Hi all,
I have a non-astronomical comms antenna array project that does not have
detailed specs for bandwidth and number of antenna elements. I need to
build a programmable platform that I can use for multichannel sampling
and real time DSP.
Our group has considerable experience with ROACH b
Hello Karl,
How many antenna elements do you have? We've had simple two-antenna
interferometers with both F and X on a single ROACH-1. I'm still using one.
There's a tutorial on the wiki doing exactly this.
That being said, ROACH-1's biggest hassle is using CX4 Ethernet plugs,
which are finicky a

The timing and availability might be a factor, but it would be great if
"someone" had the energy to "CASPER-ise" a Xilinx RFSoC development board.
They have up to 16 ADC's that may be overkill in the sample rate
department, but it is an interesting platform. Maybe development boards
are available?
hi karl,
to add to what jack emailed about using a snap board for your
non-astronomical array:
snap has 12 ADC's on board.if you want more analog inputs, you could
plug in an ADC16 board;
then you'd have 12 + 16 = 28 inputs, up to 250 Msps each.
as jack pointed out, snap only has a pair of
I have heard, if I remember correctly, that CSIRO is doing exactly this.
If anyone has details, perhaps they could let the group know. If not, I
can probably trace the source and find out.
They are expensive chips, but maybe lower rate, lower cost versions will
be forthcoming.

Correction: by "exactly that", I mean building a radio astronomy
targeted board around the RFSoC chip, but not necessarily CASPER-ised

We are also interested in a MKID readout based on the Xilinx RFSOC. Developing
one was included as part of our recent NSF MRI proposal. If the grant is
approved I’ll let you know as our team (UCSB and Fermilab) will be starting
development in the fall.
Thanks,
Ben
