6. Define a trigger offset of -50
μ
s .
7. Select the "Time Domain Power" measurement function from the "Select Measure-
ment" dialog box.
8. In the Time Domain Power configuration dialog box, set all four results to "On".
9. Set the "Limit State" to "On".
10. Define the left limit at 326
μ
s and the right limit at 538
μ
s .
This range corresponds to the useful part of the GSM burst.
The mean power of the useful part of the GSM burst is calculated to be -13 dBm.

7.10.1 About the Measurement
With this measurement it is possible to measure the harmonics easily, for example
from a VCO. In addition, the total harmonic distortion (THD) is calculated.
For measurements in the frequency domain, the Harmonic Distortion measurement
starts with an automatic search for the first harmonic (= peak) within the set frequency
