Keysight U2040 X-Series User’s Guide
Overview
The U2040 X-Series wide dynamic range power sensors consist of four USB models and a
LAN model:
– U2041XA USB wide dynamic range average power sensor (10 MHz to 6 GHz)
– U2042XA USB peak and average power sensor (10 MHz to 6 GHz)
– U2043XA USB wide dynamic range average power sensor (10 MHz to 18 GHz)
– U2044XA USB peak and average power sensor (10 MHz to 18 GHz)
– U2049XA LAN power sensor (10 MHz to 33 GHz, LXI Class C compliant)
The U2040 X-Series is capable of measuring the average and peak power of modulated,
pulsed, and continuous wave (CW) signals in 10 MHz to 33 GHz frequency range and
–70 dBm to 26 dBm power range.
The U2049XA is capable of long distance remote monitoring of up to 100 meters via the
Power over Ethernet (PoE)/LAN connectivity. The PoE connectivity is compliant to the IEEE
3 W, 802.3af or 802.3at Type 1 standard.
The U2049XA is provided with two options; Option 100 and Option TVA. Option TVA is a
thermal vacuum option for use within a thermal vacuum (TVAC) chamber.
NOTE
The typical LAN port on your PC or Keysight instruments is not able to power up the
U2049XA. The U2049XA must be connected to a PoE port, which supplies the DC power
required to power up the U2049XA and to transfer data.
CAUTION
Ensure that the U2049XA Option 100 is covered with the LAN sensor casing provided to
meet performance specifications during operation. It is strongly recommended not to
remove the sensor casing.
CAUTION
As the U2049XA Option TVA is fully enclosed in metal, it is strongly recommended to mount
it on a cooling plate (with the thermal interface material provided) during operation to
avoid overheating. Refer to “
for more
information.
