Fourier modulator test.app
Feeds a small amount of the transmitter signal back to the receiver and tests if a pulse is
being amplified. You can see the difference to the modulator signal by the rise time at the
beginning. The signal intensity should be similar, but due to the variations of compo-
nents cannot really be used to accurately measure the power.
The measurement is repeated 20 times and should give stable intensity results. This can
be done both for 1H and for the C13 channel. Select the right channel by changing the
"observe nucleus" under "instrument settings"
i
Note: some oscillations on the top of the signal are normal and are caused by alias
effects.
