[Amps] how to bias a Tek 575 for a MRF150

[Dan Sawyer]

All,

I would like to use a Tek 575 to test several MRF-150 devices. The issue 
seem to be the gate bias and gate step are coupled. That is the bias 
range increases with the bias step value. The result is when measuring 
lower step values the bias range is insufficient to turn the device on. 
At higher step values the device is overdriven.

Does anyone have a suggestion?
