PXIE-4144 Four Channel Source-Measure Unit (SMU)
The following setup and environmental conditions are required to ensure the NI 4144 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 device, including front panel connections and screws, are secure.
• Ensure that the PXI chassis fan speed is set to HIGH, that the fan filters (if present) are clean, and that the empty slots contain slot blockers and filler panels. For more information about cooling, refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/manuals.
• Allow a warm-up time of at least 30 minutes after the chassis is powered on and NIDCPower is loaded and recognizes the NI 4144. The warm-up time ensures that the NI 4144 and test instrumentation are at a stable operating temperature.
• Use shielded copper wire for all cable connections to the device. Use twisted-pair wire to eliminate noise and thermal offsets.
• To ensure the system has had adequate time to settle, wait one second after requesting a new current or voltage or after changing a load before taking a measurement.
• Keep relative humidity between 10% and 70%, noncondensing
