I imagine that this level of studly low-impedance drive is required to allow the ADCs to sample at high rates the current to charge and discharge the sampling capacitors at megasample rates isn't small. For a particular kVA, there is a band of % impedance for economical designs, with minimum cost at one level. Adjustable level. I is a dc-dc converter employing ZCS. The impedance converter can be used to convert 50 ohm to 75 ohm or 75 ohm to 50 ohm for RF measurements.
