SCPI programming - outputting voltage and current
The commands to output voltage and current are summarized in
Table 2-3
(a listing following the
table contains specific command notes). The programming example (“Outputting and reading back
V and I”) located at the end of this section demonstrates how to use these commands.
NOTE
Setting changes can be canceled by pressing the
MENU
key.
NOTE
Brackets [ ] indicate optional (and default) command parameters
.
