In the Auxiliary I/O Menu, click the
10MHz Ref Signal
softkey button, and select
PXIe 100MHz
.
Step 6: (Optional) Turn On Sync Mode
Optionally, to lessen the jitter between channels in different modules so that it is
more like the jitter between channels within a single module, you can turn on Sync
mode. Sync mode uses the trigger system in the master module for all modules.
When Sync mode is off, this is called Asynchronous mode. Asynchronous mode
uses the trigger systems in all modules where the trigger output from the master
module is fed to the trigger input of the slave modules.
To turn on and set up Sync mode:
1
For each M924xA oscilloscope module in the multi-module system (that is, the
master module and the slave modules), click the
Sync
softkey button to enable
Sync mode.
When you turn on Sync mode for the first time (after InfiniiVision software
start-up), there is a red unlocked image shown in the top right of the screen.
For example:
•
On the master module, you see:
•
On the slave modules, you see:
This red unlocked image indicates that the clock phase for the Sync mode
trigger is not aligned.
2
Open a Command Prompt window on the chassis controller.

To align the reference clock signals, you must run the KtScopeCal.exe
application using the "-a" or "-p" option:
•
If setting up Sync mode triggers on a new or modified system, use the
KtScopeCal -a
command. For example:
