Hello All,
I am seeking some guidance on a simple total power detector system that I am
putting together.
I would like to sample 8 to 16 signals at a low rate of 10 KHz with the ROACH1
and transmit the data on the 10GbE. Someone did suggest a simple USB-based ADC,
but we like the ROACH based
Good Morning,
It was very kind of some (surely independent, non-casper) soul to
share some deprecated cores necessary for casper compiles with recent
versions of Xilinx tools.
It would be nice if whomever is doing this sharing could update the
opb core mpd file to support virtex 6 for roach2,
Hi Ramesh,
When the data gets to your simulink design it will be multiplexed with
4 adc channels per adc yellow block output, so you'll have to demux
yourself or deal with the mulitplexing in your code somehow. I don't
think there's a casper block to demultiplex this for you, though there
is a
Hi Jack,
Thanks - I ended up using the concat/convert modules from Xilinx blockset to
typecast and tie the outputs of sample_and_hold modules.
Does the x64_adc accept an external 1PPS as in iADC or the 5GSPS ADC? We
normally use this signal for absolute timing of our data streams.
Cheers,
Hello All,
Can some one point me to the spead_pack block's documentation? I would like to
use this module as a simple packetiser that feeds a ten_Gbe_v2 block. Is this
possible, or am I better off using stuff from tutorial2?
Thanks!
Cheers,
Ramesh
Hi all,
Link in the thesis section for A.Parsons' thesis . Low-Frequency
Interferometry: Design, Calibration, and Analysis Towards Detecting the
Epoch of Reionization.
http://setiathome.berkeley.edu/%7Eaparsons/misc/thesis.pdf is not working.
Where can I get a copy of the same ?
Thanks!
Hi Ramesh,
There's no external connector to input a 1PPS signal, so if you need
one you'll have to wire it straight into the FPGA via GPIOs. Both
ROACH1 and 2 have some SMA GPIO inputs you could use for this purpose.
Cheers,
Jack

Roach2 sync/1PPS input options are described at :

Hi Caspersphere,
I wonder if anybody has upgraded from ROACH1 to ROACH2 and is looking to
unload a ROACH1.
