Introduction
If an error condition occurs in the signal generator, it is reported to both the front panel
display error queue and the SCPI (remote interface) error queue. These two queues are
viewed and managed separately.
NOTE When there is an unviewed message in the front panel error queue, the ERR
annunciator appears on the signal generator’s display.

Error Message Format ESG Family Signal Generators
Error Message Format
The system-defined error numbers are chosen on an enumerated (“1 of N”) basis. The
SCPI-defined error numbers and the <error_description> portions of the error query
response are displayed on the instrument.
In this chapter, an explanation is included with each error to further clarify its meaning.
The first error described in each class (for example, -400, -300, -200, -100) is a “generic”
error. In selecting the proper error number to report, more specific error codes are
preferred.
Error messages appear in the lower-left corner of the display.

ESG Family Signal Generators Error Message Types
Error Message Types
Events do not generate more than onetype of error.Forexample, an event that generates a
query error will not generate a device-specific, execution, or command error.
Query Errors (–499 to –400) indicate that the instrument’s output queue control has
detected a problem with the message exchange protocol described in IEEE 4888.2,
Chapter 6. Errors in this class set the query error bit (bit 2) in the event status register
(IEEE 488.2, section 11.5.1). These errors correspond to message exchange protocol errors
described in IEEE 488.2, 6.5. In this case:
• Either an attempt is being made to read data from the output queue when no output is
either present or pending, or
• data in the output queue has been lost.
Device Specific Errors (–399 to –300 and 201 to 702) indicate that a device operation
did not properly complete, possibly due to an abnormal hardware or firmware condition.
These codes are also used for self-test response errors. Errors in this class set the
device-specific error bit (bit 3) in the event status register (IEEE 488.2, section 11.5.1).
The <error_message> string for a positive error is not defined by SCPI. A positive error
indicates that the instrument detected an error within the GPIB system, within the
instrument’s firmware or hardware, during the transfer of block data, or during
calibration.
Execution Errors (–299 to –200) indicate that an error has been detected by the
instrument’s execution control block. Errors in this class set the execution error bit (bit 4)
in the event status register (IEEE 488.2, section 11.5.1). In this case:
• Either a <PROGRAM DATA> element following a header was evaluated by the device
as outside of its legal input range or is otherwise inconsistent with the device’s
capabilities, or
• a valid program message could not be properly executed due to some device condition.
Execution errors are reported after rounding and expression evaluation operations are
completed. Rounding a numeric data element, for example, is not reported as an execution
error.
Command Errors (–199 to –100) indicate that the instrument’s parser detected an
IEEE 488.2 syntax error. Errors in this class set the command error bit (bit 5) in the event
status register (IEEE 488.2, section 11.5.1). In this case:
• Either an IEEE 488.2 syntax error has been detected by the parser (a control-to-device
message was received that is in violation of the IEEE 488.2 standard. Possible
violations include a data element that violates device listening formats or whose type is
unacceptable to the device.), or
• an unrecognized header was received. These include incorrect device-specific headers
and incorrect or unimplemented IEEE 488.2 common commands.

ESG Family Signal Generators -499 to -400: Query Errors
-499 to -400: Query Errors
The instrument’s output queue control has detected a problem with the message exchange
protocol described in IEEE 4888.2, Chapter 6. Errors in this class set the query error bit
(bit 2) in the event status register (IEEE 488.2, section 11.5.1). These errors correspond to
message exchange protocol errors described in IEEE 488.2, 6.5.
In this case, either an attempt is being made to read data from the output queue when no
output is either present or pending, or data in the output queue has been lost.
-440 Query UNTERMINATED after indefinite response
A query was received in the same program message in which a query
requesting an indefinite response was executed (see IEEE 488.2, 6.3.7.5).
-430 Query DEADLOCKED
A condition causing a DEADLOCKED query error occurred (see
IEEE 488.2, 6.3.1.7). For example, both the input buffer and the output
buffer are full and the device cannot continue.
Query DEADLOCKED
A SCPI output queue has filled, preventing further SCPI command
execution, and there is no more room left in the corresponding SCPI input
queue to accept a query to read from the output queue. The system
automatically discards output to correct the deadlock.
-420 Query UNTERMINATED
A condition causing an UNTERMINATED query error occurred (see
IEEE 488.2, 6.3.2.2). For example, the device was addressed to talk and an
incomplete program message was received.
-410 Query INTERRUPTED
A condition causing an INTERRUPTED query error occurred (see
IEEE 488.2, 6.3.2.7). For example, a query was followed by DAB or GET
before a response was completely sent.
-400 Query Error
This is a generic query error for devices that cannot detect more specific
errors. The code indicates only that a query error as defined in IEE 488.2,
11.5.1.1.7 and 6.3 has occurred.
Error Messages 5
-399 to -300: Device-Specific Errors ESG Family Signal Generators
-399 to -300: Device-Specific Errors
Some device operations did not properly complete, possibly due to an abnormal hardware
or firmware condition. These codes are also used for self-test response errors. Errors in this
class set the device-specific error bit (bit 3) in the event status register (IEEE 488.2,
section 11.5.1).
-362 Framing error in program message
A stop bit was not detected when data was received (for example, a baud
rate mismatch).
-361 Parity error in program message
The parity bit was not correct when data was received (for example, an
incorrect parity bit on a serial port).
-360 Communication error
This is the generic communication error for devices that cannot detect the
more specific errors described for errors -361 and -362.
-350 Queue overflow
This is a specific code entered into the queue in lieu of the code that caused
the error. This message indicates that there is no more room in the queue
and an error occurred but was not recorded.
-340 Calibration failed
The device has detected a failure during its calibration procedure.
-330 Self-test failed
The device has detected a failure during its self-test procedure.

An error has been detected by the instrument’s execution control block. Errors in this class
set the execution error bit (bit 4) in the event status register (IEEE 488.2, section 11.5.1).
In this case:
• Either a <PROGRAM DATA> element following a header was evaluated by the device
as outside of its legal input range or is otherwise inconsistent with the device’s
capabilities, or
• a valid program message could not be properly executed due to some device condition.
Execution errors are reported after rounding and expression evaluation operations are

error.
-294 Incompatible type

-291 Out of memory
A downloaded program required more memory than was available in the
instrument.
-290 Memory use error

-281 Cannot create program
An attempt to create a program was unsuccessful. This may be due to
insufficient memory.
-280 Program error
