Used but in excellent condition. these Analog to Digital converters were in service until they were replaced due to an equipment upgrade. Guaranteed working. We have two in identical condition, your price is for one.

The CANBERRA Model 9635 Analog-to-Digital Converter is a single-width NIM family member of the ICB line of programmable front end electronics and has been designed primarily for use in high count rate applications. This highly linear, 8K ADC contributes no system dead time to spectroscopy systems using traditional Gaussian or Triangular Shaping amplifiers.
The Model 9635 boasts differential and integral linearity performance that until now was only possible with Wilkinson ADCs. Its exceptional linearity improves peak shape and resolution, thereby improving the overall performance of the spectroscopy system.
Programmable Gain, Range and Digital Offset allow the user to maximize the use of limited MCA memory by selecting only the specific energy range of interest. This can be particularly useful for multi-input applications such as alpha spectroscopy, thus eliminating the need for older biased amplifiers. These digital controls accomplish the same end more accurately and repeatably.
Conversion for the Pulse Height Analysis (PHA) mode can be programmed for Automatic or Delayed operation. Automatic operation uses an internal constant-fraction peak detector operating on the trailing edge of the input pulse to initiate a conversion. Delayed operation waits up to 100 μs after the leading edge of the input pulse passes the LLD before initiating a conversion. This delay time is ADJustable on the front panel with help from the adjacent Linear Gate signal INSPection test point. Conversions may be enabled/disabled by a Gate input applied at any time during the Linear Gate Interval. Coincidence or Anticoincidence operation is programmable.
