Hello,
I am trying to find a high sample rate analog input data acquisition tool. My setup will measure voltage between 0-1V at a high sample rate of >1MS/s. From NI I've come across NI 9223 module but not much else. Measurement resolution is >12 bits.
What options do I have? Is there something I'm not considering? I've also found another developers DAQ capable of 8MS/s continuous input at resolution of 12 bits. (https://www.mccdaq.com/usb-data-acquisition/USB-2020.aspx)
I would appreciate your comments and feedback.

Needed input impedances? Frequency range?
Number of channels?
I have a PXI system with flex resolution 5922 (up to 15MHz, up to > 20bit) and a (NI-) PXI FPGA with 4channel 1GSPS @16 bit ... still working on my FPGA skills .. checking the real resolution is on my list
Never checked, but the weight in gold might be the same 😄
Stay with NI to easely run it with LabVIEW .. or look for a USB scope?

There are several USB 2.0, PCI-Express DAQ cards and PXI-Express DAQ cards that will sample at greater than 1MS/s. Here are a few examples.
PCIe-6351 : 1.25MS/s
USB-6361 or PCIe-6361 or PXIe-6361 : 2MS/s
USB-6363 or PCIe-6363 or PXIe-6363 : 2MS/s
USB-6366 or PXIe-6366 : 2MS/s/channel, this module will sample 8 differential analog inputs simultaneously.
I don't know how many channels you need to sample but this list should get you started. You can look for Multifunction I/O devices and find many more.
