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 […]

Portable pocket stroboscope includes auto-sync laser function
The RT STROBE pocketLED Laser combines an LED-stroboscope and a laser tachometer in one device. The LED stroboscope is used for the visualization of movement. The laser tachometer enables contactless rotational speed measurement. The areas of application include checking turbines, production and process control in the printing and textile industries,and inspection of running equipment in […]
New probe expands high-voltage meter range to 140k Vdc/100k Vac
The HVL-150 SmartProbe expands the measurement range of the Model 4700 Precision High-Voltage Meter to 140 KVdc/ 100 KVac(rms). The HVL-150 benchtop probe features Vitrek’s proprietary ultra-low thermal coefficient attenuator technology that minimizes the effects of self-heating to maintain optimum accuracy. In addition, the probe’s low capacitance enhances AC measurement performance. The Vitrek 4700 HV […]
Handheld base station analyzers make passive intermodulation measurements
PIM over CPRI software lets BTS Master MT8220T and MT822xB handheld base station analyzers make passive intermodulation (PIM) measurements from the ground for the first time. By eliminating the need for network operator installation and maintenance crews and contractors to climb the tower to test for PIM, the new BTS Master-based solution is a much […]
Digitizers work up to 60 MHz over 48 channels
Twelve new LXI-based digitizerNETBOX data acquisition instruments are designed specifically for situations where multiple signals need to be acquired, stored and analyzed. Users can select from models that provide 24, 32, 40 or even 48 fully synchronized channels. The new DN6.59x series digitizers are all based on the latest high-resolution 16-bit ADC technology and come […]
Signal analyzers get 5G NR software packages
Three software packages now run on the Antritsu Signal Analyzer MS269x series to support measurements of RF Tx characteristics of 5G New Radio (NR) base stations and mobile devices. Installing the 5G Measurement Software (MX269051A) and NR TDD sub-6-GHz options (MX269051A-011 and MX269051A-061) in the signal analyzers creates a cost-efficient and flexible solution for chipset […]
Making measurements with Matlab
Matlab was released in 1984 by Mathworks, an American privately-held corporation whose other major product is the closely-related Simulink. Additionally, Mathworks offers close to 100 other programs, such as Polyspace, SimEvents and Stateflow. Matlab’s main focus is numerical computing, including matrix and algorithm operations, plotting of data and functions and creation of user interfaces. It […]
Test platform supports MediaTek 5G chipset development and verification
MediaTek Inc. and Anritsu Corp. have agreed to forge a partnership for 5G development and physical layer verification. MediaTek Inc. selected Anritsu’s Radio Communication Test Station MT8000A as a prioritized test platform for the verification of standard-based 5G NR chipsets targeting upcoming global 5G deployment. Anritsu, a leader in mobile communications testing, will support MediaTek’s […]
Measuring signals on transmission lines
Reflections typically arise when a beam of light strikes a polished flat reflective body whose surface is perpendicular to the beam of light. Then the transmitted light minus loss in two-way transit appears at the source. This is similar but not exactly equivalent to an electrical signal traveling through a conductive medium that has an […]
