Agilent/Keysight L2053XA

The Keysight L2053XA is a LAN-based wide dynamic range average power sensor for precision RF and microwave measurements from 10 MHz to 33 GHz. It delivers real-time power measurements across a -70 dBm to +26 dBm dynamic range with zero dead time during continuous pulse sequences. The sensor supports up to 50,000 readings per second and features deep 1 MB memory with variable sampling up to 1 MSa/s, enabling detailed analysis of modulated and pulsed signals in development, validation, and production test environments.
