Are there any considerations to enhance the bandwidth for recording and streaming? It feels like the current setup necessitates investing in a more expensive Digilent device for higher performance. Expanding the digitizer capability of AD3 to fully utilize USB 2.0 bandwidth could be a valuable improvement. Why can't Digilent just open source the dang thing if it is for learning?

Is there any way you could add support for 20 msps at 8 bits/channel? Then AD3 could be used for the vhs-decode project.

Just to clarify, record steaming at 10 MHz (on one channel) means 20 msps of 16-bit data?

I've recently embarked on a project to digitize my family's VHS tapes, aiming for the best possible image quality. In my quest for an optimal solution, I came across the vhs-decode project, which involves tapping a test point inside the VCR and using recommended devices like a hacked capture card or the Domesday Duplicator to capture the "VHS FM" signal to a PC. However, I've noticed that some of these devices have deficiencies, prompting users to design their own PCB, such as the SMIRF. This led me to explore alternative devices, and that's when I discovered the AD3. According to user feedback, storing data from VHS is most effective at 20 msps with 8-bit resolution. Additionally, users suggest that the digitizer should have a low-frequency response down to 1 kHz, a feature lacking in many devices recommended on the vhs-decode wiki. So, my questions are: Can the AD3 handle the throughput of a 20 msps 8-bit signal over USB? And does it have the capability to digitize frequencies down to 1 kHz?
