D About BPSK and QPSK modes
BPSK and QPSK modes are available for PSK.
• BPSK (Binary Phase Shift Keying) mode is the most
commonly used mode.
• QPSK (Quadrature Phase Shift Keying) mode has
error correction capability to provide better decoding
than BPSK mode in marginal condition. However,
more accurate tuning is required with QPSK mode,
due to the tight phase margin of QPSK.
q During PSK mode selection, push [DECODE] (F-3)
to display the PSK decode screen.
w Push [<MENU1>] (F-1) to select PSK decode sec-
ond menu.
e Push [B/QPSK] (F-2) to toggle between BPSK and
QPSK mode alternately.
