Potential Problems During Boot Process
AIF 140 Variable Attenuator Algorithm
Ref power at atten 12 dB
(Option B1X)
A25 Wide band A-IF
DIF 40 Variable Attenuator Algorithm
Ref power at atten 21 dB
A3 Digital IF
Narrow Band Step Cal Ad justment Alignment
Algorithm
Alignment signal
originates on A3
D-IF, then goes
through A16
Reference through
the input
attenuators,
through A13 Front
End, through A2
Analog IF, and back
to A3 Digital IF. If
Option B1X present,
A25 WB A-IF
switches calibrator
signal to A16
Reference.
Narrow Band Step Cal Alignment Algorithm A16 Reference
A9/A10 Attenuators
DIF 40 Step Cal Adjustment Alignment
Algorithm
Since this is wide
band alignment
done for 40 MHz
BW signal path, A2
Analog IF is not
included in the
signal path.
