"Track mode"
If Track is selected in the operator field above, the following field is visible:
The reference channel for the Track function is always the reference channel. The cou-
pling of the inactive channels does not change.
"Split mode: "
If Split is set, coupling can be selected for each channel individually:

Chx Coupling
Used to select the input coupling.
AC or DC coupling can be selected. The selection of the coupling can be performed
with the "AC/DC Coupling" field above it jointly for all channels (Track) or separate of
each other (Split).
DC coupling should be selected if input voltages with very low-frequency signal compo-
nents are to be measured.
"AC" The DC component of the sample signal is removed at the input
using a highpass filter and therefore cannot affect the measurement
result.
"DC" Sample signals up to 0 Hz are recorded and taken into consideration
in the measurement results of RMS, RMS Selective, Peak, DC, FFT
and Waveform.
Note: If the input signal contains a large DC component, this results
in a reduced dynamic range for the AC component, since the mea-
surement range of the input amplifier is based on the overall signal.

Bandwidth
3 different analyzer bandwidths are available; the selected bandwidth determines the
upper frequency limit for the sample signal.
