5 - 5 Event-input total count measurement
In the event-input t o t a l count measurement
mode, the t o t a l number of events generated
during a fixed certain period is measured.
T h i s measurement period can be set by using
the f r o n t panel s w i t c h or the rear panel gate
signal input juck.
The signal input c i r c u i t and the counter are
coupled w i t h capacitance ( A C ) , which requires a t
least 5 events per second to be generated.

If the T T L H-level signal is input to t h a t

In this case, the t o t a l numder of events is
