2. Mute behavior when:
Mute on LORS is enabled
Mute on Clock Not Synchro is enabled
LORS TimeOut is not reached
If the LORS TimeOut is not reached when the clock reference comes back, another
timeout starts (fixed to 60 sec), after which the module will mute if the Clock Synchro
is still not OK:

2.9 Power Measurements
EXACT-V2 provides the capability to measure the forwarded and reflected RF power
output from the transmitter, as described in the following figure.
Using an RF coupler, the user will connect the output of the transmitter to both FWP_In
and RFP_In dedicated inputs.
Each input is able to receive:
- An RF signal from 0 to -20dBm (±0.5dBm accuracy from 0 to -10dBm, ±1dBm
accuracy from 0 to -10dBm)
