Default Re: Measuring power in a known load with a 'scope.

I got fed up of hunting around for power resistors, meter, leads etc, so built this a few weeks ago. The meter can switch to either channel, and can be set to 20 or 60V fsd (mean reading, rms cal). The BNC's carry attenuated voltages for scope monitoring. A switch selects precision 4, 8 or 15 ohms @ around 100W per channel.
