Test Conditions
Review and become familiar with the entire procedure before beginning the calibration
process.
The following setup and environmental conditions are required to ensure the PXIe-1092
chassis meets published specifications.
•
Keep cabling as short as possible. Long cables and wires act as antennae, picking up extra
noise 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 below 80%.
•
Ensure that the PXIe-1092 chassis has been continuously powered for at least 24 hours
prior to calibration to allow the 10 MHz oscillator frequency to stabilize.
•
Ensure that the Frequency Reference has been continuously powered as specified by its
manual for its accuracy to meet the minimum requirements specified in Table 1.
