SET_HV value
This sets the HV bias to value, in volts.
SET_ID “id string”
Sets the sample id string. This string can be up to 16 characters long and can be set to any
arbitrary value. The id string is intended to uniquely identify the sample being analyzed. See
also SHOW_ID.
Examples:
SET_ID “Site 123"
SET_INTEGRAL_PRESET count
Sets the ROI integral preset to the specified count. During data acquisition when the sum of
the counts contained in the channels that have the ROI flag set reaches the integral preset
count, the preset is complete and the acquisition is stopped. The actual number of counts in
the ROI integral may exceed the preset value by up to 512 counts due to the pipelined archi-
tecture of the DSPEC Pro. Setting an integral preset to 0 counts disables the preset. The
integral preset may be set to from 0 (disabled) to 4294967295 counts. See also CLEAR_
PRESETS and SHOW_INTEGRAL_PRESET.
SET_LENGTH_SAMPLE length
Sets the number of points in the Insight mode display to the specified value. Normally this
setting would remain at 1000.
SET_LIVE ticks
Sets the live-time counter to the specified number of ticks. The number represents live time
in units of 20 ms (50 ticks/s). Normally this value is set by the DSPEC Pro during data
acquisition. See also CLEAR_COUNTER and SHOW_LIVE.
SET_LIVE_PRESET ticks
Sets the live-time preset to the specified number of ticks (20 ms/tick). During data acquisi-
tion when the live-time counter reaches the preset number of ticks, the preset is complete and
the acquisition is stopped. Setting a live-time preset to 0 ticks disables the preset. See also
CLEAR_PRESETS and SHOW_LIVE_PRESET.
SET_LLD chan
Sets the lower level discriminator to chan, which must be between 0 and 16383. See also
SHOW_LLD.
SET_MDA_COEF a,b,c
Sets the coefficients in the MDA preset calculation to the specified values. A, b, and c are
floating-point values. The MDA preset checks for the following condition to be met:
