:CRECovery:JSANalysis:PLLoop:JTF:BWIDth
Deprecated command. For FlexDCA revision A.06.70 and above, use the :CRECovery:JSANalysis:PLLoop:JTF:BANDwidth command.
Command Syntax
:CRECoveryN:JSANalysis:PLLoop:JTF:BWIDth <bandwidth>
<bandwidth> is a double.
Where N identifies the slot number and must be selected from {1:8}. 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
:CRECoveryN:JSANalysis:PLLoop:JTF:BWIDth?
Description
Defines the bandwidth of a first- or second-order PLL's Jitter Transfer Function (JTF). The following table shows the bandwidth settings for some standards. The maximum bandwidth setting is 20 MHz. Use the :CRECovery:JSANalysis:PLLoop:OJTF:BWIDth command to set the bandwidth of the Observed Jitter Transfer Function (OJTF).

|---|---|---|
| SAS 1.5 Gb/s | 900.0 kHz | 900.0 kHz |
| SAS-SSC 1.5 Gb/s | — | 2.328 MHz |
| SATA 1.5 Gb/s | — | 4.097 MHz |
| SAS 3.0 Gb/s | 1.800 MHz | 1.800 MHz |
| SAS-SSC 3.0 Gb/s | — | 3.291 MHz |
| SATA 3.0 Gb/s | — | 1.791 MHz |
| SAS 6.0 Gb/s | 3.600 MHz | 3.600 MHz |
| SAS-SSC 6.0 Gb/s | — | 4.655 MHz |
| SATA 6.0 Gb/s | — | 8.194 MHz |
| QPI | — | 5.692 MHz |
| USB 3.0 | — | 10.03 MHz |
Requires an N1060A, N1076A, N1077A, or 86108A/B clock-recovery module that has Option JSA (Jitter Spectrum Analysis and SW Clock Recovery Emulation).
