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:

z General Setting Commands

z Status Commands

z Miscellaneous Commands

The tables also provide a brief explanation of each command.
