:MEASure:CLOCk:METHod:JTF
{FOPLL,<data_rate>,<jtf_loop_bandwidth>}
| {EQFOPLL,<data_rate>,<jtf_loop_bandwidth>}
| {SOPLL,<data_rate>,<jtf_loop_bandwidth>, <peaking>}
| {EQSOPLL,<data_rate>,<jtf_loop_bandwidth>, <peaking>}
| {EXPFOPLL,<source>,{RISing | FALLing | BOTH},
<multiplier>,<clock_freq>,<jtf_loop_bandwidth>}
| {EXPSOPLL,<source>,{RISing | FALLing | BOTH},
<multiplier>,<clock_freq>,<jtf_loop_bandwidth>,<peaking>}
The :MEASure:CLOCk:METHod:JTF command specifies the clock recovery
PLL's response in terms of the Jitter Transfer Function's (JTF) 3 dB
bandwidth.
You can set these types of PLL clock recovery methods:
• FOPLL (First Order PLL).
• SOPLL (Second Order PLL).
• EQFOPLL (Equalized First Order PLL).
• EQSOPLL (Equalized Second Order PLL).
• EXPFOPLL (Explicit First Order PLL).
• EXPSOPLL (Explicit Second Order PLL).
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.
For setting phase- locked loop (PLL) clock recovery methods in terms of
the Observed Jitter Transfer Function (OJTF), see
":MEASure:CLOCk:METHod:OJTF" on page 515.
For setting other clock recovery methods, see ":MEASure:CLOCk:METHod"
on page 507.
<source> {CHANnel<N> | FUNCtion<F> | WMEMory<N>}
<N> CHANnel<N> is an integer, 1- 4.
WMEMory<N> is an integer, 1- 4.
<F> FUNCtion<F> is an integer, 1- 16.
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).
