oven-controlled crystal oscillator (OCXO). You can also lock the NI 5600 to an external frequency
reference clock signal and drive this reference to the backplane. To use an external frequency
reference, you must connect this signal to the FREQ REF IN connector on the NI 5600 module front
panel.
Installing the NI 5620 IF Digitizer Module
To install the NI 5620 module, complete steps 2 through 11 in the
Installing PXI Modules
NI PXI modules are sensitive instruments that should be handled carefully. Do not expose the module
to temperatures or humidity beyond the rated maximums.
Note
For information about the rated maximums, refer to your device specifications document,
located at

.
Keep the module free of dust by cleaning only with compressed air. Do
not
clean the device with any
solvents or liquids.
To prevent damage to the device caused by ESD or contamination, handle the device using the edges or
the metal bracket. For more information about the radio-frequency interference characteristics of your
hardware, refer to the
Read Me First: Safety and Electromagnetic Compatibility
document.
Caution
You
must
power off and unplug the chassis before installing the device.
You can install PXI modules in any PXI slot marked with a peripheral slot compatibility
glyph (a circle containing the slot number).
You also can install PXI modules in any PXI hybrid slot marked with a peripheral slot
compatibility glyph (the letter “H” and a solid circle containing the slot number).
Install a PXI module by completing the following steps:
1.
Power off and unplug your PXI chassis.
2.
If the chassis has multiple fan speed settings, ensure that the fans are at the highest setting. Do not
set the fan speed to low or turn the fan off.
3.
Position the chassis so that you allow ample space between the chassis fan intake and exhaust vents.
Blockage by walls or obstructions affects the air flow needed for cooling. Refer to the chassis
documentation for more information about cooling.
4.
Make sure the ejector handle is in the unlatched (downward) position.
5.
Remove the rubber screw covers from the captive screws in the module front panel.
6.
Holding the module by the ejector handle, slide it into an available PXI (or hybrid) slot, as shown
in Figure 2. Ensure that the base card (the card on the left when looking at the front of the module)
engages with card guides in the chassis.
7.
Slide the module completely into the chassis and latch by pulling up on the ejector handle.
8.
Tighten the screws in the module front panel. Performance may suffer if the screws are not
tightened properly.
9.
Verify that the PXI chassis fans are operable and free of dust and other contaminants that may
restrict airflow.
