For the latter\, you would have to feed the USRP a known \n(calibrated) noise source that is well above the USRP noise floor such as an\nHP 346 noise source. Then read the value from the spectrum and just\n re-scale the samples to your known PSD. If you change the FFT bin size\,\n decimation\, tuning\, etc\, you may need to re-scale.\n\nI suppose you coul d also feed the USRP with a CW tone of known power to\nfigure out it's gain \, then terminate the input with 50 ohms (i.e. -174\ndBm/Hz) and measure th e power (which would be -174 dB/Hz + NF + gain).\n\nIn either case\, you ne ed a known power source to convert the dB to dBm\, and\nnoise to fill your bandwidth to get the 1/Hz.\n\nLou\nKD4HSO\n\n\nact...
