• Two Identical Triggered Pulse Generators in a single wide NIM module
• Manual or Pulse triggered start
• NIM and ECL output width from 50 ns to 10 s
• End marker output
• Functions as a variable width and rate pulser when both sections are cascaded
The ORTEC 978 Dual Timer is a single width NIM module housing two identical flexible triggered pulse generators. It produces NIM and ECL pulses with width ranges from 50 ns to 10 s when triggered. Output pulses are provided in both normal and complementary formats. A pulse end-marker output signal is provided which can be used to re-trigger the timer for repeat mode. The trigger START can be provided either via an external signal or manually via a front panel switch. The veto input can act as an inhibit gate for the start input signal. The coarse adjustment of the output width is provided via a 10-position rotary switch, while the fine adjustment can be performed via a rotary knob. The two timers may be cascaded to form a pulser with both variable width and rate. Overall accuracy is 10% of full scale plus a temperature coefficient of 0.1% per °C.
