be enabled within the signal path to eliminate noise introduced by higher-fre-
quency components of the input signal.
The bandwidth filter is switched into the signal path using the command:
INPut[{1|2}]:FILTer[:LPASs][:STATe] {OFF|ON}
INPut[{1|2}]:FILTer[:LPASs][:STATe]? (query form)
On - enables the filter. OFF - disables the filter.
Figure 4-3 shows the effects on the instrument’s measurable frequency range
when the filter is enabled.
Figure 4-3. Measureable Frequency Range with Bandwidth Filter Enabled.
From the figure:
DC coupling = 1 mHz - 100 kHz
AC coupling = 10 Hz - 100 kHz
CONFigure and MEASure do not change the filter setting. Following a reset
(*RST) or front panel preset (Preset), the low-pass filter is disabled (off).
