Hello All, I am trying to run the tutorial 3 spectrometer on a ROACH + 1x_3GSPS_iADC. I used the bof file provided by casper as well as our own bof file compiled here (on ubuntu) using the simulink model from casper after replacing the pfb and fft blocks from our 'local' library.
In both cases I got a strange symmetric spectrum ( http://www.das.uchile.cl/~rfinger/ROACH/tut3_1.png ) which doesn't change to much when a test tone is applied. The iADC clock was 800MHz, 0dBm, provided by a valontech 5007 synthesizer, and the test tone was 100/200 MHz, 0dBm. After a few integration periods I get a 'timeout' error, and a blank window in the spectrometer.py application. Does anyone got the same problem? Thanks, Ricardo. -- Ricardo Finger Camus Electrical Engineer Astronomy Department University of Chile Of: 56(2)9771119 Casilla 36-D, Santiago. http://www.das.uchile.cl/lab_mwl/
