Scope memory depth?

[MrBill]

Hi, new to redpitaya and would to know about the memory depth possibilities. I did see a 16k memory in the wiki page. I am interested in deep mega to giga applications. With the SD card, USB or ESata interfaces could this be possible?

Hi Bill,

There are a few solutions that target larger storage for samples, melko's Non-stop data write on a storage device, the latest additions to the original Red Pitaya ecosystem, and my own project.

The big question is, what is your desired sample rate ? At the highest rates, there is simply no interface on the Red Pitaya to carry the full stream off-device in real time.

zynq provides a SATA interface from what i see...

could you store the samples and access one single SATA HDD or SATA SSD via a standard Linux block device interface?
...one single SATA I (1.5 Gbps), SATA II (3 Gbps) and SATA III (6 Gbps) host port.

The example you linked uses the GTX multi gigabit transcievers, which are only included in some of the larger ZYNQ models, but not in the 7z010 of the Red Pitaya.

There are sata connectors on the Red Pitaya, but they are not sata interfaces. The connectors have only been used because they are common (ie widely available and inexpensive) and suitable for high bandwidth transmissions.
