Do I need mosfets in my Signal generator

I'm thinking about putting some dual MOSFET finals in my 6060b?

In response to the overwhelming number of videos showing crazy forward power coming from radios that barely develope enough power to get out of there own way I thought it would be fun for some of the newbies to see what affect audio has on wattmeter readings. So below I hooked my 6060 up to a small average reading meter that I modified to be sensitive enough to display the output of the generator essentially full scale is less than 1 watt. The real teaching moment here is to show that 99% of the time what you seeing in these videos is nothing more than rectified audio and NOT RF!. As you can see over 60% of the forward power is the result of the audio component, Again NOT RF.

It certainly proves a watt meter is an ignorant device that doesn't know the difference between one kind of power or another. Is there any way you can include an oscilloscope with the test? The reason I ask is because I'm curious how much the waveform from the signal generator differs from an AM transmitter. Is there a modulated carrier or just a sine wave?
