12 févr. 2024 · Yes I wasn’t clear in my first post. I would like to be able to get pretrigger samples from analog Input channels on 2 NI-6133 cards in a PXI-1042Q. From your attached example I learned that it is easy to do it for channels in the same device. I searched a bit in the Labview examples and I found this vi I could try to adapt to my. 16 août 2024 · Solved: Hi, I am using a PCI-6602 board to record the times of incoming pulses. I'd like to add a trigger line so that my program will keep the data. 13 juil. 2016 · I'm doing a project where I'm recording the postrigger and pretrigger of a signal. I can record postrigger samples continously. My problem is that I would like to recording prettrigger samples continously but I can't do it with Labview. Any suggests will be helpful. 11 juil. 2024 · You can configure the 4472 to use an analog trigger to start acquring data, and to take pretrigger samples the same way that you configure an E series board using Traditional NI-DAQ calls (DAQmx also supports E series board). 3 août 2017 · To test my triggering, I have set up a simple program which generates an Analogue Voltage task, sets the timing to Finite Samples with an appropriate sampling rate, provides the trigger source and rising edge, reads/displays the data, and finally stops and clears the tasks. 21 juil. 2024 · In a pretriggered acquisition, the A/D conversions are initiated with a software function call. NI-DAQmx stores the digitized data in computer memory in a circular buffering scheme, replacing the oldest points in the buffer with the new samples. Once the trigger signal is received, a specified number of points before and after the trigger are. HRAM may return an incomplete set of failures if HRAM is configured to use pretrigger samples and capture failures only: If the HRAM settings within the Digital Pattern Editor are configured to have the Cycles to Capture to Failures Only and the Pretrigger Cycles is greater than 0, the failures captured may be different than the requested. 26 févr. 2024 · Under DAQmx, a trigger is a once-per-capture signal marking a single point time, most often the start of acquisition. A sample clock happens repeatedly within a capture to cause samples to be acquired and accumulated. 11 mars 2024 · NI-DAQmx. Provides support for NI data acquisition and signal conditioning devices.
