Alphabetical Order - Agilent Technologies E4991A Service Manual

Messages
Additional standards needed
Messages showing the status of the E4991A are displayed in the lower-left area of the
E4991A LCD screen. These messages include error messages that occur during the
execution of GPIB commands and others that indicate the internal status of the equipment.
Error messages are indicated following the character string "[Err]" and can be read out by a
GPIB command. Other kinds of messages are indicated without the "[Err]" character string
and cannot be read out by a GPIB command. This section explains the meaning of each
message and how to resolve the problem it indicates.

Alphabetical Order

Errors with negative error numbers are basically general errors for GPIB instruments
defined by IEEE488.2. On the other hand, errors with positive error numbers have been
defined specifically for the E4991A.
A
6 Additional standards needed
Before completing data measurement that requires calculation of the calibration
coefficient, a GPIB command is sent to turn the calibration function On. For example,
when only measurement of the Open Standard and Short Standard, but not the Load
Standard, of the calibration kit has been completed, the SENS:CORR1:COLL:SAVE
command is attempted in order to set the calibration function On.
Measure all of the necessary calibration data.

-168 Block data not allowed
Block data ia received at a position where the E4991A cannot allow a block data element.

During measurement of the necessary calibration/fixture compensation data, or during
and after the calculation of calibration/fixture compensation coefficients (with
calibration function turned On), the settings of calibration/fixture compensation
acquired data points (

and/or the calibration/fixture compensation function have been invalidated.
While the calibration/fixture compensation acquired data point setting is in the
user-defined point condition (
Sweep Parameter, Measurement Points, and Sweep Type) has been altered during
measurement of the necessary calibration/fixture compensation data, or during and
after the calculation of calibration/fixture compensation coefficients (with the
