Description
The following is the status register structure of the swept signal
generator when the analyzer programming language is selected. This
status structure is the structurally and syntactically the same as on
the HP 8340/41.
OS(2B) Output Status bytes, is used to read the two 8-bit status
bytes from the swept signal generator. The first status byte
concerns the cause of an SRQ (Service Request), while the
second status byte concerns failures and faults, as follows:

Status Byte 1
Bit 0: SRQ caused by a key closure on the front panel of the swept
signal generator (use the OM code to determine the front panel
status).
Bit 1: SRQ caused by the completion of a numeric entry (use the OA
code to determine the value of the numerical entry).
Bit 2: SRQ caused by a change in the extended status byte (status
byte 2) affected by the RE-coded mask (see the RE code for an
explanation of this masking).
