Miscellaneous
The Miscellaneous tab displays settings to select the preamplifier type, TRP
characteristics, and input attenuation.
Figure 53: Miscellaneous Gain Hardware Settings
Attenuate
When set to ON, enables a divide by four input/gain attenuator to minimize overload due
to preamp signals with large DC offsets and Reset Preamps with large output ramp
dynamic range.
When set to OFF, the signal attenuation is removed. Default is Off. For better signal-to-
noise characteristics the Attenuator should be Off.
Refer to the Coarse Gain setting in the General tab on page 104 for additional
information on making gain selections.
TRP Inhibit Mode
Selects the TRP Inhibit Mode to Auto or Manual. In Auto, the signal processing is gated
off for the greater of the external RESET signal OR the Internal Inhibit Time which is
shaping-dependent. This is calculated as 2.5 * (2 * Rise Time + Flat Top).
In Manual mode, the signal processing is inhibited for the greater of the user-selected TRP
Inhibit Time OR the external RESET signal OR the Internal Inhibit Time.
TRP Inhibit
This setting is in effect when the TRP Inhibit Mode is set to Manual. Sets the TRP Inhibit
Time to a value from 0 to 160 μs in steps of 10 μs.
TRP Gate Polarity
Selects either Positive or Negative input polarity for the TRP Gate input signal.
