SDRPLAY DX ordered and on the way. Is there a PDF instructions sheet for using the external clock port?
The level should not substantially exceed 3v p-p. Larger levels should not cause damage, but they may result in degraded phase noise.
This application note for connecting to a Leo Bodnar Precision GPS Disciplined Oscillator shows the setup: http://www.sdr-kits.net/documents/SDRPlay%20RSP%20External%20Clock%20in%20Cable%20use.pdf The RSPdx is more plug and play than the earlier RSP2 and RSP2pro versions so less care is needed in adjusting the exact levels in the case of problems.
