XYZ format compares the voltage levels of the CH 1 (X) and CH 2 (Y) waveform
records point by point as in XY format. The displayed waveform intensity is
modulated by the CH 3 (Z) waveform record. XYZ format is not triggered. XYZ
format is not available on 2+2 channel oscilloscopes. A –5 division signal
(including position and offset) on CH 3 produces a blank screen; a +5 division
signal produces full intensity.
