The Keysight L2051XA is a LAN-based wide dynamic range average power sensor for precise measurement of modulated signals from 10 MHz to 6 GHz. This standalone instrument delivers 50,000 readings per second across a dynamic range of −70 dBm to +26 dBm, eliminating the need for external power supplies or triggering modules. Power is supplied via PoE (IEEE 802.3af or 802.3at Type 1) over a single LAN cable, enabling remote operation up to 100 meters away. The sensor features a web browser interface with virtual front panel control, internal zero and automatic calibration, and built-in trigger input/output. Type N (male) connectors interface with the measurement system.
