on page 85.
2.8 Measuring average burst power (Burst Av mode)
An R&S NRP-Z1x, R&S NRP-Z2x(x), or R&S NRP-Z8x sensor is required for this mea-
surement.
To perform a burst-average power-measurement, you need a pulsed RF signal. If you
use an R&S NRP-Z1x or R&S NRP-Z2x(x) sensor, the pulse repetition frequency of the
signal should not exceed 10 kHz.
Setting the burst mode.
1.
Connect the power sensor to connector A on the R&S NRP2 and apply a pulsed
signal with a level between –10 dBm and +10 dBm.
2. Press the (PRE)SET hardkey twice.
A measurement window is now available.
3. Change to the "Sensor" menu and select "Mode".
The "Mode" dialog box opens.
4. Select "Trace & Statistics".
5. In the trace mode check that the sensor detects a signal and reliably triggers.
For information concerning reliable triggering see chapter 2.7, "Graphically repre-
senting power versus time", on page 42.
6. Change back to the "Sensor" menu and select "Burst Av" in the "Mode" dialog box.

The burst mode parameters are displayed at the bottom of the dialog box.
To exclude the pulse build-up and decay phases from the measurement, you can set
the "Excluded from Start" and "...from End" parameters accordingly.
