Bit Name Usage
0 OPC Set by *OPC
1 unused
2
Query Error Set by an output queue over fl ow
3 Recall Err Set if a stored se ing is corrupt
4 Execution Err Set by an out-of-range parameter or
incomplete command.
5 Command Err Set by a command syntax error or an

6 URQ Set by any key press
7 PON Set by a power-on condition
This status byte is de fi ned by IEEE488.2 (1987) and is used primar-
ily to report errors in commands received over the communication
interface. Once set, the bits in this register stay set, and are cleared
when read or when a
*CLS command is received.
If a bit in the standard status register is set, and the corresponding
bit in the standard status enable register is set, then the ESB bit in
the serial poll register is set.
If an error occurs due to an incomplete command, the following er-
ror messages will appear on the middle display:
Err6 Syntax Error Over GPIB
The command has an error in syntax or was unrecognizable.
This is the same error as seen in the Command Error (bit 5)
of the Standard Event Status Byte.
Err7 Illegal Parameter Entered Over GPIB
A parameter was set out-of-range, or a command could not
be completed because of an overload condition. This is the
same error seen in the Execution Err (bit 4) of the Standard
Event Status Byte.
Err8 GPIB Output Queue Full
The output queue over fl owed and was cleared. This could
be due to querying the instrument repeatedly and not
