The WaveJudge strengths draw from the unique ability to combine RF analysis, Digital demodulation analysis and Protocol analysis – a powerful combination. The WaveJudge allows rudimentary testing of the signal by providing spectrum related graphs to ensure the RF quality of the signal being measured is valid. Time and frequency domain measurements are excellent tools for determining basic characteristics of the signal. This first level analysis provides you with the confidence that the signal has the correct waveform, center frequency, UL and DL bursts. You can quickly identify any Carrier and sampling clock source mismatch in the summary area and identify subchannelized signals with the Spectrogram.
In addition to RF and Digital demodulation analysis, The WaveJudge allows upper layer protocol analysis with full correlation to the PHY layer. This ability provides the advantage in wireless testing. The WaveJudge Architecture The WaveJudge architecture allows two independent channels of RX. Each of these channels have their own Radio, ADC, FPGA and DRAM. In addition the channels can be set to any frequency up to 6 Ghz and channel BW up to 20 Mhz. providing maximum flexibility in test configurations such as MIMO and handover testing. Having separate RX channels allows quick identification, thru triggering and comparing side by side, the transmissions of both DL and UL regardless if they are conflicting in time domain. Each of the RX channels also have adjustable gain controls which can aid in environments where the noise floor of the DL is comparable to the signal level of the UL. Additionally FDD configurations with separations of more the 200Mhz can be tested by using each channel for UL and DL traffic while supporting multiple frequencies simultaneously. Test diversity schemes using the 2 independent RX paths which allow full decode analysis to verify Maps and discover relative timing shifts.
The WaveJudge Protocol AnalyzerThe WaveJudge Protocol Analyzer contains a technology matching cross-layer decode ability including the PHY, L2 and L3 layers. The cross correlation engine provides views at any interval within the capture, which enables understanding between PHY layer anomalies and upper layer throughput issues. For each PDU you can customize your view to include pertinent LTE or WiMAX measurements including RCE, FEC errors, CINR, RSSI, CRC and HCS errors. These insightful views from theWaveJudge include the ability to:• Capture, filter and decode the entire MAC-layer message structure and associated IP source/destination information.
