Agilent/Keysight L2054XA

The Keysight L2054XA is a LAN-based wide dynamic range average power sensor engineered for RF and microwave measurement across demanding automated test systems and laboratory environments. Operating from 10 MHz to 40 GHz with a measurement range of −70 dBm to +20 dBm, this sensor delivers 50,000 readings per second with zero dead time during continuous pulse measurements. Its broad dynamic range accommodates both small-signal and high-power characterization without requiring range switching.
