DESCRIPTION
COMMAND SYNTAX
HOR_POSITION, HPOS
Command/Query
The HOR_POSITION command horizontally positions the geo-
metric center of the intensified zone on the source trace. Allowed
positions range from division 0 through 10. If the source trace was
acquired in sequence mode, horizontal shifting will only apply to a
single segment at a time.
If the multiple zoom is enabled, the difference between the speci-
fied and the current horizontal position of the specified trace is
applied to all expanded traces. If this would cause the horizontal
position of any expanded trace to go outside the left or right screen
boundaries, the difference of positions is adapted and then applied
to the traces.
If the sources of expanded traces are sequence waveforms, and
the multiple zoom is enabled, the difference between the specified
and the current segment of the specified trace is applied to all ex-
panded traces. If this would cause the segment of any expanded
trace to go outside of the range of the number of segments of
sources, the difference is adapted and then applied to the traces.
The VAB bit (bit 2) in the STB register (Table 8, page 137 ) is
if a value outside the legal range is specified.
The HOR_POSITION query returns the position of the geometric
center of the intensified zone on the source trace.
<exp_trace>: Hor_POSition <hor_position>,<segment>
<exp_trace> := (EA, EB, MC~:, MD:I:}
<hor..position> := 0 to 10 DIV
<segment> := 1 to 200
Note I: The suffix DIV is optional.
Note 2: The segment number is only relevant for waveforms ac-
quired in sequence mode. The segment number is ignored in single
waveform acquisitions.
