Model 12100 Series | 9 kHz to 67 GHz Average RF Power Sensors
The Model 12100 Series RF power sensors measure average power from 9 kHz to 67 GHz with a dynamic range of -60 dBm to +26 dBm. These compact sensors provide true RMS measurements across all modulation formats, including CW, pulsed, and complex modulated signals, without requiring pre-use calibration.
Key Features of These RF Power Sensors
- Broad Frequency Coverage: Continuous operation from 9 kHz to 67 GHz, supporting microwave and mmWave applications.
- Wide Dynamic Range: Accurate readings from -60 dBm to +26 dBm with high linearity across the full range.
- True RMS Detection: Reliable average power measurement regardless of waveform shape or modulation type.
- Plug-and-Play Design: USB-powered sensors connect directly to a PC or laptop—no external power supply or warm-up needed.
- Deep Internal Memory: Stores measurement data for extended logging or post-processing in field or lab environments.
- PowerEye Software & API: Intuitive Windows-based software included; full API support for integration into automated test systems (LabVIEW, MATLAB, Python, C++ examples available).
- Compact & Portable: Small form factor suits benchtop use, production testing, field maintenance, and ATE racks.
These RF average power sensors are suited for applications such as radar transmitter verification, 5G/6G base station output checks, satellite communication link testing, electronic warfare system calibration, amplifier gain measurements, and general microwave component evaluation where accurate, modulation-independent power readings are required.
