11.6.14.7 Evaluating the Results
The commands required to control the demodulation of signals at the marker position
are described in Chapter 11.8.8.14, "Marker Demodulation", on page 886.
11.6.14.8 Programming Example: EMI Measurement
This example demonstrates how to detect electromagnetic interferences (EMI) in a
remote environment.
