Testing Profile A
✓
Profile A is key to D3.1 modem communication via an OFDM carrier.
This is where command and control, range, and registration occurs.
✓
In practice, profile A may be assigned lower mixed modulations, like
QAM 64/16, so every D3.1 modem can communicate. Lower modulation
profiles can operate at lower MER/CNR and power levels.
✓
If profile A isn’t locked or has uncorrectable CWE, a modem may roll
back and use only SC QAMs in 3.0 mode.
THINGS TO CHECK:
Lock status:
locked
Uncorrectable CWE
:
none
Profile A
is boot profile; ALL 3.1 modems
must be able to use profile A
