I've been in the market for a GPSDO to use as an external clock and calibration tool for some RF test equipment. Last night I placed an order for a Leo Bodnar LBE-1420, partly based on some posts on this forum that seemed to give it high praises.
I looked at their "Precision GPS Reference Clock", but for $100 more, I couldn't really see any advantage, at least not based on the website descriptions. They're both 1x10-12 accuracy, both use TCXO's, both have 3.3v output for active antennas, both produce a 50 ohm, 3.3v CMOS level square wave output. But the 1420 has a larger frequency range and lower phase noise. No reference of the Allan Deviation for the 1420.
Other than adjustable output amplitude and ability to be powered by USB or a 5-12v adapter, what is the benefit of the "Precision GPS Reference Clock" over the LBE-1420?
