Error messages
Error number: 88
• COMPLEX Z-Y is selected as a measurement parameter, and the display format is
PLOAR (polar coordinates display format) for the selected active trace.
Before executing a command to set the phase unit or a command to set the phase expansion
display, perform one of the above settings.
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).
89 PERCENT FORMAT NOT SELECTED
When the percent format was not selected as the display format, you attempted to select
delta % as the data operation setting (you sent the MATH DELP command). If you want to
select delta % as the data operation setting, the percent format (command: FMT PERC)
must have been selected as the display format.
90 SCALE PARAMETER NOT VALID
You attempted to set a display scale not settable for the selected display format and, as a
result, the command was ignored. For example, when the log scale (command: FMT
LOGY) was selected as the display format, you attempted to perform the SCALE/DIV
setting (command: SCAL <value>).
91 DATA AND MEMORY TRACE NOT DISPLAYED
When both of the data trace and the memory trace were not displayed, you attempted to
change the setting of the data & memory couple (command: SCAC ON or SCAC OFF). To
change the setting of the data & memory couple, first, display both of the data trace and the
memory trace (command: DISP DATM).
93 DATA TRACE NOT DISPLAYED
When the data trace was not displayed, you attempted to set the function that needed the
display of the data trace and, as a result, the command was ignored. For example, a
command (MKRO DATA or SCAF DATA) corresponding to the MARKER ON [DATA] key
or the SCALE FOR [DATA] key was sent. Before setting the function that needs the
display of the data trace, display the data trace (command: DISP DATA or DISP DATM).
94 MEMORY TRACE NOT DISPLAYED
When the memory trace was not displayed, you attempted to set the function that needed
the display of the memory trace and, as a result, the command was ignored. For example, a
command (MKRO MEMO or SCAF MEMO) corresponding to the MARKER ON
[MEMORY] key display or the SCALE FOR [MEMO] key display was sent. Before
setting the function that needs the display of the memory trace, display the memory trace
(command: DISP MEMO or DISP DATM).
98 NO ACTIVE MARKER
When the marker was not displayed, you attempted to execute the marker moving
(Marker?) function and, as a result, the command was ignored. For example, when the
marker was not displayed, a command corresponding to the MKR?START key
(MKRSTAR) was sent. Before executing the marker moving function, display the marker
(command: MKR ON).
99 DELTA MARKER OFF
