TDS 694 waveforms problems


Gennady
 

Hello group.

I am building half-bridge inverter and trying to check waveforms wit my Tek.

It looks perfectly fine while checking signal on gates of the FETs
please see album "Tek waveforms" - picture TEK00011

And when I am trying to see signal across the resistive load I have next - TEK0012 - it is heavily distorted and with wrong voltage.
For reference I am adding picture from my old trustful analog scope - Lider.

Your insight will be very appreciated.
Gene.
