"Integration" Fits a rectangle pulse of the same energy into the pulse signal as a
reference and thus determines the pulse top power.
This algorithm is recommended for:
●
Pulse signals with modulation
●
If the pulse energy is considered
For example, if you compare the measurement result to a mea-
surement result of a thermal power sensor.
"Peak" Assigns the pulse peak power to the pulse top power.

High Reference Level ← Configuration tab
Defines the end of the rising edge and the start of the falling edge of the pulse. Used
for the measurement of the rise or fall time.

Low Reference Level ← Configuration tab
Defines the start of the rising edge and the end of the falling edge of the pulse. Used

7.5 Time Gate
In combination with the R&S NRX, all power sensors that support the timeslot mea-
surement, can use also this measurement type. The power sensor measures the aver-
age power in time intervals chosen by you. These time intervals are called time gates.
You can configure up to 4
different gates, but use only one at a time for measuring.
The time resolution is determined by the sampling rate of the power sensor. An exter-
nal trigger signal or internal signal triggering is required for synchronization.
