Greetings,
Are you needing to acquire each signal at 150kS/s-300kS/s (1.05MS/s-2.1MS/s aggregate rate) or are you needing an aggregate sampling rate for all 7 channels of 150kS/s-300kS/s (21.4kS/s-42.9kS/s per channel)?
If you are needing 150kS/s-300kS/s for each channel, then you will probably need two analog input devices. We have analog input devices that can acquire 5 MS/s per channel (PCI-6110) but it only has 4 analog input channels. So, two NI 6110s would give you 8 analog input channels that can acquire at 5 MS/s per channel.
If you are only needing an aggregate sampling rate for all 7 channels of 150kS/s-300kS/s (21.4kS/s-42.9kS/s per channel), then we have multiple devices that would work. For instance, the NI 6052E is a 16-bit, 16 channel analog
input device that can acquire at 333 kS/s (47.6 kS/s per channel for 7 channels) and the NI 6070E is a 12-bit device, 16 channel analog input device that can acquire at 1.25 MS/s (178.6 kS/s per channel for 7 channels).
I've linked the devices below that I've referenced so you can take a look at them. Let me know if you have any additional questions about any of this.
