564 Operating Manual 1403.7458.32 ─ 14
Parameters:
<Type> AUTO | USER | NSRatio
AUTO
The filter length is automatically selected depending on the mea-
sured value. For high values, a short filter length is selected and
for low values a long filter length is selected.
USER
The filter length is set manually. As the filter length works as a
multiplier for the measurement time, this results in a constant
measurement time.
NSRatio
The filter lenghth (averaging factor) is selected so that the sen-
sor's intrinsic noise (2 standard deviations) does not exceed the
specified noise content. The desired noise content is entered
with command
SENSe:FILTer:NSRatio
.
To avoid very long settling times when the power is low, the
averaging factor can be limited with the Timeout parameter
(command
SENSe:FILTer:NSRatio:MTIMe
).
*RST: AUTO
