6.2.11 Operation Status Register
The Operation Status Register indicates states which are part of the standard functions of the 2329.
When a bit in the Operation Status Enable Register is enabled, the Operation Status Summary Bit (bit 7) in
the Status Register is set. When bit 7 in the Service Request Enable Register is enabled, a Service Request
is sent to the System Controller if the 2329 is being controlled via the IEC bus. The bits used by the 2329 are:
0 - Calibrating -
The 2329 is performing a calibration.
2 - Ranging
-
The 2329 is changing measurement ranges.
4 - Measuring -
The 2329 is performing a measurement.
8 - EOC
-
End of Conversion: This bit indicates that the 2329 has obtained a valid
measurement
value.
9 - PON
-
The 2329 has been switched on again. This bit will be deleted while reading out
the
register
or
ß
CLS.
The commands for controlling the Operation Status structure are:
STATus:OPERation:EVENt?
STATus:OPERation:ENABle
STATus:OPERation:CONDition?
6.2.12 Questionable Status Register
The Questionable Status Register indicates that the data presently being recorded are invalid for some reason.
When a bit in the Questionable Status Register is set and the corresponding bit in the Questionable Status
Enable Register enabled, the Questionable Status Summary bit (bit 3) in the Status Register is set. When bit
3 in the Service Request Enable Register is enabled, a Service Request is sent to the System Controller if the
2329 is being controlled via the IEEE488.
Bit 14 is the Command Warning bit which indicates that a parameter has been ignored during the processing
of a command.
The commands for controlling the Questionable Status structure are:
STATus:QUEStionable:EVENt?
STATus:QUEStionable:ENABle
STATus:QUEStionable:CONDition?
6.2.13 Standard Event Register
The Standard Event Register indicates various states of the 2329. When a bit in the Standard Event Register
is set and the corresponding bit in the Standard Event Enable Register is enabled, bit 5 in the Status Register
is set. When bit 5 in the Service Request Enable Register is enabled, a Service Request is sent to the System
Controller if the 2329 is being controlled via the IEEE488.
The bits used in the 2329 have the following meanings:
Bit 0 Operation Complete
This bit is set in response to the *OPC command. It indicates that the
device has finished executing the selected operation.
Bit 2 Query Error
A query error was detected. This bit indicates that either:
(1)
data were requested although none are available,
(2)
or data in the output buffer were lost.
