Error messages
Order of Alphabet
C. Error Messages
An equation data element was received at where the 4294A did not accept any equation
data elements.
-170 Expression error
An error not included in error numbers between -171 and -179 occurred during the syntax
analysis of equation data.
F
-257 FILE NAME ERROR
There was an error in the filename and, as a result, the command was not executed
correctly.
This message is displayed, for example, when you attempt to copy a file using the same
filename.
-256 File name not found
The specified filename was not found and, as a result, the command was not executed
correctly. This message is displayed, for example, when you attempt to read/write a file
that does not exist on the disk.
143 FLOATING POINT ERROR OCCURED
Due to the execution of an application inside the instrument for inappropriate data sent
from outside the instrument, an error for floating point operations occurred inside the
instrument. The result of the operation may be incorrect. Contact your local Agilent
Technologies sales office or the company you purchased this instrument from.
85 FORMAT NOT VALID FOR COMPLEX MEASUREMENT
When COMPLEX Z-Y (i.e., complex parameter measurement) was selected as a
measurement parameter, you attempted to select a display format not available for the
measurement parameter, for example, the linear scale format (FMT LINY command) and,
as a result, the command was ignored. When COMPLEX Z-Y is selected as a measurement
parameter, set the display format to the complex plane display format (command: FMT
COMP) or the polar coordinates display format (command: FMT
POLA).
86 FORMAT NOT VALID FOR SCALOR MEASUREMENT
When a measurement parameter other than COMPLEX Z-Y (i.e., scalar parameter
measurement) was selected, you attempted to select a display format not available for the
measurement parameter, for example, the complex plane display format (command: FMT
COMP) and, as a result, the command was ignored. When a measurement parameter other
than COMPLEX Z-Y is selected, select a display format from the linear scale format
(command: FMT LINY), the log scale format (command: FMT LOGY), or the percent
format (command: FMT PERC).
131 FREQUENCY SWEEP ONLY
When a sweep parameter other than the frequency was specified, you attempted to execute
an equivalent circuit analysis command (CALECPARA and so on). You can execute the
equivalent circuit analysis only when the sweep parameter is the frequency.
