Error Types
Error numbers are categorized by type as shown in
. The error codes
that can be generated by the Keysight 53147A, 53148A, and 53149A are listed in
.
The first error described in each class (for example, –100, –200, –300,–400) is a
“generic” error.
No Error
The
:SYST:ERR?
response
+0, “No error”
indicates that there are no errors in the
instrument’s error queue. The error queue is empty when every error in the queue
has been read (
:SYST:ERR?
query) or the queue was cleared by power-on or
*CLS
.
Command Error
An
<error number>
in the range [
–
100 to
–
199] indicates that an IEEE 488.2 syntax
error was detected by the instrument's parser. The occurrence of any error in this
class causes the command error bit (bit 5) in the Event Status Register to be set.
This happens when one of the following occurs:
– An IEEE 488.2 syntax error is detected by the instrument’s parser. That is, a
controller-to-instrument message was received that is in violation of the IEEE
488.2 Standard. Possible violations include a data element that violates the
instrument’s listening formats or whose type is unacceptable to the
instrument.
