Subcarrier spacing 312.5 kHz default
user settable
Maximum subcarrier spacing is
approximately the
analysis BW/57, thus 438 kHz
for Option B25 (25 MHz BW),
and 700 kHz for Option B40
(40 MHz BW).
Lock range
±2 × sub-carrier spacing,
±625 kHz default
Frequency accuracy
±8 Hz + tfa a
a. tfa = transmitter frequency
× frequency reference accuracy.
