Test Conditions

The following setup and environmental conditions are required to ensure the PXI-5900 meets published specifications.

  • Keep cables as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements.
  • Keep relative humidity between 10 and 90% non-condensing, or consult the hardware documentation for the optimum relative humidity.
  • Maintain a temperature of 23 ±5 °C.
  • Allow a warm-up time of at least 10 minutes after the NI-SCOPE driver is loaded. Unless manually disabled, the NI-SCOPE driver automatically loads with the operating system and enables the device. The warm-up time ensures that the measurement circuitry of the PXI-5900 is at a stable operating temperature.
  • Verify that all connections, including front panel connections, are secure.
  • 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

  1. Install the PXI-5900 in the PXI chassis according to the instructions in the NI High-Speed Digitizers Getting Started Guide.
  2. Configure the hardware using Measurement & Automation Explorer (MAX).
  3. Launch the Calibration Executive procedure. Calibration Executive guides you through the required connections.

Test Limit Equations

The following test limits are derived from the published specifications.

Vertical Offset and Vertical Gain

TestLimits = TestValue ± (0.2% of Input + 500 µV)

Bandwidth and Flatness

1, 2, 3, 4, 5 MHz Frequencies

TestLimits = ±1dB

for reference power measurement verification: TestLimits = 39.1 µW ± 4 µW

6 MHz Frequency

TestLimits = ± 3dB

for reference power measurement verification: TestLimits = 39.1 µW ± 4 µW

50 Ω Input Impedance

TestLimits = 50 Ω ± 2%
