Test Conditions
The following setup and environmental conditions are required to ensure the NI PXIe-4610
meets published specifications.
•
Keep connections to the NI PXIe-4610 as short as possible. Long cables and wires act as
antennas, picking up extra noise that can affect measurements.
•
Verify that all connections to the NI PXIe-4610 are secure.
•
Use 50
Ω
BNC coaxial cables for all connections to the NI PXIe-4610 inputs.
•
Maintain an ambient temperature of 23 °C ± 5 °C. The NI PXIe-4610 temperature will be
greater than the ambient temperature.
•
Keep relative humidity below 90%.
•
Allow a warm-up time of at least 15 minutes to ensure that the NI PXIe-4610 measurement
circuitry is at a stable operating temperature.
•
Allow adequate warm-up time for all of the instruments and equipment according to the
manufacturer instructions.
•
Ensure that the PXI/PXI Express chassis fan speed is set to High, that the fan filters are
clean, and that the empty slots contain filler panels. For more information, refer to the
Maintain Forced-Air Cooling Note to Users
document available at ni.com/manuals.
Initial Setup
Refer to the
NI PXIe-4610 Getting Started Guide
for information about how to install the
software and hardware and how to configure the device in Measurement & Automation Explorer
(MAX).
Note
When a device is configured with MAX, it is assigned a device identifier.
Each function call uses this identifier to determine which DAQ device to verify or,
verify and adjust.
Verification
The following performance verification procedures describe the sequence of operations and
provide test points required to verify the NI PXIe-4610. The verification procedures assume that
adequate traceable uncertainties are available for the calibration references.
