SET_OUTPUT_HIGH [output-num]
Sets the Change Sample output to the high level. The DSPEC Pro has only one sample-
changer BNC, therefore, if you include a value for output-num, it must be zero (output-num
is provided for compatibility with other ORTEC instruments). See also STEP_OUTPUT.
SET_OUTPUT_LOW [output-num]
Sets the Change Sample output to the low level. The DSPEC Pro has only one sample-
changer BNC, therefore, if you include a value for output-num, it must be zero (output-num
is provided for compatibility with other ORTEC instruments). See also STEP_OUTPUT.
SET_PEAK_PRESET count
Sets the ROI peak preset to the specified count. During data acquisition when the contents of
any channel of a device that has the ROI flag set reaches the peak preset count, the preset is
complete and the acquisition is stopped. The actual number of counts in the ROI peak may
exceed the preset value by a small number of counts due to the pipelined architecture of the
DSPEC Pro. Setting a peak preset to 0 counts disables the preset. The peak preset may be set
to from 0 (disabled) to 2147483647 counts. See also CLEAR_PRESETS and
SHOW_PEAK_PRESET.
SET_PZ num
This sets the pole zero to num, which must be between 0 and 4095. See also ENABLE_PZ_
AUTO, SHOW_PZ, and DISABLE_PZ_AUTO.
SET_RADIX_BINARY
Not used; included for backward compatibility.
SET_ROI start_chan,number_of_chans
Sets the ROI flags for the specified channels. This command can be used multiple times to
set ROI flags without affecting previously set flags. ROI flags specify channels within a
device that are considered for ROI integral and ROI peak presets.
SET_ROI_MDA start,numchans, [PeakNumber]
Sets the region to use to compute the gross counts in the MDA calculation. PeakNumber is
an optional parameter (assumed 0 if not present) that specifies which of up to 20 (0–19)
MDA Presets to change.
SET_ROI_SAMPLE num
Selects which control signals are displayed as an ROI on the captured waveform. Only a
single bit can be turned on at a time. The following signals can be selected with the
associated bit.
Bit 0:
Pileup reject.
