Digitizer Command Reference 95
•
Changing range will keep the level at the same percentage of the new range.
For example, if level is set to 2.0 on the 4V range, the level is set to 8.0 if you
change to the 16V range (50% of full range).
•
Changing range will change an existing level to the same percent of full scale
on the new range (e.g., an 8.0 level on the 16V range and then change range to
4V range changes the level to 2.0V; still 50%) and an error message to be
generated. In this situation, the level is set to the maximum or minimum the
new range will support.
•
The TRIG:SLOPe command specifies which direction of signal movement
through the level will trigger the digitizer.
TRIG:SLOPe is POSitive
causes a
trigger when the signal passes through the level and rises above the specified
level. A trigger occurs when
TRIG:SLOPe is NEGative
and the trigger signal
passes through the level and falls below the specified level.
