Hi,
Just wanted to say that I managed to run all 3 ADC chips of the SNAP board
in parallel at 960 MSps. The setup worked reliably for approximately an
hour. I managed to make some sort of 3-channel spectrum analyzer.
The board takes input at SMATP1, SMATP5 and SMATP9. PFB consists of the
Hi,
Thank you very much for your replies. The temperature being a possible
cause is quite interesting.
Actually for our project we need 250 MSps on 12 channels. I am still in the
learning process so I set myself a mini project and I thought I'll program
the SNAP just to output a spectrum. I have
Hi Nitish,
The reason that the ADC worked the first time *might* be temperature. When
parts are cooler, they often can run at higher speeds. It might be that
the first time you ran it was before the board got warm, and that's why it
worked. Then later the board had warmed up, which changes
hi nitish,
i don't think there's an easy way to make all three adc's work at 1 Gsps.
i think one of the adc's works reliably at 1 Gsps.
the other two work reliably around 950 Msps. (i'm not sure about this
number).
if 950 Msps isn't enough for your application,
you could play around with the
Hi,
I read from the SNAP wiki page that we can operate the SNAP board ADCs at
1GSps with 3 channels of input. So, I modified the CASPER SNAP tutorial 3
to make the ADC work at 1GSps to obtain a 1 channel spectrometer with a
spectrum of 500 MHz. First I modified the SNAP User IP Clock Rate to 250
