Re: Antuino to calculate db loss

iz oos
 

Hi Raj, yesterday when I tried to join the Antuino group I got the answer that my email was already added. But apparently I am not receiving the emails.

The version I have was built in late August and It showed values if I remember right (I have not it here right now) - 19 or - 21db depending on frequency. It is clear to me how to plot and see the readings on different frequencies but I cannot see how to measure the insertion losses eg. Maybe I have just to study the whole messages I missed on the Antuino group!

Ooz,
Join us on the antuino group..

Set your center freq, select SNA mode.
Connect filter input to the top (antuino OUT) connecter and filter out to bottom (antuino IN) connector.
click Plot.

The plotted graph has a cursor at the center, you can move the cursor with the knob
and take readings at different spots.

I mean the loss in db within the passband of the filter. Or a loss in a cable.

Hello Folks, finally Antuino knocked to my door! I have played with it plotting bandpass and notch filters. Nice and practical, however how do I determine the loss of my filters in terms of db using Antuino? Can you provide a simple example so I can get the trick?
