    I purchased a GPSDO (Leobodnar MINI Precision) and connected it to my RSP2 Pro. The GPSDO is set to 24 MHz at 16ma and all seems to be working well. If I tune the RSP2 to 24 MHz and set the mode for SAM and DSB the frequency offset indicates +.5 Hertz.

    With an antenna connected this value varies either side of zero, but with the Hi Z port terminated with a 1000 ohm resistor the value is steady at +.5 Hertz. My question is this:

    Should I use the built in frequency calibration feature to further calibrate the software to the reference 24 MHz frequency? Or should I ignore the +.5 Hertz offset shown while using the external GPSDO reference input?
