Error Messages
Error Messages in Alphabetical Order
SEQUENCE, capability when you are building a sequence. Attempting to use this softkey at any other time
returns an error message and no action is taken.
8703 SOURCE PARAMETERS CHANGED. Error Number 61. Some of the stimulus parameters of the instrument
state have been changed, because you have turned correction on. A calibration set for the current
measurement parameter was found and activated. The instrument state was updated to match the stimulus
parameters of the calibration state.
GPIB COPY IN PROGRESS, ABORT WITH LOCAL. Error Number 169. An GPIB copy was already in progress when
you requested the GPIB for another function. To abort the first copy, press Local, otherwise the GPIB is
unavailable until the first copy is completed.
IF BW KEY DISABLED, EDIT LIST MODE TBL. Information Message. When list IF bandwidth has been enabled
and swept list mode is on, you will not be able to change the IF bandwidth using the IF BW, key. To change
the IF bandwidth, edit the swept list table.
ILLEGAL UNIT OR VOLUME NUMBER. Error Number 46. The disk unit or volume number set in the analyzer is
not valid. Refer to the disk drive operating manual.
INIT DISK removes all data from disk. Information Message. Continuing with the initialize operation will
destroy any data currently on the disk.
INITIALIZATION FAILED. Error Number 47. The disk initialization failed, probably because the disk is damaged.
INSTRUMENT STATE MEMORY CLEARED. Error Number 56. All instrument state registers have been cleared
from memory along with any saved calibration data, memory traces, and calibration kit definitions.
Additionally, all user-settable selections (such as GPIB addresses) are set to their defaults.
INSUFFICIENT MEMORY. Error Number 51. Your last front panel or GPIB request could not be implemented
due to insufficient memory space. In some cases, this is a fatal error from which you can escape only by
presetting the instrument.
INSUFFICIENT MEMORY FOR PRINT/PLOT. Error Number 168. There is not enough memory available for the
print or plot function. Increase the available memory by changing or eliminating a memory-intensive
operation such as reducing the number of points in the sweep.
INSUFFICIENT SIGNAL FOR BIAS ADJUST. Information Message. Autobias failed due to lack of enough laser
power to the modulator. Check that the jumper is not removed. Contact your nearest Agilent office if this
message persists.
INSUFFICIENT MEMORY, PWR MTR CAL OFF. Error Number 154. There is not enough memory space for the
power meter calibration array. Increase the available memory by clearing one or more save/recall registers,
or by reducing the number of points.
INVALID KEY. Error Number 2. An invalid key was attempted; there may be a possible hardware failure.
ISOL AVERAGES < SWP AVERAGES. Error Number 223. The isolation averages are less than the instrument
sweep averages. Increase the isolation averages to be equal to or greater than instrument sweep averages.
This error can only occur when instrument averaging is turned on.
LASER TEMPERATURE LOOP OPEN. Error Number 219. The laser temperature is unstable. (This message may
appear for the first few minutes when the analyzer is powered up.) Cycle the analyzer power and allow a
warm-up time of two hours, then press any key. If the message persists, contact your nearest Agilent office.
