Table 3-7 GP-IB Commands (continued)
Command
*Range or **Response
To Query Description
Page
TEST? **TEST xx Causes power supply to run selftests and report
any failures. Type of tests run depends on whether
power supply output is on or off.
63
ID? **Agilent 603xA or
**Agilent 603xA, OPT 100
Causes power supply to report its model number
and any options that affect the unit’s output
capability.
65
[Bracketed commands are equivalent.
x = any digit (within range)
MV = millivolt
MA = milliamp
MS = millisecond
** Query causes power supply to clear output buffer, gather requested data, and store it in output buffer. Data will be put
on GP-IB when power supply is addressed to talk and ATN goes false. Only most recently requested data is stored, and it
is not saved after being put on GP-IB.
Terminators For Data Sent To Power Supply. Terminators mark the end of a command string, and they instruct the power
supply that the command it has just received should be executed. The terminator characters are the line feed and semicolon.
Line feed is sent by all Agilent controllers automatically after OUTPUT statements unless deliberately suppressed, so the
user need not include a terminator when only one command is sent per line. If the user wishes to send more than one
command per line the commands must be separated by semicolon.
Any number of consecutive terminators is treated as one. A terminator may be preceded or followed by any number of
spaces, for example:
VOUT 15V;IOUT 5A
VOUT 15V ; IOUT 5A
are both correct
The carriage return character by itself is not sufficient to terminate a command, but it will be accepted without error in all
cases where a terminator is expected.
Commands may also be terminated by asserting EOI on the GP-IB concurrently with the last character of the command. For
example:
VSET 1.23
E
O
I
requires no semicolon or linefeed. Asserting EOI in conjunction with a terminator will have no adverse effect.
