[time-nuts] GPSDO 10MHZ Splitter

[Paul Bicknell]

Hi you can always use a resistive splitter 

So if you have an output impedance of 50 ohm 

You use 2 off  50 resistors  to feed 2 off 50 ohm loads  / signals to other
equipment with a 50 ohm input

So we have  a load comprising of 2 off 100 ohm loads in parallel = 50 ohm 

This method is often used to supply several devices and 4 way splitters are 
Often used in the RF industry remembering the voltage / power reduction for
each splitter 

I personally will be using a 4 way splitter on my LEO Bodnar for the 
10 mhz reference noting that the LEO Bodnar has a selectable current for its
output 

Coax T connectors should be avoided when using square wave signals

Subject: [time-nuts] GPSDO 10MHZ Splitter

Is there an easy, and cheap way to add a splitter the 10Mhz signal 
from GPSDO, without going to a distribution amplifier to
feed two different devices?

I really don't want to build a complicated project, or 
spend $200.00 dollars for an 8 output distribution amp
off the net.  One output would be dedicated for my
 counter time base, and the other would be an 'extra' 
10MHZ source for another counter, or just to display on the scope.

I don't have a GPSDO yet, I just can't decide on one.
I am leaning to the Trimble, but it's still undecided.

Could anyone comment on buying a "Refurbished by Seller"
GPSDO on E-bay. They are a few dollars cheaper, but I really
want one I can have trust and confidence in.

Sorry for the long post.
Thanks, Don
