ffset values, set with the Antenna Gain softkey that are larger or smaller than 0 dB will activate the
enhancement label TDF at the right diagram border.
Measurements
In this section, every measurement type is introduced by a short description.
Output Power measurement
The Output Power measurement (Output Power softkey) determines the maximum and average output
power during a burst of the equipment under test (EUT). For this purpose a complete packet is recorded
in the zero span.
Fig. 4-12 Output power measurement
The peak value is determined from the complete contents of the measurement curve, whereas the
average power is calculated from an area of at least 20% to 80% of the burst.
During the Output Power measurement the Bluetooth demodulator is active in order to determine the
sync word within the signal, which is later–on used as the trigger basis. The Bluetooth demodulator is
placed in a signal path without video filter. This is why the video filter cannot be activated with the
Output Power measurement.
The EUT (equipment under test) must keep the following limits according to the RF Test Specification:
• P
AV
< 100 mW (20 dBm) EIRP
• P
PK
< 200 mW (23 dBm) EIRP
• If the EUT is conforming to power class 1: P
AV
> 1 mW (0 dBm)
• If the EUT is conforming to power class 2: 0.25 mW (–6 dBm) < P
AV
< 2.5 mW ( 4 dBm)
• If the EUT is conforming to power class 3: P
AV
< 1 mW (0 dBm)
A violation of these limits is marked on the screen in red color.
