PST & PSS & PSH SERIES PROGRAMMABLE POWER SUPPLY
PROGRAMMER MANUAL
13
Because the programmable power supply hypothesis that a command
starts from the root, you have the option of beginning the initial
command header with a colon (
:
).
Combining Commands
You can use a semicolon (;) to combine commands. But continuously
query command will cause
message
missing. For example:
CHAN1:VOLT ?;CURR ?
If the command that follows the semicolon has a different header path
from the root level, you must use a colon to force a return to the root
level:
:CHAN1:VOLT 1.23 ;:OUTP:COUP:TRAC 1
If the command that follows the semicolon has the same header path, you
may omit the colon and the path and state only the new leaf node. For
example:
:CHAN1:VOLT 12.34;CHAN1:CURR 1.55
is equal to
:CHAN1:VOLT 12.34;CURR 1.55
You can combine commands and queries into the same message. Note,
for example, the following combination:
:CHAN1:VOLT 12.34;VOLT ?
Synopsis of Commands
The tables in this section summarize the command of the programmable
power supply. These tables divide the commands into three functional
classifications:
l
General Setting Commands
l
Status Commands
l
Miscellaneous Commands
The tables also provide a brief explanation of each command.
