Storing Waveforms - Extech Instruments MS420 User Manual

This mode is only applicable to simultaneous CH1 and CH2 measurements. The X-Y
format plots the CH1 input as X-axis and CH2 input as Y-axis. This display mode is
convenient for viewing the phase relationship between CH1 and CH2; if the
oscilloscope does not detect triggering the data appear in light spots.
Description of Control Keys:
■ The CH1 VOL and CH1 ZERO keys for CH1 are used to set the horizontal
scale and position.
■ The CH2 VOL and CH2 ZERO keys for CH2 are used to set the vertical
scale and position continuously.
The following functions are not available in the XY display mode:
■ Reference or digital value waveform
■ Cursor
■ Time base control
■ Trigger control
