Can you please help me in identifying the optimised NI solution for below waveform measurement requirements –
- Test stand shall be able to analyse 8 waveform channels (i.e. product will output 8 independent waveforms, it will be input to test stand for measurement)
- Waveform can have following varying parameters –
- It will be bipolar square wave (+ and -)
- Frequency can change between 0 to 20KHz
- Amplitude can change between 0 to 150V DC
- Pulse width can change between 0 – 1mSec
- It shall be able to trigger for every channel independently. After trigger, the waveform for 1mSec shall be recorded.
- Test stand shall record timestamp for each trigger to the accuracy of 100nSec.
- It shall be possible to provide an external trigger input
- Test stand shall provide report at the end of acquisition cycle and report shall contain –
- Plot – pulse shape
- Plot – amplitude VS time , min and max readings
- Plot – frequency VS time , min and max readings
- Plot – Pulse width VS time , min and max readings
- It should be possible to add long term monitoring to record multiple acquisition session
I was thinking to build PXIe based solution using either Labview or CVI. NI cards in consideration after first brief review are PXIe-4300B, PXIe-8880, PXIe-1071.
Let me know your thoughts and all suggestions are welcome!
Also suggest if this message needs to be posted in different forum... 🙂
Thanks million ..
