Accurately measure any modulated signal with the Keysight Technologies, Inc U2040, U2053/63 and L2050/60 X-Series USB/LAN
wide dynamic range power sensor. With LAN connectivity, a first in the industry, and USB connectivity, the U2040, U2053/63 and
LAN connectivity, the L2050/60 X-Series comes with the world’s widest dynamic range in a power sensor, covering a range of –70 to
+26 dBm. And because the U2049XA LAN power sensor is thermal vacuum qualified, you can get the same accuracy and performance
even in thermal vacuum chambers.
