Introducing the U2000 Series USB Power Sensors

The U2000 Series enable simpler, lower-cost power measurements versus conventional power meter and sensor combinations. Now with nine high-performance models, the U2000 Series USB power sensors offer compact, high-performance solutions for today’s CW and modulated signals.

Compact “power meters”, simple set-up

The U2000 Series are standalone sensors. That means they essentially operate like power meters, just in smaller forms. No reference calibrator is required. The fact that each sensor draws minimal power from a USB port—and that it doesn’t need additional triggering modules or power adaptors to operate—makes it more portable, especially for base station testing. Setting up is easy: just plug it to the USB port of your PC or laptop—or even select network or handheld spectrum analyzer—and start your power measurements. The figure below illustrates the very simple, straightforward setup of the U2000 Series.

High accuracy

Each U2000 Series sensor provides excellent linearity, SWR and uncertainty specifications, so you can be confident in every measurement you make.

Wide range, high power

The U2000 Series’ dynamic range spans across a wide 80 dB, taking on high power up to +44 dBm.

Remote monitoring and tests

With the U2000 Series sensor plugged to a networked USB hub, you can conveniently monitor power measurements of an antenna tower from the control room, beyond the limits of USB cable lengths.

Faster production testing of multiple channels

The U2000 Series’ fast measurement speed helps reduce test time. This, coupled with the capability to enable monitoring of more than 20 channels simultaneously, is an advantage in the production line where efficiency is of utmost priority.

The U2000 Series has both internal and external zeroing capabilities. With internal zeroing, high isolation switches in the sensor are opened to isolate the sensor from the device-under-test (DUT) it is connected to. As such, you don’t need to power-off the DUT or disconnect the sensors. This speeds up testing and reduces sensor wear-and-tear.

No manual input of calibration data is required. All calibration factors, as well as temperature and linearity corrections, are stored in the sensors’ EEPROM, auto- downloaded at calibration.

Often, you’d need to automate your tests. The U2000 Series sensors are well-equipped for seamless integration to your system with industry standard SCPI compatibility. They also come with built- in triggering capability to allow receipt of external triggers from other instruments.

Transform your signal generators and spectrum analyzers into accurate power meters

You could literally have a power meter next to you—or instead, turn your Keysight signal generators, handheld spectrum analyzers or FieldFox handheld RF/Microware analyzers into a power meter for accurate power measurements. Even with the U2000 connected, you can switch between power measurements and the device’s original function at any time. You can also use the U2000 with your Keysight network analyzers for source power calibration.

Intuitive power analysis software

The U2000 Series is supported by the Keysight BenchVue software and BV0007B Power Meter/Sensor Control and Analysis app. Once you plug the USB power sensor into a PC and run the software you can see measurement results in a wide array of display formats and log data without any programming.

Diode-based sensors frequently rely on the application of correction factors to extend their dynamic range beyond their square-law region, typically in the range of –70 to –20 dBm. While this technique achieves measurement of CW signals over a wide dynamic range, it fails to do so for modulated signals when the signal level is above the square-law region. Modulated signals must be padded down, with their average and peak power levels within the diode square-law region, for accurate average power measurement.

The U2000 Series USB power sensors are true-average, wide-dynamic-range RF/ microwave power sensors, based on a dual-sensor diode pair/attenuator/diode pair topology as proposed by Szente et. al. in 1990.

This technique ensures diodes in the selected signal path are kept in their square law region — with output current and voltage proportional to input power. The diode pair/attenuator/diode pair assembly can then yield the average of complex modulation formats across a wide dynamic range, irrespective of signal bandwidth.

The dual range Modified Barrier Integrated Diode (MBID) package incorporates diode stacks in place of single diodes. This further improves measurement accuracy of high-level signals with high crest factors without incurring damage to the sensor.

Implementation of both techniques in the U2000 Series USB sensors enable effective average power measurements of a wide range of signals, including multitone and spread spectrum signals used in CDMA, W-CDMA and digital television systems.
