Keysight Technologies has announced the U2040 X-Series of wide dynamic range power sensors, consisting of four USB models for wireless and radar applications, and a dedicated LAN model for satellite testing. This series of sensors have an extremely wide dynamic range and high measurement speeds that enable them to make accurate and repeatable power measurements.
The U2040 X-Series has a 96 dB dynamic range, spanning -70 dBm to +26 dBm enabling accurate power measurements of very small signals, critical for applications such as wireless chipset and power amplifier module manufacturing. With the new average mode time selectivity feature, users are able to make both average and time selectivity average power measurements across the full 96 dB dynamic range. This is a significant improvement when compared to conventional power sensors, which often limit time-gated dynamic range measurements at around 50 dB.
One of the most notable features of the U2040 X-Series is its measurement speed of 10,000 readings per second in fast/buffer mode. This speed enables the sensors to measure continously in real time. Conventionally sensors only provide a snapshot of continuous pulses, leaving dead time where glitches can slip by unnoticed. This speed is almost 10 times greater than existing power sensors from Keysight and other companies, enabling continous measurement.
The U2040 X-Series provides broadband coverage for any modulated signal, and covers all common wireless signal formats such as LTE, LTE-Advanced with 100 MHz bandwidth, and WLAN 802.11ac with 80/160 MHz bandwidth. Built-in radar and wireless presets allow faster test set up, and for data capture and analysis, engineers can use the Keysight BenchVue software, which is bundled free of charge with each sensor.
U2049XA LAN Power Sensor:
The U2049XA LAN power sensor achieves a number of industry firsts: 1) it is the world’s first thermal vacuum compliant (TVAC) power sensor; and 2) it is the first power sensor to come with LAN/Power over Ethernet (PoE) connectivity.
U2049XA sensors with the thermal vacuum compliance option are subjected to temperature cycling in a vacuum chamber, and are created using components with minimal outgassing properties. The LAN-based sensor overcomes the cable length limitations associated with USB connectivity and is suitable for distances up to 100 meters. Together with best-in-class long term drift performance and a frequency range of 10 MHz to 33 GHz, the U2049XA is ideal for fault detection and long distance, remote monitoring of satellite systems.
