931003E / 0620 4. FIRMWARE COMMANDS AND RESPONSES
SET_GAIN_CHANNEL chan
Sets the center channel for the stabilizer gain peak. If a gain channel is chosen such that the
beginning channel or ending channel would be below channel 0 or above the maximum
channel as determined by the conversion gain, the gain peak width is reduced until the peak
fits the device boundaries.
SET_GAIN_CONV value
Sets the conversion gain to the specified value. Use LIST_GAIN_CONV to determine legal
values.
SET_GAIN_FINE
value
Sets the fine gain to value. Value is a floating point value from 0.4 to 1.2. See also
SHOW_GAIN_FINE.
SET_GAIN_WIDTH chans
Sets the width in channels for the stabilizer gain peak. The gain width must be chosen such
that the beginning channel is no lower than channel 0 and the ending channel is no higher
than the maximum channel as determined by the conversion gain. The gain channel and
width must be set before gain stabilization can be enabled. The absolute minimum width for
the gain peak is 3 channels. See also SHOW_GAIN_WIDTH, SET_GAIN_CHANNEL and
SHOW_GAIN_CHANNEL.
SET_GATE
value
Sets the function of the ENABLE INPUT. Value is used as an index into the list returned by
LIST_GATE. For example SET_GATE 0 turns the ENABLE INPUT off, SET_GATE 1 sets
the ENABLE INPUT to be a coincidence gate, etc.
SET_HV
value
This sets the HV bias to value, in volts, and stores value as the target HV.
SET_LIVE_PRESET ticks
Sets the live-time preset to the specified number of ticks (20 ms/tick). During data
acquisition 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
chans
Sets the lower level discriminator to chan, which must be between 0 and [conversion
gain
!
1]. See also SHOW_LLD.
