Limitations of Waveform Recording

There are some limitations to perform the waveform recording as follows.
•
•
•
70
Sampling Duration value:
Limited by the size of the storage device, which must be larger than the total
file size.
Sampling Rate value:
Limited by the transfer rate of the storage device, which must be faster than
the data rate.
Missing data
When the waveform recording is in progress, missing data may occur. Then,
the CX3300 displays a message to report that missing data occurs and
continues the waveform recording as scheduled.
There are mainly two reasons which cause the missing data.
• The transfer rate of the storage device may be slower than the data rate.
• If the slide switch of Trigger for Triggered Segmentation is set to ON (Data
Logger > Recording > Trigger), it may take a long time to extract and tag
the waveform segments.
To avoid the missing data:
• Set the sampling rate slower, or reduce the number of channels.
• If the slide switch of Trigger for Triggered Segmentation has been set to
ON (Data Logger > Recording > Trigger), set it to OFF.
• If the slide switch of Trigger for Triggered Segmentation must be ON,
change Similarity Threshold (Data Logger > Recording > Similarity). Lower
similarity threshold reduces the number of the tags and comparisons
between waveform segments. It will make the time for extracting
waveform segments short.
