Input Filter Commands
See also page 55 in Chapter 3.
Using the input filters from the remote interface is not recommended. To
use the filters with the remote interface be aware of the following:
• The digital filter is a moving average (boxcar) filter. The filter rate sets
the number of readings that will be averaged. A reading is taken and
included in the average with each trigger. You must, therefore, supply
enough triggers to fill up the average before the filter will settle. If
your measurement requires averaging readings, use the math
operations (Stats) instead of the digital filter (see page 148).
• The digital filter average may reset, based upon the measurement
value (see page 57). You must use the STATus:OPERation:CONDition
register to determine if the filter is settled with each reading taken.
• The analog filter significantly slows the reading rate.
The input filters are disabled following a remote interface reset (*RST) or
preset (SYStem:PREset).
