Christian Daniel -- maintech GmbH cd at maintech.de-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys, I measured the sensitivity of our OsmoSDR. For that I did the following commands: tuner.init! tuner.freq=465000000 tuner.dc_calib! tuner.dc_table! tuner.gain=6,9,9,2,15,15 tuner.iqofs=43,27,0,0 I did the measurements on no-so-even frequencies to avoid any lines in the sprectrum. I increased the power from my signal generator until a SNR of 10dB as achieved. The RX was tuned 100kHz lower than the TX signal and the I/Q offset was calibrated before every measurement. 65.2MHz: -99dBm 145.2MHz: -102dBm 435.2MHz: -104dBm 945.2MHz: -85dBm 1300.2MHz: -89dBm 1500.2MHz: -89dBm 1800.2MHz: -84dBm Also please note that we have a hole at 1200 MHz - there are no valid PLL settings here. The RX is not a sensitivity-wonder. Perhaps a preamp? Best regards, Christian - -- - --------------------------------------------------- | maintech # Dipl.
