Model 2450 Interactive SourceMeter® Instrument Reference Manual
Section 8: TSP command reference
2450-901-01 Rev. B/September 2013
8-163
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
(on page B-6) command
or TSP
(on page 8-77) function.

Not used.
2
4
status.standard.QYE
Attempt to read data from an empty
Output Queue.

status.standard.DDE
An instrument operation did not
execute properly due to an internal
condition.
4
16
status.standard.EXE
The instrument detected an error
while trying to execute a command.
5
32
status.standard.CME
A command error has occurred. See
information following this table for
descriptions of command errors.

64
status.standard.URQ
The instrument transitioned from
remote control to local control.
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.
Example 1
standardRegister = status.standard.OPC + status.standard.EXE
status.standard.enable = standardRegister
Uses constants to set the OPC and EXE bits of the standard event status enable register.
Example 2
-- decimal 17 = binary 0001 0001
standardRegister = 17
status.standard.enable = standardRegister
Uses a decimal value to set the OPC and
EXE bits of the standard event status
enable register.
