PROGRAM MESSAGE SYNTAX SUMMARY
•
Common commands begin with an asterisk (*).
•
Queries end with a question mark (?).
•
Program messages consist of a root keyword and, in some cases, one or more message
units separated by a colon (:) followed by a message terminator. Several message units
of a program message may be separated by a semicolon (;) without repeating the root
keyword.
•
If a program message has more than one message unit, then a colon (:) must precede
the next keyword in order to set the parser back to the root (otherwise the next keyword
will be taken as a subunit of the previous message unit).
e.g., the command
meas:volt?;curr?
will read output voltage and output current since
both
volt?
and
curr?
are interpreted as subunits of the
meas
command.
•
Several commands may be sent as one message; a line feed terminates the message.
Commands sent together are separated by a semicolon (;). The first command in a mes-
sage starts at the root, therefor a colon (:) at the beginning is not mandatory. E.g., the
command
meas:volt?;:curr?
will read output voltage and programmed current since the
colon preceding
curr?
indicates that
curr?
is not part of the
meas
command and starts at
the root.
•
UPPER case letters in mnemonics are mandatory (short form). Lower case letters may
either be omitted, or must be specified completely (long form)
e.g.,
INSTrument
(long form) has the same effect as
INST
(short form).
•
Commands/queries may be given in upper/lower case (long form)
e.g.,
SoUrCe
is allowed.
•
Text shown between brackets [ ] is optional.
e.g.,
:[SOUR]VOLT:[LEV] TRIG
has the same effect as
:VOLT TRIG

STATUS REPORTING
The status reporting of the BOP power supply follows the SCPI and IEEE 488.2 requirements.
The serial poll response of the BOP power supply provides summary bits of the status and error
reporting system. The simplest status report is the command valid reporting and data availabil-
ity. The successful decoding of a command string generates no error and is indicated by the bit
3 of the serial poll response being a zero. The setting of bit 4 in the status byte indicates data is
available to the controller in response to a command query message.
