7.5.4 Interplay of the controlling mechanisms
In the following examples, continuous measurement scenarios are used. But these
scenarios apply also to single measurements. The only difference is that a single mea-
surement is not repeated.
7.5.4.1 Continuous average mode
General settings for these examples:
●
INITiate:CONTinuous ON
●
[SENSe<Sensor>:]AVERage:COUNt 4
●
[SENSe<Sensor>:]AVERage:COUNt:AUTO OFF
Example: Repeating termination control
Further settings for this example:
●
[SENSe<Sensor>:]AVERage:TCONtrol REPeat
The measurement is started by the trigger event. Due to the chopper phases, one
measurement lasts twice the defined aperture time. As defined by the average count,
after 4 measurements, the result is averaged and available. During the whole mea-
surement cycle, the trigger synchronization is high (
TRIGger:SYNC:STATe ON
).
