Vertical Commands
Vertical commands control the display of channels and of main and reference
waveforms. Table 2–20 lists these commands.
The SELect:<wfm> command also selects the waveform many commands in
other command groups use.
You may replace VOLts for SCAle in the vertical commands. This provides
program compatibility with earlier models of Tektronix digitizing oscilloscopes.
