LadyBug Technologies LBSF09L True-RMS RF Power Sensor

The LBSF09L sets a new benchmark for precision RF power measurement, covering 9 kHz to 9 GHz with industry-leading accuracy. Its thermally stable, multi-path RMS architecture delivers outstanding measurement uncertainty across an 83 dB dynamic range, providing faster response and greater sensitivity than traditional thermal sensors. Each unit is Tier 1 traceable to NIST or METAS, ensuring trusted results.

Key Features

• Patented NoZero® / NoCal® technology – Eliminates user zeroing and calibration drift for stable, continuous measurements across 0°C–55°C.

• Flexible connectivity – Standard USBTMC + USB HID interfaces, with optional HiSLIP LAN (PoE-ready), SPI, and I²C for automated and embedded systems.

• < 1.1:1 typical VSWR – Ensures excellent matching and low reflection.

• Precision SMA male RF connector – Built for reliability and repeatability.

• PMA-12 Power Meter Software included – Supports SCPI commands (READ?, FETCH?) and advanced time-domain trace analysis.

• Optional low-temperature capability – Extends operation to -55°C for demanding environments.
