Test set measures WLAN DUT performance in actual operating conditions

April 21, 2017 // By Jean-Pierre Joosting
Anritsu Company has announced a Network Mode for its MT8862A wireless connectivity test set , which is an instrument capable of supporting various WLAN protocol standards such as IEEE802.11ac/n/a/g/b.

This makes the MT8862A capable of measuring the performance of an 802.11ac-capable WLAN device under test (DUT) in the actual operating state. With the Network Mode configuration, the MT8862A serves as a more efficient manufacturing test solution to verify WLAN chipsets designed into smartphones, smart home electronics, connected cars, and IoT systems, which eventually entails into faster time to market and lower testing cost.

RF performance characteristics, such as Tx power and Rx sensitivity (PER), as well as waveform coverage range can be measured over-the-air (OTA) using the Network Mode, which eliminates the need for dedicated vendor-provided test modes typically required for WLAN device verification. Removal of a physical connection establishes a more accurate representation of the actual DUT performance in a real-world environment, as the measurements take into consideration the effect of the internal wireless antennas.

The MT8862A can be operated remotely via web browser from a control PC connected by Ethernet. This configuration simplifies conducting measurements by eliminating more complex setups, for more efficient testing.
