Either the root-mean-square power or the peak power is measured, depending on
whether the RMS detector or the PEAK detector is selected. The function always
uses TRACE 1 of the selected screen.
The following parameters are to be set for this measurement:
•
•
•
•
•
•
•
•
During the measurement, each pulse is mapped into a pixel of the screen, i.e. any
change of the trace can be detected only at the left-hand edge of the screen. Maxi-
mum measurement speed is as usual achieved with the display switched off.
In the example below, a GSM pulse sequence of 8 pulses is measured with 5 µs
trigger offset, 434 µs measurement time/pulse, video trigger with 50% trigger thresh-
old, and peak detection:
