The Logger Trigger position appears only
in advanced instrument mode (path:
<Menu>
/ Auxiliary Setup /
Instrument Mode: Advanced Mode).
The Logger Trigger parameters influence
the way the measurement results are saved
in the logger. The Logger Trigger switches
on the result logging.
<ENT>
The logger triggering of the measurements (Enabled) can be switched on
with the <

> push-button.
In this sub-list the triggering of logger can be switched off or on (Enabled),
the parameters of the triggering signal determined (Trigger Parameters),
the number of the results saved in the logger before the fulfilment of the
triggering condition (Pre) and the number of the results saved in the logger
after the fulfilment of the triggering condition (Post) be select. If the
triggering condition is fulfilled, the logger contains:
•
the measurement results registered directly before the fulfilment of the triggering condition; time of the
registration can be calculated by multiplying the value set in the Pre by the time period taken from the
Logger Step (path: Menu / Measurement / Data Logging / Logger Setup);
•
all measurement results up to the moment the triggering condition disappears;
•
the results registered directly after the moment the triggering condition disappears; time of the
registration can be calculated by multiplying the value set in the Post position by the time period taken
from the Logger Step position (path: Menu / Measurement / Data Logging / Logger Setup).
Pre and post trigger registration
In the Pre/Post line the number of the
results registered in the logger’s file
before/after the fulfilment of the triggering
condition can be set. This number is within
the limit 0..20 for Pre trigger and 0..200 for
