Accelerate your production throughput with Keysight Technologies, Inc. U2020 X-series USB peak and average power sensors. These sensors provide the high performance and feature needed to satisfy the requirements of many power applications in R&D and manufacturing, offering a fast measurement speed of > 25,000 readings/second to reduce testing time and cut the cost of test.

The U2020 X-series comes with two models:

• U2021XA (50 MHz to 18 GHz)
• U2022XA (50 MHz to 40/50 GHz)

Get the peak power measurement capability of a power meter in a compact, portable form with the Keysight U2020 X-series USB power sensors.

The U2020 X-Series has a wide 30 MHz video bandwidth and an 80 M-sample/s continuous sampling rate for fast, accurate, and repeatable RMS power measurements. With its high-frequency coverage of 50 GHz, wide dynamic range, and extensive measurement capability, the X-Series is optimized for aerospace/defense, wireless communication (LTE, WCDMA, GSM), and wireless networking applications (WLAN).

An external trigger enables the accurate triggering of small signals close to the signal noise floor. The U2020 X-series USB power sensors come with a built-in trigger in/out connection, allowing you to connect an external trigger signal from a signal source or the device-under-test directly to the USB sensor through a standard BNC to SMB cable. The sensors also come with recorder/video-output features.

Begin testing faster; the U2020 X-series USB power sensors come with built-in radar and wireless presets for DME, GSM, EDGE, CDMA, WCDMA, WLAN, WiMAX, and LTE.

The U2020 X-Series also supports external trigger in average-only mode.

The external trigger can be used to synchronize the measurement capture with signal burst timing. By adjusting the aperture size and trigger delay, users have greater control on which portion of the waveform is being measured. This function complements the time-gated function in normal mode (peak mode) by offering a wider power range and faster measurement speed, although it comes without trace display.

Auto burst detection helps the measurement setup of the trace or gate positions and sizes and triggering parameters on a large variety of complex modulated signals by synchronizing to the RF bursts. After successful autoscaling, the triggering parameters such as the trigger level, delay, and hold-off are automatically adjusted for optimum operation. The trace settings are also adjusted to align the RF burst to the center of the trace display.

The U2020 X-Series can measure up to 20 pulses. The measurement of radar pulse timing characteristics is greatly simplified and accelerated by performing analysis simultaneously on up to 20 pulses within a single capture. Individual pulse duration, period, duty cycle and separation, positive or negative transition duration, and time (relative to the delayed trigger point) are measured. The U2020 X-Series also supports automatic pulse tilt (or droop) measurements via the SCPI command.
