Section 3: Pulse Current Measurements
Model 2308 Portable Device Battery/Charger Simulator User’s Manual
See
To change the trigger level setting for a current range
for information on setting the trigger
level setting for a current range. For the charger channel (#2), the trigger level setting is only
available on the 5 A range.
SCPI programming - pulse current measurements
The commands for pulse current measurements are summarized in
Table 3-3
(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 the PULSE CURR
TRIG NOT DETECTED message to appear.
