[Elecraft] XG3 Calibration from 10MHz Standard?

[brian]

Hi Maverick,

The accuracy of the DG1022A stinks with the internal oscillator. Counter 
likewise is inaccurate. Look at the specs -- something like 50 ppm.

I had one and measured how bad it really was.  In all other respects, it 
was a decent product.  Apparently waveform synthesis is cheap and easy 
but including a decent reference oscillator isn't at the Rigol's price 
point.

When I tried to lock it to a Rb source and it was much better but still 
off (low) a small amount.  To make it accurate, I had to use as 
super-stable reference oscillator at slightly greater than 10 MHz 
(10,000,000.175Hz) to get the RIGOL to be accurate.
