8 | ni.com | NI PXIe-5694 Calibration ProcedureTest ConditionsThe following setup and environmental conditions are required to ensure the NI 5694 meetspublished specifications.• Keep cabling as short as possible. Long cables and wires act as antennas, picking up extranoise that can affect measurements.• Verify that all connections, 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 and NI-RFSAis loaded and recognizes the NI 5694. The warm-up time ensures that the NI 5694 and testinstrumentation are at stable operating temperature.• In each verification procedure, insert a delay between configuring all devices and acquiringthe measurement. This delay may need to be adjusted depending on the instruments usedbut should always be at least 1,000 ms for the first iteration, 1,000 ms when the power levelchanges, and 100 ms for each other iteration.• Plug the PXI Express chassis and the calibrator into the same power strip to avoid groundloops.• Use a torque wrench appropriate for the type of RF connector that you are using.NI recommends a 0.565 N · m (5 lb · in.) wrench for SMA connectors and a 0.90 N · m(8 lb · in.) wrench for 3.5 mm connectors.• Ensure that the PXI Express chassis fan speed is set to HIGH, that the fan filters, if present,are clean, and that the empty slots contain filler panels. For more information, refer to theMaintain Forced-Air Cooling Note to Users document, available at ni.com/manuals.Initial SetupRefer to the NI 5694 Getting Started Guide for information about how to install the NI-RFSAsoftware, the NI 5694 hardware, and how to configure the NI 5694 in Measurement &Automation Explorer (MAX).As-Found and As-Left LimitsThe as-found limits are the published specifications for the NI 5694. NI uses these limits todetermine whether the NI 5694 meets the device specifications when it is received forcalibration.The as-left limits are equal to the published NI specifications for the NI 5694, less guard bandsfor measurement uncertainty, temperature drift, and drift over time. NI uses these limits toreduce the probability that the instrument is no longer calibrated at the end of the calibrationcycle. |
