:MEASure:CLOCk:METHod
Command
:MEASure:CLOCk:METHod {FOPLL,<data_rate>,<loop_bandwidth>}
| {EQFOPLL,<data_rate>,<loop_bandwidth>}
| {SOPLL,<data_rate>,<loop_bandwidth>, <damping_factor>}
| {EQSOPLL,<data_rate>,<loop_bandwidth>, <damping_factor>}
| {PCIE,{DEEMphasis | TRANsition | BOTH}}
| {FC,{FC1063 | FC2125 | FC425}}
| {EXPFOPLL,<source>,{RISing | FALLing | BOTH},
<multiplier>,<clock_freq>,<loop_bandwidth>}
| {EXPSOPLL,<source>,{RISing | FALLing | BOTH},
<multiplier>,<clock_freq>,<loop_bandwidth>,<damping_fact>}
| {EXPlicit,<source>,{RISing | FALLing | BOTH}[,<multiplier>]}
| {FIXed,{AUTO | {SEMI[,<data_rate>]} | <data_rate>}}
| {FLEXR,<baud_rate>}
| {FLEXT,<baud_rate>}
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).
The EQUalized clock recovery methods are only available if the
oscilloscope has the High Speed Serial option and the Serial Data
Equalization option installed and the features are enabled.
<source> {CHANnel<N> | FUNCtion<N> | WMEMory<N>}
<N> CHANnel<N> is an integer, 1 - 4.
NOTE
: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).
