SET_ROI_UNCERTAINTY
start, chans
Sets the region to be used for the uncertainty preset calculation. See also SHOW_ROI_
UNCERTAINTY.
SET_SCA
lllll,uuuuu
Sets the SCA limits with the SCA Output option. lllll is the lower channel and uuuuu is the
upper channel. Use SET_OUTPUT_SEL 2 to route the SCA signal to the Change Sample
Port (or manually set the output option using MCB Properties pages).
SET_SCA_OUTPUT value, active
Sets the SCA output pulse width and whether it is always active. The value is the output
pulse width in microseconds. If active is zero then the SCA pulse is only generated when
acquisition is in progress. If active is one then the SCA pulse is active regardless of
acquisition status. Use SET_OUTPUT_SEL 2 to route the SCA signal to the Change
Sample Port (or manually set the output option using MCB Properties pages).
SET_SEGMENT
No function in the DSPEC 50; included for backward compatibility.
SET_SHAP_FLAT
value
Sets the width of the flattop to value. Value is in microseconds, ranging from 0.3 ìs to 2.4 ìs
in steps of 0.1. See also SHOW_SHAP_FLAT.
SET_SHAP_RISE
value
Sets the rise time to value. Value is in microseconds, ranging from 0.8 ìs to 23 ìs in steps of
0.2. See also SHOW_SHAP_RISE.
SET_SHUTDOWN
index
Used in conjunction with the LIST_SHUTDOWN command to set the high voltage shut-
down setting. Index specifies a position in the list of legal shutdown settings which were
displayed with the LIST_SHUTDOWN command.
