Harmonic extraction and Display

Hello,

We are developing a product which compensates up to 50th harmonic in some load. So, we are in need of a Harmonic Extraction and Display meter which can display up to 50th harmonic present in the load. The sampling frequency need to be 25KHz (only then we will be able to construct the 50th harmonic properly). Does Analog Devices have any device which suits my requirements closely.

Regards, Vishnu
