4.7 Status Group Reporting

The state of certain BENCHTOP MICROWAVE SOURCE hardware and operational events and

conditions can be determined by programming the status system. Three lower status groups provide

status information to the Summary Status Byte group. The Summary Status Byte group is used to

determine the general nature of an event or condition and the other status groups are used to

determine the specific nature of the event or condition.

Summary Status Byte Group

The Summary Status Byte group, consisting of the Summary Status Byte Enable register and the

Summary Status Byte, is used to determine the general nature of an BENCHTOP MICROWAVE

SOURCE event or condition. The bits in the Summary Status Byte provide the following:

Operation Status Group

The Operation Status group, consisting of the Operation Condition register, the Operation Positive

Transition register, the Operation Negative Transition register, the Operation Event register and the

Operation Event Enable register.

4.8 Standard Event Status Group

The Standard Event Status group, consisting of the Standard Event Status register (an Event register)

and the Standard Event Status Enable register, is used to determine the specific event that set bit 5 of

the Summary Status Byte.

The bits in the Standard Event Status register provide the following:

Bit Description

0 Set to indicate that all pending BENCHTOP MICROWAVE SOURCE operations were

completed following execution of the “*OPC” command.

1 Request control

2 Set to indicate that a query error has occurred. Query errors have SCPI error codes from –499

to –400.

3 Set to indicate that a device-dependent error has occurred. Device-dependent errors have

SCPI error codes from –399 to –300 and 1 to 32767.

4 Set to indicate that an execution error has occurred. Execution errors have SCPI error codes

from –299 to –200.

5 Set to indicate that a command error has occurred. Command errors have SCPI error codes

from –199 to –100.
