HORizontal:MAIn? Returns the time per division of the
main time base
HORizontal:POSition Sets or returns the waveform’s hori-
zontal position on the display
HORizontal:RECOrdlength Sets the horizontal record length to
the number of data points in each

cord length
HORizontal:RESOlution Sets the horizontal record length to
the number of data points in each
frame and simultaneously adjusts
the sample rate to maintain a
constant time/division
Or returns the current horizontal re-
cord length

Limit Test Command Group
Use the commands in the Limit Test Command Group to perform limit
testing by selecting channel, math, or reference waveforms and compar-
ing them against a template waveform.
Using the limit commands, you can:
H Select a source waveform to compare against the selected template
during a limit test. The source waveform can be a Ch1–Ch4
waveform, a Math1–Math4 waveform, or a Ref1–Ref4 waveform.
(For two--channel instruments, the choices are limited to Ch1–Ch2,
Math1–Math2, or Ref1–Ref2 waveforms.)
H Select a template from the following choices: None and Ref1–Ref4
(only Ref1–Ref2 are available on two--channel instruments).
H Set the limits around a template waveform.
H Reset the instrument to the original limit test default settings. The
default setting for Source is Channel 1 and for Template is None.
