:CRECovery:JSANalysis:PLLoop:OJTF:BANDwidth
Command Syntax
:CRECovery{1:8}:JSANalysis:PLLoop:OJTF:BANDwidth} <count>
<count> is a double.
Where the {1:8} specifier identifies a slot number. The slot number is associated with the N1060A, N1076A/B, N1077A, N1078A, or 86108B module with Option JSA. When an 86108B module is used, the slot number is always 1.
Query Syntax
:CRECovery{1:8}:JSANalysis:PLLoop:OJTF:BANDwidth?
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. The maximum bandwidth setting is 20 MHz. Use the :CRECovery:JSANalysis:PLLoop:JTF:BANDwidth command to set the bandwidth of the Jitter Transfer Function (JTF).
| 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 |
