RF testing method and testing system

An RF testing method for an RX test, applied between a testing instrument and multiple devices under test (DUTs) at least comprising a first DUT and a second DUT, wherein the testing instrument comprises a signal generator and a signal analyzer, the method comprising:

• sending a first sync signal to the testing instrument and both the first DUT and the second DUT;
• and
• the testing instrument sending a downlink signal to both the first DUT and the second DUT;
• the first DUT and the second DUT processing the downlink signal from the testing instrument;
• and
• receiving acknowledgement signals from both the first DUT and the second DUT.

A testing system, comprising:

• a testing instrument, comprising a signal generator and a signal analyzer;
• multiple devices under test (DUTs), at least comprising a first DUT and a second DUT, and electrically connected to the testing instrument;
• a host device, electrically connected to the testing instrument and the multiple DUTs;
• wherein,
• the host device sends a first sync signal to the testing instrument and the first DUT, so that the first DUT occupies the signal generator to receive a testing signal from the signal generator;
• the first DUT sends an uplink signal to the signal analyzer based on the testing signal to occupy the signal analyzer for signal analysis at a first point in time;
• the host device sends a second sync signal to the testing instrument and the second DUT, so that the second DUT occupies the signal generator to receive the testing signal from the signal generator at a second point in time;
• and
• the first point in time is parallel to the second point in time.
