Error Codes and Warnings
This section gives a list of error codes that the application displays and their
descriptions.
Table 36. Error Code descriptions
Error Codes Error Message Description Possible Solutions
Sequencer Errors
E101 Error importing waveform from
the oscilloscope The application is trying to import the
waveform(s) from the selected
source(s), but is not able to import the
waveform to the application
Make sure that the application settings are
the
same as the selected oscilloscope
channels. Check the probe connections
and the compliance test fixture connections
for the live signal(s)
E102 Error in accessing .tsv file This error occurs whenever .tsv file is
selected as the source file and this file
is not a valid .tsv file
Check whether the file name extension is
.tsv. The selected .tsv source file may be
corrupted. Try running the application with
a different tsv file
Try generating the .tsv file using .tsv File
Generator utility that is available in the
Utilities menu
E103 Mismatch in the .tsv file format The .tsv file should match the file
structure mentioned in Reference
section of this help. For Low and Full
Speed signals, each data record
should have three values (Timestamp,
D+, D–). For a High Speed .tsv file, the
file should have two columns (Time,
Diff). Use a valid file
E104 Record length is more. Set the
record length to less than
XXXXXX data points
The record length is too high for the
waveform Click the "Horiz" button or "Horiz/Acq"
Menu from the oscilloscope UI. Go to
Horizontal tab and decrease the record
length
