Arguments
NR2 is the fraction of the record at which the horizontal reference point is set. The
range is 0 through 1 (corresponding to 0% through 100% of record); the default
is 0.5. The resolution is 0.01.
Examples
HORIZONTAL:MAIN:REFPOINT 2.5E-1 sets the horizontal reference point
for the Main timebase to 0.25 (25%). This is the point around which the
HORizontal:MAIn:SCAle command contracts or expands the waveform.
HORIZONTAL:MAIN:REFPOINT? might return HORI ZONTAL:MAIN:REFP OINT
.50000000000
, indicating that the horizontal reference p oint for the Main
timebase is set to 0.5 (50%), which is the default.
HORizontal:MAIn:RESolution? (Query Only)
This query only command re turns the current resolution per sample of the Main
timebase. This value is the same as the value displayed in the Resolution field in
the Timebase section of the Horizontal Setup dialog box. You cannot directly set
the resolution. Instead, the use the HORizontal:MAIn:SCAle command to set the
horizontal scale and the HORizontal:MAIn:RECORDLength command to set the
record length. Reso
lution is displayed in horizontal units, typically time.
