AD698 operation

Hi all,


I am using the AD698 and getting familiar with its operation.

I have set the excitation up at 10kHz 15Vrms and then use a voltage divider to drop the level to about 2Vrms before it feeds into the B channel.


When I check the BFILT1 pin with an oscilliscope I only see -12.6V dc.


I expected to see the 2VRMS signal rectified.


Can anybody explain what I should see and why I would be getting the -12.6 vdc?


kind regards
