An oscilloscope can be used as a RF Voltmeter when using a fixture with
capacitive divider.
Added to section "Injection Transformer, With Capacitive Divider,
Fixture" is a photo using an oscilloscope. Image is at resonance with
Generator set for Oscilloscope 1Vrms. Measuring 0.708Vrms frequencies,
3dB BW, results with expected Q.
