PXIe-5673 Calibration Procedure
Test Conditions
The following setup and environmental conditions are required to ensure the PXIe-5673 meets
published specifications.
•
Verify that the PXIe-5611, PXIe-5450, and PXI-5650/5651/5652 are properly connected as
indicated in the
NI RF Signal Generators Getting Started Guide
before starting verification.
•
Keep cabling as short as possible. Long cables and wires act as antennas, picking up extra
noise that can affect measurements.
•
Verify that all connections, including front panel connections and screws, are secure.
•
Use a torque wrench appropriate for the type of RF connector you are using.
NI recommends using a 0.565 N · m (5 lb · in.) torque wrench for SMA connectors and a
0.90 N · m (8 lb · in.) torque wrench for 3.5 mm connectors.
