Interpretation of waveform data

As a response to the QW command the oscilloscope sends a set of data describing the waveform. The following example shows the interpretation of that data. The example assumes the Probe Adjust signal to be applied to input channel 1.

For information about MATHPLUS, refer to the supplement for the operation guide.

EXAMPLE:
Settings	Attenuator	200 mV/div
	Coupling	DC
	Offset	-1.5 div = -300 mV offset.
	Time base	200 us/div
	Delay	-2.50 div = 500 us pre-trigger view
