Hi Dale
The CASPER packetised correlator (that PAPER/HERA/KAT-7/MeerKAT etc are all
using) would scale simply to your needs. You could easily build it out of
ROACH2s or SKARABs at your scales. It would be a bit more expensive than the
SWARM-type solution, in that it'd need additional hardware
Hi Dale,
I’ll offer a few bullets on SWARM, the new SMA system.
1. SWARM is all open source and shared via CASPER and you are welcome to use
it as is, or develop it further to adapt it to a new application, indeed it
would be very pleasing to see the design used in some other instrument.
2.
hi dale,
i'd be happy to talk to you on the phone about pros and cons of different
options if you'd like.
jack also told me a bit about your plans - he'd be good at providiing
advise on the different options..

Dear Jonathan (and the rest of the CASPER list, in case anyone has
additional comments),
I am looking into a new project that would require processing around 2 GHz
of bandwidth on of-order 10 (but more than 8) dual-polarization antennas.
Our science case calls for at least 4096 frequency
Dear all,
As suggested by Rick Raffanti (personal communication), we have replaced
the onboard 50 MHz oscillator chip with a pin-compatible 64 MHz oscillator
chip (CWX813-064.0M from Connor-Winfield). The ADC board was tested at 64
MHz clocking with correlator/beamformer design on ROACH-1 and its
5 matches
