Description
Defines the bandwidth of a first- or second-order PLL's Observed Jitter Transfer Function (OJTF). The following table shows the bandwidth settings for some standards. Use the :TIMebase:SCRecovery:PLLoop:OJTF:DFACtor command to set the Damping Factor.
| Standard | First-Order Loop Filter | Second-Order Loop Filter |
|---|---|---|
| SAS 1.5 Gb/s | 900.0 kHz | 900.0 kHz |
| SAS-SSC 1.5 Gb/s | — | 1.300 MHz |
| SATA 1.5 Gb/s | — | 2.100 MHz |
| SAS 3.0 Gb/s | 1.800 MHz | 1.800 MHz |
| SAS-SSC 3.0 Gb/s | — | 1.838 MHz |
| SATA 3.0 Gb/s | — | 1.000 MHz |
| SAS 6.0 Gb/s | 3.600 MHz | 3.600 MHz |
| SAS-SSC 6.0 Gb/s | — | 2.600 MHz |
| SATA 6.0 Gb/s | — | 4.200 MHz |
| QPI | — | 3.000 MHz |
| USB 3.0 | — | 4.900 MHz |
This acquisition setting is automatically shared with all UXR oscilloscope input channel waveforms. To independently configure for specific channels, use the :CHANnel:RTSCope:TRACk command.
Requires FlexDCA revision A.06.70 and above.
