Description

Lecroy 2323 Prog Dual Gate and Delay Generator - CAMAC data acquisition module/bin.
Was working when last used. Not recently tested and is being sold "AS IS".
Details:-
LeCroy's CAMAC Model 2323 is a fully programmable gate and delay generator packaged with two channels in a double width CAMAC module. Its gate duration is programmable over the range 100 nsec to 10 seconds, covering a dynamic range of eight orders of magnitude. Outputs as short as 50 nsec can be selected at the expense of accuracy and stability. All settings may be programmed under CAMAC control or via front panel switches. Under CAMAC control, settings are overwritten whereas they are incremented under manual control. The Model 2323 offers excellent stability and jitter properties with 0.2% of Full Scale accuracy in the gate setting.
The Model 2323 offers both Start and Stop inputs. This allows the output pulse width to be determined by the Start - Stop time difference in the latched mode or by the internal timer in the preset mode. A Blanking NIM input causes a notch to be taken out of the gate, equal in duration to the blanking input. This is especially useful to gate off data acquisition during spurious periods. Conversely, a NIM OR input causes all outputs to be set to true for the duration of the OR inputs.
The unit offers NIM and NIM outputs equal in duration to the gate width selected. In addition, a DELAY output is produced at the trailing edge of the Gate pulse. The Model 2323 also provides a differential ECL output and a TTL output capable of driving a NIM Bin Gate. Both the ECL and TTL outputs may be driven from either the Gate or Delay circuit. These options are selected by board mounted shorting plugs.
The gate duration and width of the Delayed output are programmable under CAMAC control. Each of the two channels may be set independently. All values which are loaded into the Model 2323 may also be read back via CAMAC. Programming of the delay involves a ten bit "mantissa" and a three bit "characteristic".
The Start input is normally configured to accept NIM signals. A bridged high impedance input is employed t o allow the trigger of more than one channel of 2323. The front end of the Start input consists of a comparator circuit, factory adjusted to trigger at - 400 +/- 50 mV. A front panel accessed multiple turn potentiometer allows the user to adjust the threshold over the range - 3 V to + 3 V. This allows the unit to be triggered by NIM, ECL, TTL or other standard logic signals. A front panel accessed switch selects either the positive-going or negative-going edge as the trigger. The stop input accepts NIM standard pulses.
