Wireless Test Systems for Automated Validation
The WTN series puts Wi-Fi and Bluetooth test stations into one instrument: four independent channels in a 19-inch, 1 HU chassis, or a single channel in a compact half-width unit. Each channel works as a Wi-Fi station, access point or monitor and as a Bluetooth device, with direct RF access through SMA ports, and every function is controlled from your test system.
Features
Independent channels
Each channel runs its own test. Start, stop and configure channels separately, from one client or several.
Station, access point, monitor
Join the device under test as a client, host an access point for it, or capture frames passively.
Measurements with timestamps
Received level per network, client, frame and chain, link parameters, throughput and connection events.
Bluetooth on every channel
Classic and Low Energy discovery, pairing, GATT and Direct Test Mode. Bluetooth 6.0 Channel Sounding as option.
Calibrated RF option
Factory calibration of output power and received level per port and band, with a calibration certificate.
Fits your test system
Python and LabVIEW instrument drivers, REST and gRPC over LAN or USB, NI TestStand and pytest support.
