The following table lists the test equipment required for calibrating PXI-5422/5442 modules.
|Digital Multimeter (DMM)||PXI-4070,
|DC gain and offset||DC Accuracy: ≤ ±50 ppm
Resolution: ≤1 μV
|Spectrum Analyzer or Frequency Meter||Agilent HP 53131A or HP 53132A with timebase option 001, 010, or 012||Frequency accuracy||Ability to measure 10 MHz or higher sine waves
Frequency accuracy of ±500 ppb
|Chassis||PXI-1042, PXI-1042Q||All||Use with PXI modules|
|PXIe-1062Q||All||Use with PXI Express modules|
|Male BNC-to-Female SMB Cable||—||DC gain and offset, frequency accuracy||50 Ω, RG-233|
|Male Banana-to-Female BNC Adapter||—||DC gain and offset||—|
The following setup and environmental conditions are required to ensure the PXI-5422/5442 meets published specifications.
|Note If the NI 54xx module fails after calibration, return it to NI for repair or replacement.|
The following test limits are derived from the published specifications.
TestLimits = TestFrequency ± [TestFrequency * FrequencyAccuracy (25 ppm)]
Main Analog Path Gain
TestLimits = TestValue ± ( 0.2% of Amplitude + 500 μV )
Main Analog Path Offset
TestLimits = TestValue ± ( 0.05% of Offset + 500 μV + 0.2% of Amplitude )
Direct Path Gain
TestLimits = TestValue ± ( 0.2% of Amplitude )
Direct Path Offset (Verification Only)
TestLimits = TestValue ± (TestValue * 0.03 V)
