event status register to be set.
Error Code
Error Message Description
-400
Query error (generic)
This is the generic query error for devices that cannot detect
more specific errors.
-410
Query INTERRUPTED
Received a new command before the response was read.
-420
Query
UNTERMINATED
The controller attempted to read the response after the device
received an unsupported query or has not received a query.
The -100 "COMMAND ERROR" and this error is stored in the error
queue. The controller will time out.
-430
Query DEADLOCKED
The error queue, input buffer, and output buffer are full when
sending large binary data as a response, and the transmission
timing is off.
-440
Query
UNTERMINATED after
indefinite response
Received a separate query in semicolon-delimited format after a
query that returns a response in an indefinite form.
(Example: A command such as the following. *IDN?;SYST:ERR?)
Operation complete event errors
An error in the range [-899, -800] is used when the PAT-T wishes to report an IEEE488.2
operation complete event. This event occurs when the instrument?s synchronization
protocol, having been enabled by an *OPC command, completes all selected pending
operations.
The occurrence of any event error in this class shall cause the Operation Complete (bit 0) in
the event status register to be set.
Error Code
Error Message Description
-800
Operation
complete
The instrument has completed all selected pending operations in accordance
with the IEEE 488.2, 12.5.2 synchronization protocol.
Device-dependent errors
The occurrence of any error in this class shall cause the Device Dependent Error (bit 3) in
the event status register to be set.
Error Code
Error Message Description
101
Operation denied while in LOCal
state
Operation is denied because the PAT-T is in local
mode.
102
Operation denied while in OUTPut
ON state
