My goal is to implement signal conditioning algorithm. Input is the tuned frequency, output is the optimal gain settings to utilize the full range of ADCs with saturation below acceptable threshold. I would like to ask for clarification regarding the over-count value. From a thread "usrp: rssi/clipping indicator, data glitches" http://www.mail-archive.com/removed_email_address@... http://www.mail-archive.com/removed_email_address@... I see the over-count value can be obtained like urx->_read_fpga_reg(5 + which_adc) The returned value 32bit: The lower 16 bits has the RSSI value, and the upper 16 bits has the over-count value. 1) How to reset the over-count value? urx->_write_fpga_reg (5 + which_adc, 0) 2) The over-count value counts the clipped samples. What is the period under test? Is it number of clipped samples since reset? 3) What happens when the over-count value reaches its max (2^16)? Does it stays at max? -- View this message in context: http://www.nabble.com/USRP1-signal-conditioning-tp... Sent from the GnuRadio mailing list archive at Nabble.com.
