Appendix 2 Relationship between the Main Channel Sample Rate, Sub Channel Data Update Rate, and Acquisition Memory Writing Rate
CAN Bus Monitor Module, CAN & LIN Bus Monitor Module, and SENT
Monitor Moudule
Rate at Which Data Is Written to the Acquisition Memory
Number of Sub Channels Used
Sub Channel Sample Rate
(Data Update Rate)
Main Channel Sample
Rate Setting (S/s)
If you set the sample rate (the main channel sample rate setting) of the DL850E/DL850VE to a rate
that exceeds the sub channel data update rate, all data within the sub channel data update interval
will be the same.
