Model 9650A
Four-Channel Digital Delay Generator
The model 9650A is a four channel digital delay/pulse generator. It produces four adjustable-width output pulses, A, B, C and D, each of which can be delayed from a reference time pulse output T0 by a predetermined amount. It also has two additional difference outputs, A.B and C.D, representing pulses which start on the rising edge of one output and finish on the rising edge of a second.

The instrument is triggered either by its own internal clock or by an external trigger and generates a timing pulse, T0, approximately 35 ns later. This is the time datum to which all other outputs of the unit are referenced. The four delays are adjustable over the range 0 to 100 ms with a 10 ps resolution with the output pulse widths (A, B, C and D) being variable from 30 ns to 1 ms.

The model 9650A is the ideal instrument for delaying trigger signals in signal recovery applications or for synchronizing multiple laser experiments where accurate time relationships are essential.
