Section 4: Long Integration Measurements
SCPI programming
The commands for long integration measurements are summarized in
Table 4-2
(a listing following
the table contains specific command notes).
Programming examples
demonstrate how to use
these commands.
NOTE
Setting the trigger level and/or the current range may cause LONG INT TRIG
NOT DETECTED to appear.
