[Discuss-gnuradio] USRP Input Calibration / CIC Filter Response

Hi, I'm trying to calibrate the USRP so I can get true dBm readings out of it. I'm using an LFRX card with 16 decimation and a center frequency of 2 MHz so I can look at the range from DC - 4 MHz. I hooked up a signal generator and swept it through the DC - 4 MHz range at 100 kHz intervals and gen
