Boonton 55 Series USB Peak Power Sensor Demonstration
Product: Show the time gated power measurement capabilities of Boonton 55 series wideband USB Peak Power sensor powered by Real Time Power Processing™.
Target Users:
R&D, design,systems engineers and technicians working in commercial and military applications such as WiFi, LTE-TDD, LTE-FDD, avionics, RADAR, and medical systems. Statistical analysis using gated CCDF allows average and peak power as well as crest factor measurements of a frame or any segment of an 802.11ac or LTE-TDD signal.Time domain marker measurements including average and peak power measurements as well as pulse characteristics such as overshoot, droop, risetime and intermittent behavior.
About 55 Series Wideband USB Peak Power Sensor&Real Time Power Processing™:
Key benefits of the Boonton 55 Series wideband USB peak power sensor is the processing power and real-time signal acquisition featuring NO GAPS in acquired data.
- Crest factor measurements
- 100 MSamples/second SUSTAINED sample rate – world's fastest!
- 10 GSamples/second effective sample rate for repetitive signals (superior resolution)
- Re-arm time is microseconds, versus many milliseconds or more
- Capture and analyze data 100x faster than conventional power sensors
- Real-time "video" display update rate versus a series of "snapshots"
Measuring WiFi with Real-Time Power Processing™ USB peak power analyzer:
In the demo set-up two 802.11 WiFi radios are linked via a coaxial cable and an attenuator for pathloss. Transmit signal of one of the WiFi radios is coupled and monitored by 55006 Real Time USB peak power sensor. Boonton's renowned trigger stability, waveform fidelity and superior high video bandwidth added to the Real Time Power Processing™ feature captures every detail of the WiFi signal without missing a pulse or a glitch.
