I am using Schaffner’s Profline Series to perform the above mention immunity
test. The NSG 2200-1 (AC Switch) does not provide a low voltage signal where I
can connect to the oscilloscope to monitor the percentage dip or voltage
variations. 

 

Please advise me on the following:

(1)     A suitable circuit which I can easily build to step down the voltage
such that I can connect directly to the scope (safely). 

(2)     Or any other alternatives?

 

I have an Agilent infiniium digital scope with a 10:1 miniature passive probe
300V max.

 

Thanks.
