The AMP400 is our high frequency Hysteresisgraph system which will be used to test the magnetic properties of soft magnetic materiel at frequencies in the approximate range of 100 Hz - 20M Hz.  The target upper end of 20MHz is ambitious and not currently available by any competing system on the market at this time.

Power Amplifier: Proprietary design based on multiple STV9556 parts(or similar video amp) in             parallel(see Doug Self 5532 parallel amp design)
Shunt:1 ohm 20 watts
Signal Generator:  AD9834 DC coupled with differential signaling for low noise operation
Acquisition: Multiple AD6649 parts with staggered clocks, interleaving controlled by FPGA
Frequency Range: 100 Hz - 20 M Hz
