Test system validates 400GE networks and devices

February 16, 2021 By Lee Teschler

The new AresONE-S 400GE test system enables network equipment manufacturers and data center operators to validate complex, mixed 400 gigabit Ethernet (GE) and lower-speed networks and devices. Data center operators have widely deployed mature 100GE non-return-to-zero (NRZ)-based technologies. However, higher Ethernet speeds, such as 400GE, create new mixed signaling and forward error correction (FEC) implementations […]

Reference design based on 4-kW high-efficiency single-phase ac-dc evaluation board

February 10, 2021 By Lee Teschler

A new power supply reference design enables engineers to identify and correct design errors before building hardware, thereby lowering product costs and speeding time to market. Switched-mode power supplies provide greater efficiency, increased power density and lower overall system costs when using GaN devices. However, GaN, a high switching speed, high performance wide bandgap semiconductor, […]

Basics of QAM reception and its measurement

December 3, 2020 By dherres

A conventional AM broadcast generally begins in the studio as a music or voice audio signal. The audio signal modulates the amplitude of a radio-frequency electrical signal. This AM signal–also referred to as double-sideband amplitude modulation to distinguish it from single-sideband modulation–produces equal frequency sidebands on either side of the center frequency. In single-sideband modulation […]

The back and forth of interferometer technology

September 15, 2020 By dherres

Conceptually, the interferometer is a relatively simple instrument that compares two distances typically differing only by a slight amount. Two waves, often coherent light waves, reflect from standard mirrors mounted at the object under investigation. The light from one mirror passes through a half-silvered mirror while the light from the other reflects from the back […]

The complexity of wireless receiver testing

June 3, 2020 By Lee Teschler

Eric Hsu | Keysight Technologies, Inc. The demand for wireless communications now challenges the physical limitations of today’s wireless communications systems. Interference can easily arise when systems operate in a crowded wireless environment using a shared spectrum. Signal congestion makes the process of designing, testing, and isolating system problems more complex. In the next few […]
