      My Anritsu MG3633A generator provided a 1.42 GHz sine wave at -50 dBm, which was fed by a cable with 2,2 dB loss into tha A port of my RSP2pro. The sdruno software measured a signal level of -48.6 dBm instead of the expected -52.2 dBm. My brandnew RSPdx in the same setup, however, missed the exact level by only very few tenth of a dB. Is the level error typical of the older RSP devices? Is there a possibility to trim the RSP2pro? Grateful for any experiences, DL5KAZ
