CDR:HARDware:PLL:BWIDth
<PLLBandwidth>
Sets the PLL bandwidth. It defines the part of the spectrum that the PLL can follow dur-
ing synchronization. The PLL bandwidth is usually defined by the transmission stan-
dard.
Parameters:
<PLLBandwidth>
Range:
Nominal BITRate * Range of RELBwidth (depend-
ent range)
Increment: 10
*RST:
599.88E+3
Default unit: Hz
Usage:
Asynchronous command
CDR:HARDware:PLL:RELBwidth
<PLLRelBw>
Sets the relative bandwidth, that is the ratio of the nominal bit rate to the PLL band-
width.
Parameters:
<PLLRelBw>
Range:
500 to 3000
Increment: 1
*RST:
1667
Usage:
Asynchronous command
CDR:HARDware:PLL:DAMPing
<DampingFactor>
Sets the damping factor, which is only relevant for second order PLL.
Parameters:
<DampingFactor>
Range:
0.5 to 1
Increment: 0.01
*RST:
0.7
Usage:
Asynchronous command
CDR:HARDware:SAMTime
<UntIntvlOffs>
Sets a sampling time for the clock signal, an offset for the clock edge in relation to the
bit start. The clock edge sets the beginning of the unit interval. The sampling time is a
number between 0 and 1. Value 0 sets the clock edge to the beginning of the bit
period; value 0.5 sets the clock edge to the middle of the bit period.
Parameters:
<UntIntvlOffs>
Range:
0 to 1
Increment: 0.01
*RST:
0.5
Default unit: UI
Usage:
Asynchronous command
Jitter analysis and clock data recovery
