Inverter Power board into a 100w load, a standard CRO probe on one side (yellow) and a differential probe on the other (pink).   there is some common mode interference on the CRO probe, a few clip on toriods reduced it a bit, still not ideal but I was mainly interested in the looking at the dead time for any glitches etc.                                           Measured between the Gate and Source at R26 -T4 and R28 - T2 (-48V) I did not have a probe setup to measure across the resistors, very tight space there when the Cap boards are on and the inverter is running into a load.
