Introduction
This chapter contains
a
list of the HP E1440A device-dependent error
messages. In addition to them, the El440 command parser issues
syntax error messages. These syntax error messages are normally
self-explanatory,
e.g. "Number overflow", They are defined by
IEEE 488.2 and the TMSL standard.
The types of error which would occur in the HP E1440A fall into
a
narrow band within the standard VXIbus error messages allowed.
The HP E1440A is able to add an appropriate comment to an error
message, in order to provide further information. For this reason,
most error messages will appear in this list several times, but with a
different qualifying message.

+100,"Query not allowed; Cannot interrogate frequency in mode
SWEEP/LISTW
Triggered by :FREQ? command. The current frequency cannot be
interrogated while FREQ:MODE is LIST or SWEEP.
-108,"Parameter not allowed; Parameter list is too long (>50
parameters)"
Triggered by :LIST:FREQ:xxxx commands or L1ST:DWELl
command. Attempt to program one of the lists mentioned below with
more than 50 parameters.
-108,"Parameter not allowed; Sequence is too long to be stored"
Triggered by :LIST:SEQ command. Attempt to program a sequence
that needs more than 300 entries. The required number of entries is:
(the number of single points)
+
(number of ranges
*
3).
-200,"Execution error; No external reference signal detectable"
Triggered by :ROSC:SOUR command. Attempt to select reference
oscillator source EXT and no AC signal is detectable on the front
panel 'Ext Ref in' connector.
+200,"Command not allowed; Amplitude is O(fixed) for DC function"
Triggered by :VOLT command.
In
DC function, only the offset and
not the amplitude can be modified.
