300 MZ post fltr det
300 MHz post-lter detector error
Cause: The internal 300 MHz reference signal is not at the correct power level after the lter
stage. This error will only occur on power up of the system, or when the TEST command is
invoked,
either
from
the
front
panel
or
remotely
.
Cure:
Return
to
