Description This softkey displays the latched status of the following fault
messages.
PEAK FAIL
TRACK FAIL
RAMP FAIL
SPAN FAIL
ADC FAIL
NONE
Indicates that the peak algorithm is unable to align
the YTM passband to the frequency of the YO.
This fault indication is possible only if a peaking or
autotrack routine has been initiated.
Indicates that the autotrack algorithm is unable to
calculate the calibration constants needed to track
the YTM passband to the frequency of the YO.
This fault indication is possible only if an autotrack
routine has been initiated.
Indicates that the ramp algorithm is unable to adjust
the sweep ramp voltage to lO.OOV at the end of
the sweep. Initiate a full self-test to gather more
information if this fault is indicated.
Indicates that the span algorithm is unable to adjust
the YO to achieve the correct frequency at the end
of a band. This fault indication is possible only if a
sweep span routine has been initiated.
Indicates that the internal YO V/GHz line adjusted
at power-on or at preset is unable to calibrate.
Initiate a full self-test to gather more information if
this fault is indicated.
Indicates that the ADC (analog-to-digital converter)
is not responding to a measurement request within
the time-out period. The ADC is used extensively
in the operations of the synthesizer. Initiate a full
self-test to gather more information if this fault is
indicated.
