About 5¬5 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.
- Data buffer capabilities provides real-time average, max and min power levels of each Wi-Fi burst or pulsed RADAR signal making ideal for compliance testing and logging.
- 195 MHz VBW supports 160 MHz 802.11ac and LTE signals
- 100 MSamples/second SUSTAINED sample rate – world’s fastest!
- 10 GSamples/second effective sample rate for repetitive signals (superior resolution)
- 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:
Two 802.11Wireless Access Point (WAP) radios are linked via a coaxial cable and attenuators for path loss. Transmit signal of one of the WiFi radios is tapped of 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.

Existing and Comparable Products:
- Replace systems that require crystal detector, a digital oscilloscope, a spectrum analyzer, an average power meter, and assorted connectors & couplings to monitor a single output.
- Multisensor configuration enables simultaneous measurements of forward & reflected power (Return Loss), and amplifier input & output (Gain).
