The Keysight L2057XA is a LAN-connected wide dynamic range average power sensor engineered for precise power measurements from 10 MHz to 67 GHz. It delivers up to 50,000 readings per second with internal zero and automatic calibration to minimize measurement uncertainty. The sensor accurately measures modulated signals across demanding R&D, manufacturing, and laboratory applications where speed and repeatability are essential.
