Model DMM7510 7½ Digit Graphical Sampling Multimeter Reference Manual Section 8: TSP command reference
DMM7510-901-01 Rev. B / May 2015 8-251
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 6)
command or TSP opc() (on page 8-230) 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.
Example 1
standardRegister = status.standard.OPC + status.standard.QYE
status.standard.enable = standardRegister
Uses constants to set the OPC and QYE bits of the standard event status enable register.
Example 2
-- decimal 5 = binary 0000 0101
standardRegister = 5
status.standard.enable = standardRegister
Uses a decimal value to set the OPC and
QYE bits of the standard event status
enable register.
