Order of Alphabet
L
132 LIST SWEEP ONLY
When a sweep type other than the list sweep was specified, you attempted to execute a
command to specify all segments (entire sweep range) as the search range setting
(SEARNG FULL) or a command to specify a certain segment as the search target
(SEGMNUM <value>) and, as a result, the command was ignored. Before setting the
search range for the list sweep, specify the list sweep as the sweep type (command: SWPT
LIST).
124 LIST TABLE EMPTY OR INSUFFICIENT TABLE
When the list sweep table was empty or insufficient, you attempted to select LIST as the
sweep type (command: SWPT
LIST) and, as a result, the command was ignored. Before
selecting the list sweep as the sweep type, set the list sweep table correctly.
M
-250 MASS STORAGE ERROR
A mass storage error occurred.
A mass storage error other than -257 occurred.
88 MATH FUNCTION NOT VALID FOR PERCENT FORMAT
When the percent format was selected as the display format, you attempted to change the
setting of data operations. In the percent format, data operations are fixed to delta %
(command: MATH DELP), and therefore, you cannot change the data operation setting to
DATA (command: MATH DATA), DATA-MEM (command: MATH
DMNM), or
DATA/MEM (command: MATH DDVM).
105 MEASUREMENT PARAMETER NOT FOR ANALYSIS
When a measurement parameter other than |Z|-q was set, you attempted to execute a
waveform analysis command (for example, OUTPCERR?) and, as a result, the command
was ignored. Before executing a waveform analysis command, set the measurement
parameter to |Z|-θ (command: MEAS IMPH).
-258 Media protected
You attempted to save/delete data to/from the storage device or initialize the media, but the
media was write-protected, and, as a result, the operation could not be executed. This
message is displayed, for example, when you have specified the floppy disk drive as the
storage device and a floppy disk is write-protected. If necessary, disable the
write-protection for the floppy disk.
-311 Memory error
An error was detected in the memory of the 4294A.
34 MEMORY TRACE NOT ACTIVE
Though no data was stored in the memory trace, you attempted to execute a command
(DISP MEMO, DMNM, and so on) that used the memory trace. The command was invalid.
First, use the DATMEM command and store data in the memory trace.
94 MEMORY TRACE NOT DISPLAYED
