Description
OD[0-3] Phase Shift
Increment Unit
The incremental step, always 45 degrees, by which
the OD output signal will be shifted relative to the
VCO output signal. This is a fixed value, displayed
for user convenience.
Static Adjustment
Y
When selected, a single, unchanging phase
adjustment must be chosen for this OD. When this
is enabled, the ”Phase Adjustment Multiplier” field
will also be enabled.
Phase Adjustment Multiplier
Y
This value is multiplied by the ”OD[0-3] Phase
Shift Increment Unit” to determine the total
”OD[0-3] Static Phase Adjustment”.
OD[0-3] Static Phase
Adjustment
The calculated total phase shift, in degrees,
performed by this OD.
Dynamic Signal-Driven
Incremental Adjustment
Y
When selected, this enables dynamic phase
adjustment mode, where the phase of the OD
output signal will advance by ”OD[0-3] Phase Shift
Increment Unit” degrees each time a rising edge is
applied to the associated phase inc input signal.
When this mode is enabled, the ”Phase
Adjustment Multiplier” field will be disabled.
