USB, LAN power sensors offer world’s widest dynamic range

The U2040 X-Series offers a dynamic range of 96 dB, spanning -70 dBm to +26 dBm. This enables accurate power measurements in applications such as wireless chipset and power amplifier module manufacturing. The sensors also have an average mode time selectivity feature which enables users to make both average and time selectivity average power measurements across the full 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.

With a measurement speed of up to 10,000 readings per second in fast/buffer mode, the U2040 X-Series measures continuously in real time and keeps pace with very fast pulses, up to 10 kHz pulse repetition frequency (PRF). The new sensors measure every continuous pulse without leaving time gaps in between measurement acquisitions. In contrast, conventional sensors only provide a snapshot of continuous pulses, leaving dead time where glitches can slip by unnoticed.

The U2040 X-Series provides broadband coverage for any modulated signal, and covers the most relevant 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.

The U2049XA LAN power is the world’s first thermal vacuum compliant (TVAC) power sensor. At the same time it is the first power sensor to come with LAN/Power over Ethernet (PoE) connectivity. The sensors have been subjected to temperature cycling in a vacuum chamber, and are created using components with minimal outgassing properties. Since this sensor is LAN-based, it overcomes the cable length limitations associated with USB connectivity and is suitable for distances up to 100 meters. 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.
