Hello, I have a process where we are using several of the AD2 devices to capture a few uS of information on a trigger (T1) event generated by a Digital Discovery board. The Digital Discovery is looking for an external Logic trigger input, and then executes a pattern which pulses external equipment as well as these AD2 devices. The rate at which the external Logic trigger is occurring is fast (2mS or so), however, we are using a custom Java interface to pull the latest buffer data from the AD2s and this occurs on the order of 100mS. The problem is that when the first Device's buffer is pulled it does not necessarily correspond to the same event captured in the next Device's buffer when it is pulled. It is very useful for us to make sure that the buffer we pull across all devices, is from the same trigger event. This will help us paint an accurate picture of what is going on. The equipment cannot run slower and we cannot speed the buffer pulls to under the 2mS, due to data processing constraints. Is there a way through configuring the AD2 (HoldOff / Buffer Stop, etc) or the DigitalDiscovery Pattern output that we may be able to achieve synchronous captures on the order of 100mS while the remainder of the triggers controlling the equipment continues to run at 2mS?
