Performed is one single measurement. The signal "Marker 1" indicates the active
part of the first frame block. The measured result confirms the expected level of
-30 dBm ("Frame Block#1 > Boost = 0 dB").
4. Select "Gate Source > Marker 2", select "Change", and trigger the measurement
with "Start".
Performed is one single measurement. The signal "Marker 2" indicates the active
part of the second frame block. The measured result confirms the expected level of
-35 dBm ("Frame Block#2 > Boost = -5 dB").
To perform baseband power measurements on bursted signals using the multi-
gated acquisition
The baseband power measurements using multi-gated acquisition use marker signals,
"Marker 2" and "Marker 3", to determine the measurement period and the particular
part of the signal to be analyzed. Perform the following settings to generate a bursted
WLAN 802.11n signal consisting of three frame blocks with short active part and differ-
ent long idle periods between them.
This example is based on the predefined marker signals. The goal is to capture and
measure the short active frame parts to explain the measurement in principle. In your
particular case, you would rather measure some exact signal parts or even frame parts
and you may have to define one or more customized marker signals.
1. Press the PRESET key.
2. In the block diagram, select "Baseband A > IEEE 802.11" and perform the settings
shown on the following figure:
