Model 2461 Interactive SourceMeter® Instrument Reference Manual Appendix B: Common commands
2461-901-01 A/November 2015 B-3
The instrument returns a decimal value that corresponds to the binary-weighted sum of all bits set in
the register.
Bit Decimal
value Constant When set, indicates the following has occurred:
0 1
status.standard.OPC
All pending selected instrument operations are
complete and the instrument is ready to accept new
commands. The bit is set in response to an *OPC
(on page B-6) command or TSP opc() (on page 8-
92) function.
1 2 Not used Not used.
2 4
status.standard.QYE
Attempt to read data from an empty Output Queue.
3 8 Not used Not used.
4 16 Not used Not used.
5 32 Not used Not used.
6 64 Not used Not used.
7 128
status.standard.PON
The instrument has been turned off and turned back
on since the last time this register was read.
Command errors include:
•
IEEE Std 488.2 syntax error:
The instrument received a message that does not follow the defined
syntax of the IEEE Std 488.2 standard.
•
Semantic error:
The instrument received a command that was misspelled or received an optional IEEE
Std 488.2 command that is not implemented in the instrument.
•
GET error:
The instrument received a Group Execute Trigger (GET) inside a program message.
Constants are only available if you are using the TSP command set. If you are using the SCPI
command set, you must use the decimal values.
Example
*ESE 129
*ESE 129
sets the Status Enable register of the Standard Event
Register to binary
10000001
, which enables the PON and OPC bits.
