AD8310 offset problem

Hi every body!!


I'm trying to use the AD8310 logarithmic amplifier to detect very low RF signals.


Here are some screenshot from the results I'm getting out of my setup.


The first screenshot (profile1) shows a normal response to a sinewave burst.

The second one (profile) shows the response to a square wave burst.


As you can see I've got a weird tail at my second screenshot.


The same problem can be seen if I add an offset to my sinewave.


Does anyone has an explanation to that behaviour?
