Hello,

I am calibrating my test setup and I have a question about the distance beteween antenna and target.
I would like to have 1 meter between my hyperlog 7060 antenna and my DUT and test it at 868 MHz (for esample).
My question is where should I take the reference point for the 1m distance? on the tip of the antenna? on the SMA connector?
on the middle of the antenna?

Regards, Ramon.

Hello,

Thanks for your kind reply.

Then I will take the nose/tip/front of the antenna as my reference point.

10 times? my lab is not so big !! I thought 3 times lambda was enough, is it not?

Regards, Ramon.

You can try but to be 100% on the safe side use 10 times.
