Measure Commands 25
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 643
:MEASure:RJDJ:SCOPe:RJ
Command
:MEASure:RJDJ:SCOPe:RJ {ON, <RJrms> | AUTO | OFF}
The :MEASure:RJDJ:SCOPe:RJ command can specify the removal of the
oscilloscope's calibrated random jitter from the reported RJ.
• ON — Enables the "manual" removal of a known oscilloscope random
jitter from the reported RJ.
• <RJrms> — The known oscilloscope random jitter to remove from the
reported RJ.
• AUTO — This option cannot be selected until the scope jitter calibration
has been run (use the Calibrate scope jitter button in the front panel user
interface). When selected, the calculated oscilloscope random jitter is
removed from the reported RJ.
The calculated oscilloscope random jitter is shown in the jitter
measurement results (see page 629) as "Scope RJ(rms)".
• OFF — Disables the removal of the oscilloscope's calibrated random
jitter from the reported RJ.
Example This example specifies 300 fs of known oscilloscope random jitter.
myScope.WriteString ":MEASure:RJDJ:SCOPe:RJ ON, 300e-15"
Query :MEASure:RJDJ:SCOPe:RJ?
The :MEASure:RJDJ:SCOPe:RJ? query returns the oscilloscope RJ settings.
Returned Format
[:MEASure:RJDJ:SCOPe:RJ] {ON, <RJrms> | OFF}<NL>
Example This example places the oscilloscope RJ settings in the strScopeRJSettings
variable and displays it on the computer's screen.
myScope.WriteString ":SYSTem:HEADer OFF" ' Response headers off.
myScope.WriteString ":MEASure:RJDJ:SCOPe:RJ?"
strScopeRJSettings = myScope.ReadString
Debug.Print strScopeRJSettings
NOTE
This command is available when the EZJIT+ software is installed.
