SYSTem:COMMunicate:GPIB:ADDRess
Description:
Set or return the instrument’s primary GPIB address. Use this command with caution, as
GPIB communication could become locked up if proper addressing does not occur.
Syntax:
SYSTem:COMMunicate:GPIB:ADDRess <n>
Argument:
<n> = 0 to 30
Valid Modes:
Any
SYSTem:COMMunicate:GPIB:LISTen
Description:
Set or return the LISTENER line termination (EOS) character. This character is used to
terminate any command the instrument receives over the GPIB. However, since the instru-
ment always responds to an EOI command from the controller, it is not necessary for the
user to transmit the EOS character unless the controller doesn’t set EOI on the last com-
mand byte.
Syntax:
SYSTem:COMMunicate:GPIB:LISTen <asc>
Argument:
<asc> = CR, LF
Valid Modes:
Any
SYSTem:COMMunicate:GPIB:TALK
Description:
Set or return the TALKER line termination (EOS) character(s). This character(s) is sent by
the instrument at the end of any response string it transmits. However, since it always
asserts EOI on the last character of any string, it may not be necessary to use any EOS
character if the controller recognizes the EOI. In this case, set the talk termination to NONE.
Syntax:
SYSTem:COMMunicate:GPIB:TALK <asc>
Argument:
<asc> = NONE, CR, LF, CRLF
Valid Modes:
Any
4.5.19 STATus Commands
The STATus command subsystem enables you to control the SCPI defined status reporting structures. The user may
examine the status of the power meter by monitoring the Operation Status Register
and Questionable Status Register.
Note that IEEE-488.2 commands may be used to monitor device registers (See IEEE-488.2 Commands).
STATus:PRESet
Description:
Sets device dependent SCPI registers to default states. The Operational Enable and Ques-
tionable Enable mask registers are both cleared so an SRQ will not be generated for these
conditions, and the error queue is cleared.
Syntax:
STATus:PRESet
Argument:
None
Valid Modes:
Any
