Hi Guys
Does anyone know what the bias voltage should be for the gate of this transistor/pallet board? I know the current is meant to be 200mA MAX but need to work out the voltage
Any help greatly appreciated!
Bias voltage for SD2942 48V 350W pallet

It is different for every transistor. You set them to get the current right.
That is why you have trimmer on each board.

It is of course the current.
Now how do you measure current? With current meter of course, make sure drive is disabled.
Start with zero voltage and slowly increase while observing current.

There is nothing to disable, just do not apply any RF drive when you do this.
Next connect amp meter in series with power supply and measure away.

You have to disconnect drain of the tested fet and connect it separately to power supply via amp meter.
How exactly you can disconnect drain depends on the pallet, most give an option to do that via jumpers or have drains separated anyway.
