MT = 2 * AC * APER + (2 * AC - 1) * 100
μ
s
with:
MT: overall measurement time
AC: average count
APER: aperture time
100
μ
s 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 disabled.
●
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
The fast measurement setting delivers up to 100 000 measurements per second with-
out any blind time over randomly long time periods. Programming examples are given
in
Chapter 9.2, "Performing the Fastest Measurement in Continuous Average Mode"

<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>
The minimum value is implemented for fast unchopped continu-
ous average measurements. See also
Fast Unchopped Continuous Average Measurement"
on page 122.
