Making Uncalibrated Measurements with the PXIe-5632

Performing uncalibrated measurements with the PXIe-5632 can be useful for measuring device raw performance, custom measurement configuration, and other specialized measurements. You can perform uncalibrated measurements using the NI-VNA Soft Front Panel (SFP) or the NI-VNA driver API.
  1. Prepare for the measurement.
    1. Warm up the device and the DUT as specified in the device specifications.
    2. Make signal connections as directed in the Connecting Signals section.
    3. Verify that the device is within the factory calibration interval.
  2. Set up an initial, uncalibrated measurement.
    1. Preset the PXIe-5632.
    2. Configure the source parameters, including reference frequency, output power, and IF bandwidth.
    3. Connect the DUT to verify setup, cables, adapters, and operation.
    4. Select which S-parameter(s) to measure, and choose the display format.
  3. Start the measurement.
  4. Observe the uncalibrated response.
  5. Remove the DUT.
