Calculating the measurement time
Normally, the measurement time is calculated as follows:
MT = 2 * AC * APER + (2 * AC - 1) * 100
μ
s
with:
MT: overall measurement time
AC: average count
APER: aperture time
100 μs is the time for switching the chopper phase.
Using [SENSe<Sensor>:][POWer:][AVG:]FAST ON, you can accelerate the mea-
surement as follows:
●
Chopper is deactivated.
●
Average count is set to 1, no matter which average count you have set.
Thus, the overall measurement time is only defined by the aperture time, and the mea-
surement time for a fast measurement is calculated as follows:
MT = APER
A programming example is given in Chapter 10.2, "Performing the Fastest Measure-
ment in Continuous Average Mode", on page 128.

[SENSe<Sensor>:][POWer:][AVG:]APERture <integration_time>
Sets the duration of the sampling window in the continuous average mode. During this
time interval, the average signal power is measured.
Parameters:
<integration_time> Range: 10.0e-6 to 2.00
*RST: 0.02
Default unit: Seconds
Example:
APER 0.02
Manual operation: See "Aperture Time" on page 46
[SENSe<Sensor>:][POWer:][AVG:]BUFFer:CLEar
Clears the contents of the result buffer in continuous average mode.
