(1) All measurement results are obtained using the EM430F6137RF900 with BOM according to tested frequency range (see Table 48).
(2) The resolution (in Hz) is equal for all frequency bands.
(3) Depends on crystal used. Required accuracy (including temperature and aging) depends on frequency band and channel bandwidth and
spacing.
(4) Time from leaving the IDLE state until arriving in the RX, FSTXON, or TX state, when not performing calibration.
(5) Settling time for the 1-IF frequency step from RX to TX
(6) Settling time for the 1-IF frequency step from TX to RX
(7) Calibration can be initiated manually or automatically before entering or after leaving RX or TX.
