XTALK (Crosstalk)
The XTALK measurement function is selected by pressing the
FUNCTION XTALK key.
The Crosstalk measurement function measures the amount of signal
that passes from a driven channel (or channels) to a non-driven
channel. On a stereo device, this is also referred to as the ‘stereo
separation’. A bandpass filter is used to tune only the driven
frequency; this rejects the effects of wideband noise on the
measurement.
In Crosstalk measurement function, the selected channel is always the
non-driven channel, and it is from this channel that the main
measurement is taken. The alternate channel is the driven channel,
and its amplitude is measured for comparison to the non-driven
