Error Messages in Alphabetical Order
Ensure that the disk drive address recognized by the analyzer matches the GPIB address set on the disk
drive itself.
DISK READ/WRITE ERROR. Error Number 189. There may be a problem with your disk. Try a new floppy disk. If
a new floppy disk does not eliminate the error, suspect hardware problems.
DISK WEAR - REPLACE DISK SOON. Error Number 49. Cumulative use of the disk is approaching the maximum.
Copy files as necessary using an external controller. If no controller is available, load instrument states
from the old disk and store them to a newly initialized disk using the save/recall features of the analyzer.
Discard the old disk.
DUPLICATING TO THIS SEQUENCE NOT ALLOWED. Error Number 125. A sequence cannot be duplicated to
itself.
EXCEEDED 7 STANDARDS PER CLASS. Error Number 72. When modifying calibration kits, you can define a
maximum of seven standards for any class.
FACTORY CAL ARRAY X IS NOT FOUND. Information Message. Improper firmware usage. The analyzer needs
to be recalibrated if this message persists. The results of lightwave measurements will be erroneous.
Contact your nearest Agilent office if this message persists.
FILE NOT COMPATIBLE WITH INSTRUMENT. Information Message. You cannot recall user graphics that had
been saved on an earlier model of analyzer with a monochrome display. These files cannot be used with the
analyzer.
FILE NOT FOUND. Error Number 192. The requested file was not found on the current disk medium.
FILE NOT FOUND OR WRONG TYPE. Error Number 197. During a recall operation, either the file was not found
or the type of file was not an instrument state file.
FIRST CHARACTER MUST BE A LETTER. Error Number 42. The first character of a disk file title or an internal
save register title must be an alpha character.
FORMAT NOT VALID FOR MEASUREMENT. Error Number 75. Conversion measurements (Z or Y reflection and
transmission) are not valid with Smith chart and SWR formats.
FORMATTING DATA. Information Message. The list information is being processed for a list data output to a
copy device and stored in the copy spool buffer. During this time, the analyzer's resources are dedicated to
this task (which takes less than a few seconds).
FUNCTION NOT AVAILABLE. Error Number 202. The function you requested over GPIB is not available on the
current instrument.
FUNCTION NOT VALID. Error Number 14. The function you requested is incompatible with the current
instrument state.
FUNCTION NOT VALID DURING MOD SEQUENCE. Error Number 131. You cannot perform sequencing operations
while a sequence is being modified.
FUNCTION NOT VALID FOR INTERNAL MEMORY. Error Number 201. The function you selected only works with
disk files.
FUNCTION ONLY VALID DURING MOD SEQUENCE. Error Number 163. You can only use the GOSUB
