Interconnecting the PXIe-5842 VST

Complete this procedure to interconnect the modules of the PXIe-5842 VST.

Before beginning this procedure, install the relevant modules for your instrument in your PXI Express chassis and refer to the interconnection guidelines.

The PXIe-5842 VST comprises the following modules:

  • PXIe-5842
  • PXIe-5655

Once you complete this procedure, your instrument should appear as follows:

  1. PXIe-5842 (module)
  2. PXIe-5655
  3. Semi-rigid 2.92 mm (m)-to-2.92 mm (m) cables

Complete the following steps to interconnect the PXIe-5842 VST:

  1. Connect the local oscillator for RF output.
    Cable Torque PXIe-5842 Connector PXIe-5655 Connector
    Minimum Maximum
    Semi-rigid 2.92 mm (m)-to-2.92 mm (m), 136104A-01 0.9 N · m (8 lb · in.) 1.0 N · m (8.85 lb · in.) RF OUT: LO IN LO 0 OUT
  2. Connect the internal reference clock.
    Note Install this cable such that the flatter bend is closest to the PXIe-5842REF: IN connector and the more angled bend is closest to the PXIe-5655REF OUT connector. The correct orientation leaves less space between this cable and the cable you have already installed.
    Cable Torque PXIe-5842 Connector PXIe-5655 Connector
    Minimum Maximum
    Semi-rigid 2.92 mm (m)-to-2.92 mm (m), 136103A-01 0.9 N · m (8 lb · in.) 1.0 N · m (8.85 lb · in.) REF: IN REF OUT
  3. Connect the local oscillator for RF input.
    Cable Torque PXIe-5842 Connector PXIe-5655 Connector
    Minimum Maximum
    Semi-rigid 2.92 mm (m)-to-2.92 mm (m), 136106A-01 0.9 N · m (8 lb · in.) 1.0 N · m (8.85 lb · in.) RF IN: LO IN LO 1 OUT

You have now provided the reference clock and LO sources for the PXIe-5842 VST. Physical setup for the PXIe-5842 VST is now complete.
