9-27
width. This allows for filtering out of errant or “runt” pulses that may be
caused by noisy environments.
The external trigger input triggers a single pulse for each enabled channel.
External triggering is internally limited to 5 times the maximum set pulse width.
To generate channel pulses in single shot mode with the trigger enabled:
Single Shot Mode (Trigger Enabled)
•
In the system
MODE
menu: Set to ‘Single Shot’ mode.
•
In the system
TRIG
menu:
o
Set trigger mode to ‘Enabled’.
o
Set trigger level.
o
Set trigger edge.
•
In the channel menu: Set desired channels to ‘Enabled’.
•
Verify the rear panel Safety Interlock.
•
Turn Arm Switch to ‘ARM’ Position.
•
Run Pre-Test if enabled and resolve any resulting error conditions.
Pressing the
RUN/STOP
key will now allow a single pulse for each enabled
channel at the next external trigger event.
NOTE: All operation modes require the
Interlock
to be in place and the
Arm
Switch
to be in ARM position.
Special Testing Modes
The 9730 allows the user to setup a pre pulse resistance test that, when enabled,
must run and pass within the user specified range before allowing pulses to be
generated for any enabled channel. To use pre pulse resistance testing:
Pre Pulse Resistance Testing
•
Setup the system mode, period and channel pulse parameters as
described in the
Standard Operation Modes
section.
•
In the Channel Test Menu:
o
Set PreTest to ‘Enabled’
o
Set PreMax to the maximum “Go” resistance
o
Set PreMin to the minimum “Go” resistance
•
Verify the rear panel Safety Interlock.
