Transistor-transistor logic (TTL) and complementary metal oxide semiconductor (CMOS) logic are the principal types of integrated circuit-based logic gates implemented in digital circuitry. TTL employs bipolar junction transistor technology while CMOS uses the field-effect transistor concept at the input. TTL consumes far more power than CMOS, which is one reason CMOS has eclipsed TTL as […]
Test and Measurement Tips
Samsung to use Anritsu signal analyzer for 5G System Development
Samsung Electronics Co., Ltd. will use the Anritsu MS2850A Signal Analyzer with 5G analysis software installed to support 5G system developments. Samsung unveiled its end-to-end 5G product portfolios, including 5G home routers (CPEs) and 5G Access Unit (AU), last year under development for commercial-grade products. The company is engaged with major operators in leading markets […]
mm-Wave testbed helps validate first commercial 5G NR active array antennas at 26 GHz
Ball Aerospace and Anokiwave have validated the first commercial 5G NR active array antenna product designs in the 26 GHz band using the Keysight 5G NR-ready measurement testbed. The use of phased arrays at mmWave frequencies requires over-the-air (OTA) testing as well as spatial beam measurements. Keysight metrology-grade test equipment offers the sensitivity necessary to […]
Basics of measurement resolution
In electronic instrumentation, resolution is a measure of the distance in amplitude at which we can distinguish between two points on a waveform. This is not the same as accuracy, which is a measure of how closely a waveform as displayed or measured agrees with the signal at the instrument’s input. One of the principal […]
Data acquisition software allows thermocouple/voltage measurement without programming
EXLab Express is data acquisition software that is a version of EXLab data acquisition software from AMETEK VTI Instruments. It allows users of the EX1401 Thermocouple/Voltage Measurement Instrument to acquire data without programming. It simplifies instrument configuration, acquisition and data display without sacrificing functionality or performance. Using EXLab Express, users will be up and running […]
Keysight Technologies receives certification for eCall test emulator software
The Keysight E6951A public safety answering point (PSAP) emulator has been certified by NavCert GmbH. The E6951A is part of Keysight’s E6950A eCall Conformance Test Solution. The certification was awarded Dec.18, 2017. EU-Regulation 2015/758 states that beginning April 1, 2018, eCall in-vehicle system (IVS) functionality must exist in all new types of vehicles in categories […]
Making measurements on balanced transmission lines
Stray electrical fields are everywhere. They infiltrate signal transmitting and receiving devices as well as the transmission lines that connect them, taking the form of noise and unwanted signals. The effect is to raise the signal to noise ratio, obscuring desired analog and digital information. There are mitigation techniques, but to be effective they must […]
Instrumentation turns low-frequency noise measurements into math models
The new Advanced Low-Frequency Noise Analyzer (A-LFNA) and WaferPro Express software let designers measure noise more accurately. WaferPro Express software comes out of a collaboration among Keysight Technologies and research centers, such as Sweden’s Chalmers University, Germany’s Fraunhofer EMFT, Belgium’s IMEC, and France’s LAAS-CNRS. The Keysight A-LFNA now provides designers the flexibility to transform their […]
VIDEO: Domains in the Tektronix MDO3000 Oscilloscope
An overview of time and frequency domains and demonstration of the Spectrogram. Hi again and welcome to our 85th Test and Measurement Video. Today we’ll talk about domains in the Tektronix MDO3000 oscilloscope. By way of background, in mathematics a function is frequently graphed in Cartesian coordinates. Two axes intersect at right angles at the […]
