#99702 - A resistor Responding to: ???'s previous message |
can be specified as to its exact "composition" In fact over this trivial 3 1/2 decade range the resistance will dominate if any care is taken with the design. Power then will be I squared R across the bandwidth of interest. Since the L and C components present are mostly a function of layout there contribution if excessive can easily be calibrated out. With attention to lay out the total error should not even approach the margins.
RMS converters in general are intended for sinusoidal or near sinusoidal input. The relevant specification is the “form factor" IIRC that specification is much more frequency dependant than the basic accuracy specification All that is needed is a top end DSO with the built in math package( incredible accuracy beautiful display wallet shattering cost) Hey two out of three ain’t bad :) Terry |
