Callum,
Here is a configuration that may work for you.
- Setup your update line with the 20MHz timebase.
- Setup your axis line with the 100kHz timebase.
- Arm start these two counters.
- Export via RTSI the 100kHz to the 6536 and use it as the sample clock to over sample by 5x.
- Use the Decimate(continuous) VI to get your data back to 20kHz sampled data.
Regards,
Dustin D
