The :MEASure:CLOCk:METHod command sets the clock recovery method to
FOPLL (first order phase-locked loop), SOPLL (second order phase-locked
loop, EXPFOPLL (Explicit First Order PLL), EXSOPLL (Explicit Second Order
PLL), EXPlicit (Explicit Clock), or FIXed (Constant Frequency).
<source>
{CHANnel<N> | FUNCtion<N> | WMEMory<N>}
<N> is an integer, 1 - 4.
<data_rate>
A real number for the base data rate in Hertz.
<damping_
factor>
A real number for the damping factor of the PLL in bits per second.
<loop_
bandwidth>
A real number for the cutoff frequency for the PLL to track.
<multiplier>
An integer used as the multiplication factor.
<clock_freq>
A real number used for the clock frequency of the PLL.
<track_freq>
A real number used for the tracking frequency of the PLL.
<damping_fact>
A real number used for the damping factor of the PLL.
This command is only available when the E2688A High Speed Serial Software.
