The
External stopmode
setting can be used to configure the external stop
input.
A
When selecting
Disabled
, the signal on the input is ignored.
B
When selecting
Rising Edge
, a stop is initiated when a rising edge is
detected.
C
When selecting
Falling Edge
, a stop is initiated when a falling edge is
detected.
The minimum pulse width for both External Start In and External Stop In is
200 ns. Pulses shorter than 200 ns will be ignored.
As the Start/Stop events are software processed events, a one second
response time typically passes before the Start/Stop is executed. After an event
is received, a “disable” time period of 100 ms starts. The same event will not
be detected during the disable time period. For example, if a Start event is
received, a new Start event will not be detected for 100 ms. If, however, a Stop
event occurred immediately after a Start event had been detected, the Stop
event would be detected and processed immediately after the acquisition is
started due to the Start event.
