Agilent/Keysight L2055XA

The Keysight L2055XA is a LAN-connected average power sensor engineered for precision characterization of modulated RF signals across demanding test environments. This X-Series instrument delivers 50,000 readings/second measurement speed with a wide dynamic range spanning −70 dBm to +20 dBm (10 MHz–50 GHz), making it ideal for low-level signal detection and time-selective average power analysis.
