Description
Betso RF OCTOPUS
The Betso RF OCTOPUS is the smallest and world's most versatile RF splitter, combiner, and diagnostic tool ever made. This groundbreaking device supports multiple configurations, including:
- splitter 2:8 (diversity: 1 input → 4 outputs),
- splitter 1:8 (1 input → 8 outputs), and
- combiner-splitter 2:8 (combining two BNC inputs and splitting the signal into 8 outputs).
With user-selectable low-pass filters (700 MHz, 960 MHz, or 1260 MHz) directly accessible via the intuitive menu, the RF OCTOPUS is perfectly suited for worldwide applications.
Effortless Operation Anywhere
Its sunlight-readable OLED display, paired with two bright white LEDs, ensures effortless operation in any environment. Additionally, each channel features individually switchable power for active antennas, complete with overload protection and failure signalization.
The RF OCTOPUS also includes a removable belt clip that can be mounted on either the top or bottom of the chassis. Firmware updates and new features are easily accessible through the USB-C connector, which is securely sealed against dust and water.
Built-in Cable Testing for Reliable Performance
With its integrated cable attenuation measurement tool, the RF OCTOPUS simplifies cable diagnostics. Connect your RF cable between two BNC connectors, select your frequency (500–900 MHz), and instantly measure the cable’s attenuation and condition. This ensures your cables perform at their best and minimizes system interruptions.
In addition, the RF OCTOPUS can measure the output RF power of your wireless transmitter, providing a quick and reliable check to ensure your RF power output is within the expected range. Another powerful feature for a comprehensive wireless system checkup!
Main Features
