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.
WiMAX and 3GPP LTE support
Test one technology or a combination.
Support for 400 MHz to 4 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.
Buffer or streaming
true air capture
Capture up to 25 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 anomalies.
