Keysight Technologies conceived of LAN Extensions for Instrumentation (LXI) in 2005 as a way to enable test and measurement interfaces using web servers in conjunction with Ethernet. LXI is used extensively in connecting computers and electronic test equipment, particularly oscilloscopes. Local Area Network (LAN)-enabled instruments can connect to a computer, using as a medium the […]
Modulated RF power amplifiers for EMC pre-compliance testing
The TekBox TBMDA3 and TBMDA4 Modulated Wideband Power Amplifiers have been specifically designed to provide an economical signal source for immunity testing of electronic circuits and products. While these amplifiers are intended to increase the output of a spectrum analyzer’s tracking generator, they are also useful as general-purpose wideband RF signal amplifiers. The TBMDA3 and […]
Arbitrary function generators billed as most affordable 16-bit AFGs
The DG800 and DG900 Series of arbitrary function generators come standard with 16-bit Resolution, an intuitive touch display, a silent fan-less design, and new advanced signal generation capabilities. The DG800 Series targets those needing signal generation from 10-35 MHz. With a starting price of just $279 the DG800 represents the most affordable 16-bit generator on […]
Cases designed for mounting 19-in. subracks, chassis, and front panels
A new 19-in. mini-rack version of the advanced TECHNOMET table-top instrument enclosures are designed for mounting standard 19-in. subracks, chassis and front panels. Applications include test and measurement equipment, networking and communications devices, sound and studio systems, laboratory instruments, industrial computers and control systems. These elegant and ultra-modern enclosures combine diecast aluminum front and rear […]
Rugged parallel optical transceivers hit 10+ GB/sec
New ParaByte transceivers are rugged parallel optical devices capable of realizing 10+ GB/sec while also meeting standards for rugged performance. Through the addition of this high-speed transceiver, TE is now a one-stop source for rugged fiber optic (RFO) solutions. The ParaByte transceiver’s parallel 12-fiber ribbon cable design is mateable and helps support speeds of up […]
The basics of simulating radar signals with AWGs
Radar is quite simple in concept, but it becomes highly complex in actual implementation. Many decades passed between the time it was first envisioned and when useful working models emerged, which happened just in time to save England from total defeat in the 1940s. When it comes to testing radar, the situation has become easier […]
A test setup that simulates automotive radar
Jungik Suh from Keysight recently took us through a simulation of an automotive radar system, a hot topic these days thanks to work being done in autonomous vehicles. The point of simulating a radar signal is to provide a test signal for downstream electronics that will act on what shows up in the radar return. […]
Test bed demo: Getting ready for emerging millimeter wave applications
We recently talked with Greg Jue from Keysight who took us through a demo of an R&D test bed for emerging millimeter wave applications. Specifically, as an application example, Jue set up an example 802.11ay system. The 802.11ay spec is designed as an improvement of the 802.11ad WLAN definition that will have a frequency of […]
Making noise figure measurements with handheld analyzers
We recently were able to get with Roland Zhang from Keysight who took us through a noise figure measurement system that really comes in handy if you’re doing 5G measurements in the field. Zhang explains that in the 5G arena there will be a lot of amplifiers or up and down converters to convert signals […]
Instrumentation that measures differential noise in real time
We were recently able to speak with Pat Murray from Anritsu who demonstrated instrumentation that computes differential noise figure. Though noise figure is a well-known parameter, differential noise figure isn’t as commonly used. But it is becoming important for the verification of low-noise amplifiers (LNAs) and other devices used in the front-end of 5G and […]
