Re: AD8307 probe-How is it used?
Reference that new question.
To elaborate.
It doesn’t matter if I use a three port 6 dB hybrid (transformer type) combiner, or a resistive three port (ie 3 x 17 ohm) star combiner, results are the same except the resistive type output is not – 6.0 dBm, but is about – 4.0 dBm or so, (due to the resistive type).
It also doesn’t matter to either combiner type if I turn off the sig gens by their internal Carrier ON/OFF, or by removal of cable.
And it doesn’t matter if I terminate the input port that has had its sig gen cable removed from, results are still the same.
All this is realisable in the home workshop with two sig gens, a combiner and AD8307 type Meter.
Who said they were not useful?
Pondering? ...
