Attaching the Reference Antenna - mmWave OTA Validation Test Reference Architecture https://www.ni.com/documentation/en/mmwave-ota-validation-test-reference-architecture/latest/user-manual/attaching-reference-antenna/
The reference antenna verifies the functionality and integrity of the system during system calibration and ensures that the system is ready for testing your DUT. Mount the reference antenna to the azimuth ...

Connecting Internal RF Cables - mmWave OTA Validation Test Reference Architecture https://www.ni.com/documentation/en/mmwave-ota-validation-test-reference-architecture/latest/user-manual/connecting-internal-cables/
Connect one end of two 2.4 mm (m)-to-2.4 mm (m) cables to the interior chamber rear bulkhead 1A and 2A ports. Route the opposite end of the cables through the correct locations on the positioner, as shown ...

Getting Started with Step-by-Step Position Sweeping - mmWave OTA Validation Test Reference Architecture https://www.ni.com/documentation/en/mmwave-ota-validation-test-reference-architecture/latest/user-manual/step-by-step-position-sweeping/
With step-by-step position sweeping, sweeping is exclusively controlled by the test execution engine which consumes a list of predefined positions and sequentially performs a measurement at each point. ...

Attaching the Measurement Antenna - mmWave OTA Validation Test Reference Architecture https://www.ni.com/documentation/en/mmwave-ota-validation-test-reference-architecture/latest/user-manual/attaching-measurement-antenna/
Mount the measurement antenna to the measurement antenna fixture as shown in the following figure. Measurement Antenna FixtureAlignment KnobAlignment KnobMeasurement Antenna1.85 mm (m)-to-1.85 mm (m) Cable, ...

Aligning the Antennas - mmWave OTA Validation Test Reference Architecture https://www.ni.com/documentation/en/mmwave-ota-validation-test-reference-architecture/latest/user-manual/aligning-the-antennas/
Antenna alignment improves the repeatability and accuracy of your test. The reference antenna data assumes that the antennas are perfectly aligned, so alignment must be performed for each antenna setup. ...

Getting Started With Autonomous Position Sweeping - mmWave OTA Validation Test Reference Architecture https://www.ni.com/documentation/en/mmwave-ota-validation-test-reference-architecture/latest/user-manual/autonomous-position-sweeping/
With autonomous position sweeping, the measurement initiation is triggered by the positioner instead of the test execution engine. This mode drastically reduces test time. The motor control sends a digital ...
