Test Equipment

The following table lists the test equipment required for calibrating NI 5402/5406 modules.

InstrumentRecommended ModelRequirements
DMMNI 4070,
Agilent 34401A
If these instruments are unavailable, use a DMM with a DC accuracy of ≤±50 ppm and resolution ≤1 μV.
Frequency CounterAgilent 53131A with timebase option 010 If this instrument is unavailable, use a frequency counter with the ability to measure 10 MHz or higher sine waves and a frequency accuracy of ±500 ppb.
Power MeterAgilent E4419B with Agilent E9304A power sensorIf these instruments are unavailable, use a power meter with a power accuracy of ±0.10 dB that can measure flatness from 50 kHz to 50 MHz.
Chassis PXI-1042,
PXI-1042Q
Use with PXI modules.
BNC to SMB CableUse a 50 Ω male BNC to female SMB cable.
BNC to Banana Plug AdapterUse a female BNC to male banana plug adapter.

Test Conditions

The following setup and environmental conditions are required to ensure the NI 5402/5406 meets published specifications.

  • Keep connections to the NI 5402/5406 short. Long cables and wires act as antennas, picking up extra noise that can affect measurements.
  • Keep relative humidity between 10 and 90% non-condensing.
  • Maintain a temperature between 18 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.
  • Plug the PXI chassis or PC and the calibrator into the same power strip to avoid ground loops.
  • (PXI) Ensure that the PXI chassis fan speed is set to HIGH, that the fan filters are clean, and that the empty slots contain filler panels.

Device Setup

The device must be configured in Measurement & Automation Explorer (MAX) to communicate with NI-FGEN.

  1. Install the NI-FGEN driver software.
  2. Power off the computer or chassis that will hold the device and install the device in an available slot.
  3. Power on the computer or chassis and launch MAX.
  4. Configure the device identifier and select Self-Test to ensure that the device is working properly.
  5. Launch the Calibration Executive procedure and complete the setup wizard.
Note Notes  When a device is configured with MAX, it is assigned a device identifier. This device identifier is used to open an NI-FGEN session.

           For more information about configuring and testing your device in MAX, refer to the NI Signal Generators Getting Started Guide.

           If the NI 5402/5406 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 = Test Frequency ± [Test Frequency * Frequency Accuracy(ppm)]

DC Gain and Offset

TestLimits = TestValue ± ( 0.5% of Offset + 2 mV + 0.5% of Amplitude )

Square Wave Gain and Offset

TestLimits = TestValue ± ( 0.5% of Offset + 2 mV + 0.5% of Amplitude )

Sine Wave Flatness

TestLimits = TestValue ± ( TestValue * 0.4dB )

Specification for passband flatness is +/- 0.4 dB relative to 50 kHz
