Logic analyzer spec

General Topics about DSLogic Pro hardware
Hi, I am shopping for a faster logic analyzer than saleae logic pro 16, which can sample 4 channels at 500 samples/s through US 3.0. When you say 4 channels @ 400 MHz, do you mean that you are sampling up to 4 channels (can change from GUI?) at 400 MHz, or do you mean that you can monitor a clock ticking at 400 MHz (which would require sampling faster than 800 MHz)?

Also, the spec says that the analog input BW is 50 MHz. Does this limitation apply to the digital signal as well (in which case, what is the point of sampling faster than 100 MHz)?

Thank you for any clarification.

4 channels @ 400 MHz means that you can sample up to 4 channels (will be changed automatically when you set the sample rate) at 400 MHz.
The bandwidth is the -3db frequency at analog signal view. For a digital signal, we only focus on low or high. So actually, DSLogic can sample up to 100MHz digital signal @ 400M sample rate.

Hope this can help you!
