Power Mode
Defines which method is used to calculate the signal power at the first instrument out-
put. The signal power at the other outputs is calculated according to the current power
relations of all channels and signals.
The different power modes are illustrated for the two signals, shown on Figure 6-1.
Figure 6-1: Example: time plans of 2 signals with different allocated subframes and channel band-
width per allocation
left = Every second subframe is allocated; for all subframes, channel bandwidth BW = 100 MHz
right = 2 allocated subframes, channel bandwidth of the first allocation BW
1
= 100 MHz and of the second -
BW
2
= 50 MHz
