BUS<m>:CDR:PLL:ORDer <PLLOrder>
Sets the order of the PLL: first or second order. PLL of higher order can compensate
for more complex jitter behavior.
Suffix:
<m>
.
1..4
Parameters:
<PLLOrder> FIRSt | SECond
*RST: SECond
BUS<m>:CDR:PLL:RELBwidth
<PLLRelBw>
Sets the relative bandwidth, that is the ratio of the nominal bit rate to the PLL band-
width.
Suffix:
<m>
.
1..4
Parameters:
<PLLRelBw> Range: 10 to 5000
Increment: 1
*RST: 1667
BUS<m>:CDR:RESults <Results>
The PLL requires some time to synchronize to the phase of the data stream. You can
select when the CDR algorithm returns clock edges.
Suffix:
<m>
.
1..4
Parameters:
<Results> ALL | AISYnc
*RST: ALL
BUS<m>:CDR:SYNC <InitialSync>
Defines the phase reference for the first clock edge.
Suffix:
<m>
.
1..4
Parameters:
<InitialSync> SAMPle | DATaedge
SAMPle
The first clock edge matches the first sample of the waveform at
the left border of the display.
DATaedge
The first clock edge matches the first edge of the data signal.
