Setting the RF Gain (AGC off mode only)
The picture below shows how to adjust the RF gain, in order to optimize the transmission performance in terms of
CNR, CSO, CTB and BER.
Figure 43 — Setting the RF Gain on the OTOT-EM55X
OTOT-EM55X application software release 2.0 and later supports this feature.
Notes:
• The RF gain setting is only relevant in AGC-on mode.
• The setting range for RF gain might change slightly from device to device due to production tolerances.
• Changing the RF gain changes the input sensitivity of the OTOT-EM55X in AGC off mode; 0dB is the nominal
RF gain. Setting the RF gain to e.g. 2dB improves the input sensitivity of the OTOT-EM55X from 80dBµV to
78dBµV.
