Program instruments
Program the Master instrument
1
Program the memory channels as desired.
2
Program scanning rate, recording time and pretriggers as desired.
3
Program the storage start by a trigger (absolutely required, trigger type
can be chosen freely).
4
Program the trigger output
ACTIVE
and set it to
SP_TRIG
(forwarding of
the trigger signal to the Slaves).
Program Slave instruments
1
Program the memory channels as desired.
2
Program scanning rate, storage time and pretrigger in the same way as
the Master instrument.
3
Program the storage start by a trigger. For
Trigger 1
, program the trigger
input
E1
to
ON
.
4
Program the trigger output
AKTIV
and set it to
SP_TRIG
(forwarding of
the trigger signal to the next Slave). This is required for serial coupling,
only.
Start recording
Activate the recording at each instrument normally. Please be aware of:
•
The trigger incident may not happen at the Master instrument, before all
Slave instruments have been activated
•
There must be sufficient time between the activation of the recording and
the occurrence of the trigger incident to allow all instruments to store the
set pretrigger; otherwise the measuring data cannot be synchronized
between instruments.
Example: the pretrigger is 10 sec (20% pretrigger at a recording time of
50 sec) and the trigger incident occurs 5 sec after the recording activation
on the last instrument; this results in a different number of measured val-
ues at the coupled instruments.
•
The storage may not be stopped at any of the coupled instruments, other-
wise a synchronization becomes impossible
•
Avoid cyclic storage due to a possible triggering ahead of the desired time
