Alignment Verification
– Go to
Product ––> Initialize ––> Normal mode . This is needed to give
a SW reset for the phone. Which in turn is needed to get the aligned
I/Q values in use.
– Go to
RF controls menu and start transmission on channel 60, power
level 10, TX data type 1.
– Check the levels of CHF and CHF + 67.71 kHz. Both the levels
should be at least 30 dB down to the wanted sideband CHF - 67.71
kHz. If both or either of the specifications is not met adjust the required
values (I and Q DC offsets for CHF and amplitude and phase for CHF
+ 67.71kHz) to meet the specifications.
