Limitations of Waveform Recording
There are some limitations to perform the waveform recording as follows.
•
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.
