DATA SHEE T U2040, U2053/63 and L2050/60 X-Series USB/LAN Wide Dynamic Range Power Sensors
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.
X-Series Power Sensor Key Features Widest dynamic range power sensor The X-Series power sensor are power sensors with the widest dynamic range of 96 dB (–70 dBm to +26 dBm). The 96 dB dynamic 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.
Time selectivity in average mode with variable aperture duration The X-Series power sensor offers a new feature called average mode time selectivity, whereby users are able to configure the aperture duration of measurement capture with reference to immediate trigger or external trigger. The aperture duration can be set from 20 µs to 200 ms with a resolution of 100 ns, a resolution low enough to cover any radio format.
20 automatic pulse parameter measurements The U2042/44/49/63 and L2061/62/63 X-Series peak and average power sensor offers simultaneous pulse parameter characterization of up to 20 pulses within a single capture. Individual pulse duration, period, duty cycle, rise time, fall time and other pulse parameters can be queried through the following SCPI codes: TRACe:MEASurement:PULSe[1-20], and TRACe:MEASurement:TRANsition[1-20].
Built-in radar and wireless presets Begin testing faster; the X-Series power sensor comes with built-in radar and wireless presets for common signals such as DME, GSM, EDGE, WCDMA, WLAN and LTE. Gamma correction In an ideal measurement scenario, the reference impedance of the power sensor and deviceunder-test (DUT) impedance should equal the reference impedance (Z0); however, this is rarely the case in practice.

With best-in-class long term drift performance, a frequency range of 10 MHz to 33 GHz and a dynamic range spanning 90 dB, the U2049XA LAN power sensor is ideal for fault detection and monitoring of satellite systems.
Performance Specifications Specification definitions There are two types of product specifications: –– Warranted specifications are specifications which are covered by the product warranty and apply over a range of 0 to 55 °C unless otherwise noted. Warranted specifications include measurement uncertainty calculated with a 95% confidence. –– Characteristic specifications are specifications that are not warranted. They describe product performance that is useful in the application of the product.

Noise multipliers The measurement noise for the X-Series power sensor is dependent on the measurement mode and the time for the measurement. In general, average only mode is lower noise than normal mode, and the longer a measurement takes the lower the noise is. We will define three measurement modes and how the noise can be adjusted. Average-only mode The measurement noise due to the X-Series power sensor is dependent on the measurement time.

Calibration uncertainty Definition: Uncertainty resulting from non-linearity in the X-Series power sensor detection and correction process. This can be considered as a combination of traditional linearity, calibration factor and temperature specifications and the uncertainty associated with the internal calibration process.
