With the level measurements "RMS" and "RMS Selective", the user can decide
whether DC levels are to be taken into consideration or suppressed in the RMS.
This parameter field is not available in the analog analyzer because the suppression
function is already provided by the AC coupling, which can be set up using the hard-
ware.
"deactivated" DC suppression deactivated.
The DC component of the measurement signal is not suppressed
("DC coupling") and is included in the measurement result.
"activated" DC suppression activated.
The DC component of the measurement signal is suppressed ("AC
coupling"); the measurement result includes the AC component only.
For DC suppression in the digital analyzer, the DC level is measured
and subtracted from the total RMS value.
Remote command:
SENSe[1]:FUNCtion:DCSuppression

Filter
Activating a digital filter in the test channel. Depending on the level measurement
method selected, up to 2 user-defined filters or weighting filters can be looped into the
measurement path:
●
RMS, Peak, FFT: max. 2 filters
●
RMS Selective: max. 1 filter in addition to selection filter
●
DC: no filter
The user-definable filters are configured as filters 01 to 09 in the filter panel (see Chap-
ter 5.40, "User-Definable Filters" , on page 469) and can then be used (repeatedly if
necessary) in the analyzer.
For more information on the available weighting filters, see Chapter 5.41, "Weighting
Filters" , on page 478.
Note: Regardless of the digital filters selected here, a further input filter ("prefilter") can
be looped into the test channel. Moreover, the analog bandwidth can be restricted with
the aid of the "Bandwidth" parameter field, which corresponds to an additional lowpass
filter.
Remote command:
SENSe[1]:FILTer<n2>

For a description of the filters and their setting parameters, see Chapter 5.39.4, "Filter
Table" , on page 468.
