Over the air measurement system and method
An over-the-air measurement system is provided for analyzing a device under test. The over-the-air measurement system includes a first measurement unit, a first antenna connected to the first measurement unit, a second measurement unit, and a second antenna connected to the second measurement unit. The first measurement unit is configured to establish a communication link, within a communication link frequency range, to the device under test via the first antenna. The second measurement unit is configured to measure radio frequency radiation, within a measurement frequency range, of the device under test via the second antenna. The communication link frequency range and the measurement frequency range do not overlap each other.
