Bit Description
0 A 1 in this bit position indicates that all pending operations were completed
following execution of the *OPC command.
1 This bit is for GPIB handshaking to request control. Currently it is set to 0
because there are no implementations where the spectrum analyzer
controls another instrument.
2 A 1 in this bit position indicates that a query error has occurred. Query
errors have SCPI error numbers from
−
499 to
−
400.
3 A 1 in this bit position indicates that a device dependent error has occurred.
Device dependent errors have SCPI error numbers from
−
399 to
−
300 and 1
to 32767.
4 A 1 in this bit position indicates that an execution error has occurred.
Execution errors have SCPI error numbers from
−
299 to
−
200.
5 A 1 in this bit position indicates that a command error has occurred.
Command errors have SCPI error numbers from
−
199 to
−
100.
6 A 1 in this bit position indicates that the LOCAL key has been pressed. This
is true even if the instrument is in local lockout mode.
7 A 1 in this bit position indicates that the instrument has been turned off
and then on.
The standard event status register is used to determine the specific event that set bit 5 in the
status byte register. To query the standard event status register, send the command *ESR?. The
response will be the decimal sum of the bits which are enabled (set to 1). For example, if bit
