Remote Programming
REAC The REAC command performs the ReAcquire function. The display buf-
fer is restored with original count data from the data acquisition memory.
Reacquire will only function when the SR430 is in the DONE state.
ROFF (?) {i} The ROFF command sets or reads the ReAcquire From Offset value.
The parameter i programs the offset from 0 to the trigger offset in incre-
ments of 16 bins. The value of i is rounded to the nearest multiple of 16.
ROFF may be used when the SR430 is in the DONE state.
DISPLAY CONTROL COMMANDS
AUTS The AUTS command performs the AutoScale function. This function is
exactly the same as pressing the [AUTOSCALE] key. The AUTS com-
mand may affect the BOTM and VSCL parameters below.
CRPK The CRPK command performs the same function as pressing the [PEAK]
key. The cursor region will be centered around the maximum data value
on the screen. The cursor marker position depends upon the cursor
mode.
BUGP? The BUGP? query reads the bin number where the cursor marker is lo-
cated. Using the BUGP? query after the CRPK command reads the posi-
tion of the on screen peak.
CNTR The CNTR command performs the same function as pressing the
[CENTER] key. The graph will be horizontally translated to place the bin
corresponding to the cursor marker at the center of the graph. The LEFT
parameter will be affected.
LEFT (?) {i} The LEFT command sets or reads the number of the bin at the left edge
of the screen. The LEFT i command translates the graph horizontally to
place bin #i at the left edge. The parameter i may range from 0 to the
number of bins per record minus the number of bins per screen, i.e. the
graph may not be translated to display a bin which is beyond the end of
the record.
BOTM (?) {i} {x} The BOTM command sets or reads the minimum displayed Y value. The
BOTM i or BOTM x commands translate the graph vertically to make the
Y value corresponding to the bottom of the graph equal to i or x.
The parameter i is used when the graph displays integer count data. The
value of i may range from -32767 to 32767.
The parameter x is used when the graph displays floating point data. The
value of x is rounded to the nearest 1/10 of a division. Values of x which
translate the data far off screen may be limited to a maximum or mini-
mum value, depending upon the range of the data.
HSCL (?) {i} The HSCL command sets or reads the horizontal screen width. The pa-
rameter i selects a screen width below. The screen width may not be set
such that the screen width plus the left most bin exceeds the number of
bins per record, i.e. the graph may not be scaled to display a bin which is
beyond the end of the record. Unlike horizontal scaling from the front
panel which takes place about the cursor position, the HSCL command
leaves the left most bin fixed while changing the screen width.
