6.4.3 Bandgap Calibration
[Main menu, Radio Operations, Calibration, Bandgap Calibration]
The BANDGAP REFERENCE SET VALUE is a digital variable to a DA
converter, which should be set to give a BANDGAP_VOLTAGE of 2.5 V. The
bandgap voltage is not temperature-dependent.
Figure 18 Bandgap Calibration menu.
Alt. 1 INCREMENT
Increases the bandgap by 1 step to 129.
Alt. 2 DECREMENT
Decreases the bandgap by 1 step to 127.
