Guide to Operation

DISC output should just be terminated at the front

panel.

The GATE outputs are 50 Ω, NIM level, outputs

showing the actual gates to counters A and B. The

GATE outputs are low (-.7 V) during the gate. The

timing accuracy between the GATE outputs and

DISC outputs is 2 ns.

The D/A analog output provides a -10V to +10V

output proportional to the count data with linear or

logarithmic scaling. Output impedance is < 1 Ω

and the maximum current output is 10 mA.

The DWELL output is a TTL level output which is

high whenever the counters are paused. The rising

edge may be used to trigger changes in external

parameters or data acquisition.
