Test Equipment

The following table lists the test equipment required for calibrating PXI-5422/5442 modules.

Instrument Recommended Model Specification Requirements
Digital Multimeter (DMM) PXI-4070,

Agilent 34401A,

Keithley 2000

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

Test Conditions

The following setup and environmental conditions are required to ensure the PXI-5422/5442 meets published specifications.

  • Keep connections to the device as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements.
  • Keep relative humidity below 80%.
  • Maintain a temperature between 18 °C and 28 °C.
  • Allow a warm-up time of at least 15 minutes to ensure that the measurement circuitry of the device is at a stable operating temperature.
  • (PXI/PXI Express) Ensure that the PXI/PXI Express chassis fan speed is set to HIGH, that the fan filters are clean, and that the empty slots contain filler panels. For more information, refer to the Maintain Forced-Air Cooling Note to Users documents available at ni.com/manuals.

Device Setup

  1. Install the PXI-5422/5442 in the PXI chassis or the PC according to the instructions in the NI Signal Generators Getting Started Guide.
  2. Configure the hardware using Measurement & Automation Explorer (MAX).
  3. Launch the Calibration Executive procedure and complete the setup wizard.
Note Note  If the NI 54xx module fails after calibration, return it to NI for repair or replacement.

Test Limit Equations

The following test limits are derived from the published specifications.



Oscillator Frequency

TestLimits = TestFrequency ± [TestFrequency * FrequencyAccuracy (25 ppm)]

DC Gain and Offset

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)
