> White emitter follower circuit attached.
Here are the results. First, the circuit draws 33.3 mA at 12 vols. And
it's gain is 1:1 as expected with emitter follower - checked that with
RF generator as an input just to make sure that I built it correct.
With HP10544A the output level is below +8 dBm:
(with 2 meters of RG174 and SMA-connectors between the circuit and SA)
Now the harmonics look like this:
And 2nd harmonic level:
So the spec told that 2nd harmonic should be more than 25 dB down, it is
just in spec...
So the final result looks that the 10544A is OK but it really has this
kind of output spectrum?
