NI-SCOPE (English | Japanese) |
Trigger delay, which is specified in seconds, is achieved on the NI 5114/5152/5153/5154 by adding the appropriate number of posttrigger samples to the record while keeping the allocated onboard memory equal to the record size you request. NI-SCOPE then corrects the trigger time by the delay you specify. To determine the maximum delay for a particular actual sample rate, use the following formula:
Max trigger delay in seconds = [(235 – 1) – requested posttrigger samples] × (1/actual sample rate)

Note The maximum trigger delay changes when you use an external sample clock, and when you sample at rates other than full rate while using the internal sample clock. |
