Keysight U2040 & U/L2050/60 X-Series USB/LAN Wide Dynamic Range Power Sensors

Accurately measure any modulated signal with the U2040 & U/L2050/60 X-Series USB/LAN power sensors. With LAN or USB connectivity, the U2040 & U/L2050/60 X-Series sensors come with the world’s widest dynamic range in a power sensor, covering a range of -70 to +20/26 dBm. The U2049XA and L2065XT LAN power sensors comes with a thermal vacuum option, and it gives the same accuracy and performance even in thermal vacuum chambers.

Typical test setup for wireless chipset manufacturing test

Three power sensors are used to measure the chipset’s input power, output power, and reflected power. A spectrum analyzer, like the Keysight Technologies MXA, is used to measure other critical parameters such as ACPR, EVM, and harmonics. Care should be taken to ensure that the power to be measured does not exceed the sensor’s measurable power range to avoid damaging the sensor, particularly at the power amplifier’s output. Depending on the signal formats, a trigger output signal from the signal source can be connected to the trigger input ports of the power sensors to synchronize the signal timing and sensors’ measurement acquisitions.

Average mode time-selective measurement

The average mode time-selectivity feature allows you to precisely select when a measurement is made. A measurement aperture is used to define the duration of the measurement and its position in time can be set relative to a trigger. The aperture duration can be set from 20 μs to 200 ms with a resolution of 100 ns to be able to cover any radio format. Giving you similar ability to define a measurement as timegated power measurements in peak mode, this function allows you to control which portion of the waveform is measured, and perform precise time-selective average power measurements across the full 96 dB dynamic range, and real time measurements of up to 50,000 readings per second.
