Horizontal Command Group
Horizontal commands control the time bases of the instrument. You can set the
time per division (or time per point) of the main time base. You can use the
Horizontal commands to do the following:
Set the scale, horizontal position and reference, and units of the time base
Get the screen resolution, time of first point and time of last point, or get all
the horizontal settings
Enable or disable the display of the time base
You may substitute SECdiv for SCAle in th e horizontal commands. This provides
program compatibility with earlier models of Tektronix instruments.
