Characteristic
Description
RF Channel Power
Measures the average RF power in a user-de
fi
ned channel. The default value of channel bandwidth
is taken from the selected standard. The acceptable values for channel numbers are taken from the
selected standard. The user can input the channel center frequency instead of the channel number.
Units and Resolution
Watts (W), dBm
3 signi
fi
cant digits for W; 0.1 dB for dBm units
Accuracy
± 0.75 dB: –20 dBm to +30 dBm, ± 0.5 dB typical
± 1.25 dB: –80 dBm to –20 dBm, ± 1.0 dB typical
Reference information: Accuracy is guaranteed for input signals between –80 and +30 dBm total
power (CW or peak envelope). Accuracy speci
fi
cation is typical down to –120 dBm total power.
RF Power (GSM/EDGE)
Measures the average RF power of the useful part of a GSM or EDGE burst (GMSK or 8-PSK
modulation), as determined by the location of the burst Training Sequence.
Units and Resolution
dBm: 0.01 dB for dBm units
Accuracy
For GSM or EDGE (GMSK or 8-PSK modulation) burst signals, the RF power measurement
accuracy is:
± 1.0 dB: –20 dBm to +30 dBm, ± 0.75 dB typical
± 1.5 dB: –80 dBm to -20 dBm, ± 1.25 dB typical
Reference information: Burst timing is determined from the location of the burst Training Sequence.
If Burst timing cannot be found, the power measurement will be done on an arbitrarily selected
segment of the signal equal to the useful part of a slot.
