Conversion Gain
Sets the devices’ conversion gain. It can be set from 256 to the maximum number of
channels supported by the device. The gain will change by a factor of two.
ADC Range
Sets the devices’ ADC conversion range. It can be set from 256 to the maximum num-
ber of channels supported by the device. Typically the ADC range and the conversion
gain will be set to the same value.
Fast Discriminator Mode
Sets the devices’ Fast Discriminator threshold mode. AUTO allows the threshold to
be optimized automatically above the system noise level; MANUAL allows the thresh-
old to be manually adjusted.
Fast Discriminator Setting
Sets the devices’ Fast Discriminator threshold level (when MANUAL Fast
Discriminator Mode is selected). The range is 0 to 100%.
Input Polarity
Sets the device’s Input signal polarity to either positive or negative. If you are using a
TRP preamplifer, the Inhibit Polarity control matches the polarity of the device’s In-
hibit (reset) input to the polarity of the preamplifier’s Inhibit output.
Inhibit Polarity
Sets the device’s Inhibit signal polarity to either positive or negative. If you are using
a TRP preamplifer, the Inhibit Polarity control matches the polarity of the device’s In-
hibit (reset) input to the polarity of the preamplifier’s Inhibit output.
Rise Time
Symmetrically sets the rise time and fall time of the digital filter time response. As
with conventional Gaussian shaping, the degree of noise filtering is proportional to the
rise time selection. The rise time can be selected from 35 rise/fall times ranging from
0.4 to 28
µ
s. The software will choose the closest allowable number based on the num-
ber you enter.
Flat Top
Sets the flat top portion of the digital filter time response. The flat top matches the fil-
ter to the detector charge collection characteristics to minimize the effects of ballistic
deficit. The flat top time can be selected from 21 flat top selections ranging from 0 to 3
µ
s. The software will choose the closest allowable number based on the number you
enter.
