CDR:SOFTware<m>:ALGorithm
<Algorithm>
Sets the software algorithm that is used for clock data recovery.
Suffix:
<m>
.
1..2
Number of the software CDR setup
Parameters:
<Algorithm>
CFRequency | PLL | FF | PLLStart
CFRequency
Constant frequency. CDR uses the nominal bit rate to generate
the clock signal. The method assumes that the frequency of the
signal is constant during the complete acquisition.
PLL
Phase-locked loop control system. It can follow slow deviations
in the frequency of the data stream.
FF
Feed forward algorithm, a mathematical optimization method.
Feed forward is available if none of the listed serial standards is
used ("Custom"). It is faster than PLL, i.e., the settling time is
shorter. Feed forward is also more precise than PLL. To set up
the algorithm, set the bandwidth and the relative bandwith.
*RST:
PLLStart
Usage:
Asynchronous command
CDR:SOFTware<m>:SERStandard
<SerialStandard>
Sets the serial standard. The nominal bit rate and bandwidth settings are set according
to the selected standard, no estimation is required. The serial standards are available
only if the instrument is able to support its maximum nominal bit rate.
