How to make PXI-6733 use PXI_Clk10 as the Reference Clock?

[JSHAN]

I'm using PXI-6733 and it is put in the PXIe-1065 Chassis. As you know, the PXIe-1065 has a clock PXI_Clk10 and distributes it to all its slots. Now I want to use the PXI_Clk10 as the reference clock for PXI-6733, meaning I want to lock the PXI-6733 onboard clock to the Chassis clock PXI_Clk10.

The question is that I can't select the PXI_Clk10 as a Ref.Clock. It is not in the list.And I have filter the channel names. Have you ever encounter this problem? Can PXI-6733 use PXI_Clk10?

10MHz is routed via RTSI line. Unfortunately, 6733 doesn't have one.
