Audio Precision ATS-1 Access User Manual

Wow and flutter of 3-head tape machines should not be measured
during simultaneous record-reproduce mode, since this will result in
spectral nulls which can give erroneously low readings.
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.
