Status Byte 1
Bit 0: SRQ caused by a key closure on the front panel of the
synthesizer (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).
Bit 3: SRQ caused by the completion of phase locking and the
settling of the RF source (use the OK code to determine the last lock
frequency).
Bit 4: SRQ on end-of-sweep or mid-sweep update in NA (network
analyzer code) mode.
Bit 5: SRQ caused by HP-IB syntax error.
Bit 6: SERVICE REQUEST; by IEEE-488 convention, the
instrument needs service from the controller when this bit is set true.
Bit 7: SRQ caused by a change in the coupled parameters (start
frequency, center frequency, and sweep time). Use the OC code to
determine the new values of the coupled parameters.
Status Byte 2 (Extended Status Byte)
Bit 0: Self test failed at power on or at Instrument Preset. This bit
remains latched until this status byte has been read, or until cleared
by the CS or CLEAR 719 commands.
Bit 1: Excessive amplitude modulation input.
