:JSAMemory:PLLoop:JTF:BWIDth?
Deprecated command. For FlexDCA revision A.06.70 and above, use the :JSAMemory:PLLoop:JTF:BANDwidth?
command.
Query Syntax
:JSAMemory:PLLoop:JTF:BWIDth?
Query Response
Returns <bandwidth> which is a double.
Description
From the JSA memory database, returns the clock recovery emulation's bandwidth for the Jitter Transfer Function (JTF) for a first- or second-order PLL. The following table shows the bandwidth settings for some standards. The maximum bandwidth setting is 20 MHz. Use the :JSAMemory:PLLoop:OJTF:BWIDth
query to return the bandwidth for an Observed Jitter Transfer Function (OJTF).
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 | — | 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 |
JSA requires an 86108A/B module with Option JSA. To use JSA in Jitter Mode, 86100D Option 200 Enhanced Jitter Analysis or N1010A Option 200 Enhanced Jitter Analysis is required.
Requires FlexDCA revision A.02.50 and above.
