© National Instruments Corporation 5 NI PXI-5600 Calibration Procedure
Test Conditions
Follow these guidelines to optimize the connections and the environment
during calibration:
• Keep connections to the NI PXI-5600 short. Long cables and wires act
as antennae, picking up noise that can affect measurements.
•Use 50 Ω coaxial cable for all connections to the NI PXI-5600.
• Keep relative humidity between 10 and 90%, noncondensing,
or consult the hardware documentation for the optimum relative
humidity.
