No.50 - 199: Generation of a reason why a function cannot be executed
101 All traces in FIX state  Waveforms cannot be re-written, because all traces have been set 
to FIX.
102 Sweep stopped  Sweep was stopped, because all traces were set to FIX during the 
sweep.
103 No data in active trace  An attempt was made to execute analysis functions when there 
was no data in an active trace. An attempt was made to execute the 
EDFA-NF analysis function or the WDM analysis function (DUAL 
TRACE = ON) when there was no data in traces A and B.
108 Marker setting out of range  An attempt was made to execute the analysis function between 
markers in the state where both line marker 1 and line marker 2 
were set outside the measurement range.
109 Auto sweep failed  Although the AUTO sweep started, the sweep stopped because 
optimum conditions were not found.
110 No data between line markers An attempt was made to execute the analysis function in a state 
where there was no data in the line markers of an active trace.
111 <G=MKR FIT> failed Trace G cannot write fitting curve because numbers of data is not 
sufficient during <G=MKR FIT>.
120 USB storage not found  USB storage medium not inserted.
121 USB storage not initialized SUB storage not initialized.
122 USB storage write protected  The USB storage device is write protected.
123 File not found The specified file cannot be read because it has not been found. Or, 
the file does not exist on the disk.
124 Improper directory name Directory cannot be created because the name is not valid. 
125 Improper file name  A file cannot be saved due to an incorrect file name.
126 Directory already exists Directory cannot be created because a directory of the same name 
already exists.
127 File already exists File cannot be created because a file of the same name already 
exists.
128 A write-protected file  The file cannot be re-written or deleted because its property has 
been set to READ ONLY.
129 Storage full  The file cannot be saved, because the hard disk or the USB storage 
device is full.
130 Directory full No files can be created because the directory area is full.
131 No data  There was no data to be saved, although an attempt was made to 
save the file.
132 Trace file not found The file cannot be read because it is not a waveform file.
133 Program file not found The file cannot be read because it is not a program file.
134 Data file not found  The file cannot be read because it is not a data file.
135 Setting file not found  The file cannot be read because it is not a settings file.
138 Copy denied for invalid file name The file copy cannot be executed because the “copy from” file and 
the “copy to” file have the same name.
139 Unsuitable Write item Write item is not appropriate.
140 Paste denied for lack of line space The paste operation cannot be executed during the editing of 
programs because the number of blank rows is not sufficient.
141 Denied for limit of lines maximum It is not possible to execute a merge during the editing of programs 
because the merged result would exceed the maximum number of 
rows.
142 WL calibration failed  Calibration cannot be executed because the level of a light source 
is not sufficient during the wavelength calibration or because 
wavelength deviations exceed the calibration range.
143 Optical alignment failed Alignment adjustment cannot be executed because the level of a 
light source is not sufficient during the alignment adjustment.
147 RBW calibration failed. (Power) Rms resolution calibration cannot be executed because the light 
source level is too low.
