JITKIT Source Setup
Use the JITKIT Source Setup dialog to set up the jitter source signal(s). The JitSource1 and JitSource2
traces are replicas of your channel, but they also have the ability to be easily and automatically time
synchronized with the Jitter Track (JitTrack). They also provide the convenience of using two inputs of a
differential signal to the oscilloscope and having one trace without needing to separately set up a math
function to perform this activity.
You can define shared source settings that apply to all measurement parameters or you can define
individual source settings for each measurement. If you choose to define individual source settings, you
define the source settings for each separate measurement parameter that you select in the Measure
dialog.
JITKIT Source Setup dialog
1. Under Global Source Settings Control, select a mode:
l
Use Shared Settings - applies the definitions and settings on this dialog to all measurement
parameters.
l
Use Individual Settings - lets you configure individual settings for each measurement. If you
choose to configure individual settings you define the source settings for each separate meas-
urement parameter in the Measure dialog.
2. For each source, touch the check box next to the Trace On field to turn the trace on.
3. In the JitSource1 (Clock) Definition and Settings section, if you are using a differential probe, touch
the 1 Input (or Diff. Probe) button. Now, touch inside the Input1 field below the 1 Input (or Diff.
Probe) button and select an input source from the Select Source pop-up window.
OR
If you are using two single-ended probes to calculate the differential signal, touch the Input1-Input2
button. Input2 is subtracted from Input1. Touch inside each Input field and select an input source for
each from the Select Source pop-up window.
Note: If you do use two single-ended input channels on the oscilloscope to acquire a differential
signal, be sure to correctly deskew the two inputs prior to using them as an input to JitSource.
