Measure Commands

:MEASure:CLOCk:METHod:ALIGn

Command
:MEASure:CLOCk commands are available when clock recovery is used by licensed
N O T E
software (like the E2688A High Speed Serial software or the N5400A/N5401A EZJIT Plus
jitter analysis software).
:MEASure:CLOCK:METHod:ALIGn {CENTer | EDGE}
When using an explicit method of clock recovery, the
:MEASure:CLOCk:METHod:ALIGn command specifies how the clock is
aligned with data:
• CENTer — Clock edges are aligned with the center of data.
• EDGE — Clock edges are aligned with data edges. In this case, Time
Example When using an explicit method of clock recovery, this example specifies
that clock edges are aligned with the center of data.
myScope.WriteString ":MEASURE:CLOCK:METHOD:ALIGn CENTer"
Query

:MEASure:CLOCK:METHod:ALIGn?

The :MEASure:CLOCk:METHod:ALIGn? query returns the clock recovery
method's edge alignment setting.
Returned Format
[:MEASure:CLOCk:METHod:ALIGn] {CENT | EDGE}
Example
This example places the current edge alignment setting of the clock
recovery method in the variable strSetting, then prints the contents of the
variable to the computer's screen.
myScope.WriteString ":SYSTem:HEADer OFF"
myScope.WriteString ":MEASURE:CLOCK:METHOD:ALIGn?"
strSetting = myScope.ReadString
Debug.Print strSetting

Interval Error (TIE) is measured directly from the data edge to the
clock edge.
