Boxing Time

Well,

You may remember the 35MHz to 4.4GHz signal generator made from cheap eBay components I was fiddling with last time.

I've stuck it in a box now:



I've removed L1 from the board:



so that there is no power to the on-board 25MHz XO. I'm running mine using the shack 10MHz frequency standard I made back here. This external oscillator input simply connects to the SMA socket on the back of the board.

I've recently made a distribution amplifier for the frequency reference so  I have 8 50R outputs at 10MHz to lock a recently acquired Microwave frequency counter and also my HPO signal generator.

Good egh?
