SCXI-1600 Sample Clock Problem - Large Lag

[RVallieu]

I notice the property of Threshold - I thought that setting my own threshold might be a solution, but I can not find the property on the list for setting the threshold.  Actually I found it using a search, but when I tried to select it, it would not select.

Hi Ryan,

The custom threshold property will not improve performance as it will be setting a number of samples in the onboard memory necessary to send data over the bus. Since the previous setting, "Onboard Memory Not Empty," did not improve the situation, setting a custom threshold will not either. In fact, it should decrease performance (in this application case) because the threshold will be higher than 2, the minimum number of samples necessary to send data over the bus and also the minimum number of samples that setting "Onboard Memory Not Empty" will send. "Onboard Memory Not Empty" will send data as frequently as it gets it whereas Custom Threshold will wait until the number of samples you specify (minimum 2) is available.

Makes sense.  Thanks for the help.
