C. Error Messages

When the band width function was off, you attempted to execute a command to search the

cutoff point on the trace (WIDSIN or WIDSOUT) and, as a result, the command was

ignored. Before executing the cutoff point search of the band width function, turn on the

band width function (command: WIDT ON).

-330 Self-test failed

The result of the self-test was a failure. Contact your local Agilent Technologies sales

office or service center, or refer to the service manual.

-221 Setting conflict

A program data element complying with the syntax standard was analyzed but the 4294A

could not execute it at present.

-150 String data error

An error not included in error numbers between -151 and -159 occurred during the syntax

analysis of a string data element.

-158 String data not allowed

A string data element was received at where the 4294A did not accept any string data

elements.

-130 Suffix error

A suffix error.

An error other than -131 to -139 occurred in the notation of a suffix.

-138 Suffix not allowed

A suffix is added to a numeric value element to which no suffix can be added.

-134 Suffix too long

The suffix is too long.

The suffix contains the notation of 12 characters or more. (Refer to IEEE488.2,7.7.3.4.)

-102 Syntax error

There is a command or data type that cannot be recognized. For example, though the

4294A did not accept any strings, a string was received.

-310 System error

One of “system errors” defined for the 4294A occurred.

87 THETA MEASUREMENT NOT SELECTED

When the setting of the phase (q) was not active as a measurement parameter, you

attempted to execute a command to set the phase unit (PHAU DEG or PHAU RAD) or a

command to set the phase expansion display (EXPP ON or EXPP OFF) and, as a result, the

command was ignored. The active status of the phase (θ) setting means:

•|Z|-θ or |Y|-θ is selected as a measurement parameter and trace B is active.

• COMPLEX Z-Y is selected as a measurement parameter, and the display format is

PLOAR (polar coordinates display format) for the selected active trace.
