Command Syntax
:CHANnelN:SCRecovery:PLLoop:OJTF:BANDwidth <bandwidth>
<bandwidth> is a double.
Where N identifies a specific channel and must be selected from {1:8}{A|B|C|D}. For example, CHANnel3C.
Query Syntax
:CHANnelN:SCRecovery:PLLoop:OJTF:BANDwidth?
Description
For the selected channel's software clock recovery, 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 :CHANnel: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 |
Before this command can take effect, you must disable shared acquisition parameters with the :CHANnel:RTSCope:TRACkcommand.
Requires FlexDCA revision A.06.70 and above.
