External clock RSPDuo and RSP2
The output from GPSD0 (and presumably the mini version?) can be directly applied to the RSPDuo and can feed to another RSP2 for example. Ordinarily the RSP2 needs an attenuator for this input. Is the attenautor on the RSP reference clock input still required?The reference clock circuitry has been significantly enhanced and can now interface to a GPSDO
delivering a 0-3v output without any interface circuit. It is capable of operating as a clock
master to other RSPduos or RSP2s and will also operate as a clock slave when using a RSP2 as a
clock master. In tests, we find that we can ‘hot swap’ between an internal and external clock
without hanging the MSi2500, which is not possible on the RSP2.
What output setting is used on the GPSDO?
