Error messages
Error number: 104
104 Save error
When saving a file, anomalies in the storage media are detected. For example, when you
attempt to save a file on a floppy disk, there is not enough space on the disk.
Make sure there is enough space on the floppy disk.
105 Recall error
An error occurs while reading out (recalling) a file. For example, you attempt to read out a
file with invalid contents (such as an instrument setting file with extension “.sta”, which is
saved by using an instrument other than the 4287A).
Make sure that the contents of the file are valid.
106 Invalid File Name
When executing the save/recall file command, a file name string is invalid. For example,
when executing the save command, no extension for the file is specified.
Specify a valid file name.
This error also occurs if the floppy disk has not been correctly set into the drive or if the
disk is write-protected when you attempt to save a file onto the disk.

entered the correct signal or you did not enter any signal, the instrument needs adjustment
or repair. Contact your local Agilent Technologies sales office or the company you
purchased this instrument from.
