Newest WaveJudge Features

Four independent, configurable ports
Ideal for testing MIMO handovers and MIMO or beamforming on TDD/FDD systems.

Each port assignable as TX or RX
Configure any port as a TX or RX with a firmware download.

3GPP LTE and WiMAX support
Test one technology or a combination.

Support for 400 MHz to 6 GHz
Test in multiple spectrum bands.

Superior dynamic range and sensitivity
Accepts a wide range of power levels for each spectrum and adjusts sensitivity to accurately and reliably read strong or weak signals.

Automatic gain control
AGC per port enables field testing in challenging environments, simplifies test set up, and frees ports to test demanding applications such as handovers with MIMO and beamforming.

Buffer or streaming true air capture
Capture up to 17 seconds @ 10 MHz of wireless communication for analysis or troubleshooting, or stream to external storage device to track long-term trends or to isolate intermittent anomolies.

Baseband interfaces
Analyze and validate signal quality − essential for BBIC designers, RFIC designers and system integrators.

Flexible channel BW support
Test at any channel BW up to 20 MHz.
