Interactive SourceMeter® Instrument Reference Manual Appendix B:
2450-901-01 Rev. B/September 2013 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:
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 8-77) function.
2 4
Attempt to read data from an empty Output Queue.
3 8
An instrument operation did not execute properly due to
an internal condition.
The instrument detected an error while trying to execute
a command.
5 32
A command error has occurred. See information
following this table for descriptions of command errors.
The instrument transitioned from remote control to local
control.
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.
Example
*ESE 145 sets the Status Enable register of the
Standard Event Register to binary 10010001,
which enables the PON, EXE, and OPC bits.
*ESE? might return the string *ESE 186,
showing that the ESER contains the binary value
10111010
