Can I use a 935 controller with any detector and still obtain realtime collection and analysis?
No. The Model 935 is designed for use with a particular type of NaI detector that incorporates a highly efficient, proprietary high voltage bias supply built into the base of the detector. The Model 935 control unit provides 12 V dc power to the detector base along with a 0 – 1 Volt reference that controls the bias voltage for detector operation. The signal does, however, come back from the detector to the controller preamplifier/amplifier much like other systems. This system allows for fully automatic calibration where the Model 935 resets the bias voltage and amplifier gain settings.
