U2040 X-Series Key Features
Widest dynamic range power sensor
With a dynamic range spanning from –70 dBm to +26 dBm, the U2040 X-Series comes
with the widest dynamic range found in a power sensor. The 96 dB range enables
accurate power measurements of very low signal levels for a broad range of applications
such as wireless chipset, power amplifier and module manufacturing, satellite payload
testing, test system or instrument calibration, and radar pulse parameter measurements.
The U2042XA, U2044XA and U2049XA are able to support up to 4 pairs of gate power
measurements.
Super-fast measurement speed
The U2040 X-Series takes up to 50,000 super-fast readings per second (in fast/
buffer mode/average mode), a ten times improvement over Keysight’s previous sensor
offerings, allowing test engineers to increase test throughput capacity and reduce cost
of test especially in high volume manufacturing environments such as mobile chipset
manufacturing.
This measurement speed is fast enough to measure every continuous pulse without
leaving time gaps in between measurement acquisitions. While conventional sensors
only provide a snapshot of continuous pulses, leaving dead time where a glitch could slip
by unnoticed, the U2040 X-Series measures continuously in real time and keeps pace
with very fast pulses, up to 10 kHz PRF. Users are also able to fully control which portion
of the signal is measured and what throughput they can expect because the aperture
duration precisely defines the maximum measurement speed as 1/aperture duration. For
example, setting the aperture duration to 20 μs offers 20 μs of measurement time per
reading, equaling a measurement speed of 50,000 readings per second.

Broadband coverage for any modulated signal formats
The U2040 X-Series makes accurate average or time-selective average power measure-
ments of any modulated signal, and covers all common wireless signals such as LTE,
LTE-Advanced with 100 MHz bandwidth, and WLAN 802.11ac with 80/160 MHz band-
width. A 4-path diode stack design with parallel data acquisition paths offers seamless
range transition with high accuracy and repeatability. This design enables all the diodes
to operate in their square law region, allowing the U2040 X-Series to function like
thermocouple power sensors to provide accurate average or RMS power for broadband
modulated signals.
