Input Level (RF Zone display)
Input Lvl displays the average power in the P25 channel under test.
Note: When the RF input power on the RF In/Out port is above +20 dBm (100 mW), the R8100 utilizes a
broadband power detector for the measurement. The “Input Lvl” field in the RF Zone changes to “Watt
Meter” to indicate this measurement mode. For best accuracy disable the Pre-amplifier in Monitor Mode,
and set the Gen Port in Generate Mode to RF In/Out.
Freq Error (RF Zone display)
Freq Error displays the frequency difference of the received P25 transmission carrier minus the R8100
Monitor Frequency.
