If you are using the VCSEL I-V Test Subsystem One Channel Expansion
Kit to add a channel to an existing subsystem,
you must install a new PXIe-4135 SMU into the PXI chassis. After you
install the SMU in the chassis, you must finish the remaining steps of the subsystem set up
process to completely assemble the new subsystem channel.
Before you begin this procedure, ensure
that the PXIe-1092
chassis is powered off and connected to
facility ground through the AC power cable or grounding terminal.
To prevent damage to the PXIe-4135 caused by ESD or contamination, handle the
module using the edges or the metal bracket.
Complete the following steps
to install a PXIe-4135 into the PXI chassis.
Select the PXI chassis slot for the new PXIe-4135.
NI recommends installing the new PXIe-4135 in a chassis slot next to the PXIe-4135 SMUs already installed in the chassis.
This hardware arrangement ensures adequate temperature and noise control for
subsystem hardware components.
Refer to the Channel Configurations section to view an example
of the recommended hardware arrangement within a PXI chassis.
Unscrew the PXI filler panel from the PXI chassis using the #2 Phillips
Remove the PXI slot blocker from the PXI chassis slot.
Remove the black plastic covers from all the captive screws on the PXIe-4135 front panel.
Touch any part of the chassis to discharge static electricity.
Ensure that the ejector handle is in the downward (unlatched) position.
Place the PXIe-4135 edges into the guides at the top and bottom
of the chassis. Slide the PXIe-4135 into the slot until it is fully
Latch the module in place by pulling up on the ejector handle.
Secure the PXIe-4135 front panel to the chassis using the
front-panel mounting screws and the #2 Phillips screwdriver.
Tightening the top and bottom
mounting screws increases mechanical stability and also electrically
connects the front panel to the chassis, which can improve the signal
quality and electromagnetic performance.
