Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 1157
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.
FUNCtion<N> and WMEMory<N> are:
An integer, 1- 4, representing the selected function or waveform memory.
<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.
<baud_rate> A real number used for the baud rate.
Example This example sets the clock recovery method to phase- locked loop.

Query :MEASure:CLOCk:METHod?
The :MEASure:CLOCk:METHod? query returns the state of the clock
recovery method.

Example This example places the current setting of the clock recovery method in
the variable strSetting, then prints the contents of the variable to the
computer's screen.
