Nice, thanks. Carrier Freq makes the motor windings sing (resonate) and sometimes that's really annoying for the neighbors.

[@stephensickle]

Thanks , but was hoping for more on the difference on the analyzer due to changing the values/khz as the carrier freq affects the performance of the drive

How many of the Fluke MDA-550 features carry over to the Fluke 438 MKII?

[@fridayswithbrandon]

Not many. The 438-ii is designed to look at just the incoming power where as the NDA is focused on measurements in and after the VFD.
