The next AREU meeting is scheduled for June 01 at the Bell Shoals Baptist Church.?
I brought some equipment for show and tell last meeting but forgot some key parts to?make the demonstration work.?
I will be better prepared this time (maybe).?
The demos I have planned will demonstrate the accuracy of various frequency?standards and how to measure their accuracy.?
I will bring a GPS standard but I don't have any idea if it will work indoors.?
I will also bring a?Rhibidium?frequency standard that is very close in accuracy?to the GPS standard but does not require an antenna to operate.?
I will also bring an oven controlled standard that is extremely accurate but not as good?as the GPS or?Rhibidium?standards.?
Frequency error will be measured two ways.?
One will use a dual trace oscilloscope and the other will use a doubly balanced mixer?with a simple analog meter for indication.?

I will also bring a scalar network analyzer?to measure the characteristics of a directional?coupler.
Please come if you can.?
Tony

Wish I could be there.
