PHASE DET RAMPS
. This diagnostic monitors voltage ramps used in the phase
detector. If these voltage ramps are outside the nominal range, Warning appears,
which means that the instrument should be serviced.
NOTE. The following diagnostics (ADC BUS, GENLOCK INPUT, LTC
POS INPUT, and LTC NEG INPUT) are available only in modules with the
BLACK 1 / REF IN connector.
ADC BUS. This diagnostic displays the condition of the Genlock input circuit:
Stuck – A 12
-bit display showing the bits stuck high (H), low (L), or OK (-).
Short – A 12-bit display showing any shorted adjacent lines (SS) (-).
NOTE. Fo
r all bits to move, the correct signal must be applied.
GENLOCK INPUT. This diagnostic displays the following:
Min – The minimum value from the genlock ADC for the present input signal.
Max – The maximum value from the genlock ADC for the present input signal.
LTC POS INPUT. This diagnostic displays the following:
Min (Raw) – The minimum raw ADC values of the positive LTC input.
Max (Raw) – The maximum raw ADC values of the positive LTC input.
LTC NEG INPUT. This diagnostic displays the following:
Min (Raw) – The minimum raw ADC values of the negative LTC input.
Max (Raw) – The maximum raw ADC values of the negative LTC input.
