Use

Identical to complex scope, except has magnitude block before scope sink (which is now of the float type).

In the following example, a Mode S transmission can be seen. Mode S uses Pulse Position Modulation (PPM), for which the first demodulation step is treating it as an AM signal (i.e. take magnitude of complex stream and ignore phase).
