Test Conditions
The following setup and environmental conditions are required to ensure the PXIe-5654 meets
published specifications.
•
Keep cabling as short as possible. Long cables act as antennas, picking up extra noise that
can affect measurements.
•
Verify that all connections to the PXIe-5654, including front panel connections and
screws, are secure.
•
Maintain an ambient temperature of 23 °C ± 5 °C.
•
Keep relative humidity between 10% and 90%, noncondensing.
•
Allow a warm-up time of at least 30 minutes after the chassis is powered on. The warm-
up time ensures that the PXIe-5654 is at a stable operating temperature.
•
In each verification procedure, insert a delay between configuring all instruments and
acquiring the measurement. This delay may need to be adjusted depending on the
instruments used but should always be at least 1,000 ms for the first iteration, 1,000 ms
when the power level changes, and 100 ms for each other iteration.
