The :MEASure:CLOCk:METHod command sets the clock recovery method
to:
• FOPLL (first order phase- locked loop).
• SOPLL (second order phase- locked loop).
• EQFOPLL (equalized first order phase- locked loop).
• EQSOPLL (equalized second order phase- locked loop).
• PCIE (PCI Express).
• FC (Fibre Channel).
• EXPFOPLL (Explicit First Order PLL).
• EXPSOPLL (Explicit Second Order PLL).
• EXPlicit (Explicit Clock).
• FIXed (Constant Frequency).
• FLEXR (FlexRay Receiver).
• FLEXT (FlexRay Transmitter).

Some of these command options have been deprecated — options for specifying clock
recovery PLL options have been moved to the new commands
":MEASure:CLOCk:METHod:JTF" on page 502 and ":MEASure:CLOCk:METHod:OJTF" on
page 504. See also ":MEASure:CLOCk:METHod" on page 496.

:MEASure:CLOCk commands are available when clock recovery is used by licensed
software (like the E2688A High Speed Serial software or the N5400A/N5401A EZJIT Plus
jitter analysis software).
