■
Position RF cables with instrument connectors to ensure center pins are
straight and aligned before mating.
■
For all threaded RF connectors for your PXIe-5842 instrument, engage and
finger-tighten the connector nuts. The connector nuts should thread easily
without binding, but if not, ensure the connector is straight and that center
pins have not been damaged.
■
Carefully tighten all threaded RF connectors to the torque specified in
the interconnection process for your instrument using an appropriate torque
wrench or torque screwdriver and driver bit; tighten only until the wrench
reaches the torque limit.
Notice
Incorrect torque at threaded connections can damage
device connectors and degrade signal integrity.
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.
All PXIe-5842 instrument configurations include a PXIe-5655 module physically
adjacent to the PXIe-5842 module. These two modules are interconnected in the
same way for all PXIe-5842 instrument configurations.
Complete the following steps to interconnect the PXIe-5842 VST:
1. Connect the local oscillator for RF output.
