
suitable for monitoring the evolution of the measurement results in time and observe
how they depend on the measurement configuration, which is typically done in manual
control. The reset/preset values therefore differ from each other.
Remote command:
CONFigure:AUDio:MEAS<i>:ANALog:REPetition
Stop Condition
Specifies the conditions for an early termination of the measurement:
●
None:
The measurement is performed according to its "Repetition" mode and "Sta-
tistic Count", irrespective of the limit check results.
●
On Limit Failure:
The measurement is stopped as soon as one of the limits is
exceeded, irrespective of the repetition mode set. If no limit failure occurs, it is per-
formed according to its "Repetition" mode and "Statistic Count". Use this setting for
measurements that are essentially intended for checking limits, e.g. production
tests.
Remote command:
CONFigure:AUDio:MEAS<i>:ANALog:SCONdition
Statistic Counter
Defines the number of measurement intervals per measurement cycle (statistics cycle,
single-shot measurement). This value is also relevant for continuous measurements,
because the averaging procedures depend on the statistic count.
For audio measurements a single measurement interval is completed when the
R&S
CMW has acquired a full set of results. The statistic counts for single tone, multi-
tone and FFT noise measurements can be configured individually.
Remote command:
CONFigure:AUDio:MEAS<i>:ANALog:SCOunt
Input Settings
The input settings configure the AF input path.
Path Coupling ← Input Settings
Configures whether the DC component of the AF signal is blocked or measured.
"AC"
The DC component of the measured AF signal (including a possible
DC offset of the input amplifier) is blocked. This ensures accurate
measurements of the AC component. However, the DC component
cannot be measured.
"DC"
Both the DC component and the AC component of the AF input signal
are measured.
Remote command:
CONFigure:AUDio:MEAS<i>:ANALog:PCOupling
Auto Ranging, Maximum Level ← Input Settings
The maximum AF input level expected at the AF connector can be set manually or
automatically. Too high input levels result in the error message "Input Overdriven".
