The Keithley DMM7512 dual channel 7½-digit sampling multimeter packs two independent and identical digital multimeters into a low profile 1U high, full rack width space-saving enclosure. The DMM7512 targets a range of demanding high-volume manufacturing test applications that require measurement capacity, performance and a compact footprint. Currently, all other 7 ½-digit, high accuracy DMMs provide […]
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 […]
PC-based board tester finds PCB faults quickly
The ABI BoardMaster-RM Universal PCB Test system is housed in a convenient 19-in. rack case. It is an all-in-one unit featuring a comprehensive set of test instruments, complete with a built-in Windows 10 PC and special software for testing and fault-finding on almost any kind of PCB and assembly. Numerous valuable investigation methods are provided, […]
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 […]
Handheld measurement instruments let IoT network operators check conditions in the real world
New Nemo IoT Meter and Nemo Handy IoT instruments enable network operators and service providers to actively test networks in the field, ensuring the coverage and service quality of networks in the mission-critical and consumer-based Internet of Things (IoT) applications, accelerating installations, and speeding time-to-revenue. “The availability of LTE network coverage does not necessarily mean […]
Megohmmeter measurements and instrumentation for insulation testing
Megohmmeter measurements can now be more accurate, rapid and safer than ever before. JEFF JOWETT, MEGGER A considerable number of electronics personnel working throughout the electrical industry are military trained. And many of them learned on a simple hand-cranked analog meter, properly termed a megohmmeter, or insulation tester. These testers were typically 500-V units that […]
Functions and features of advanced hipot testers
Modern instruments help to check whether manufactured equipment meets the proliferating variety of international safety standards that govern factors such as grounding and the ability to withstand overvoltages. KEVIN CLARK, VITREK, INC. Electrical safety testers – often referred to as hipot testers – are an integral part of electrical and electronic equipment manufacturing. Hipot testers get […]
2×2 MIMO software helps measure IEEE802.11ac WLAN equipment in real-world settings
Anritsu Co. has come out with 2×2 MIMO Measurement Software MX886200A-010 that extends the measurement capability of its Wireless Connectivity Test Set MT8862A. With the software installed, the MT8862A is said to be the world’s first solution that supports output signal quality, transmit power, receiver sensitivity, and 2×2 MIMO measurements on IEEE802.11ac WLAN equipment under […]
VIDEO: Time Domain Display Items in the Tektronix MDO3000 Series Oscilloscope
Time domain items are in the oscilloscope display are listed with explanations. Hi once more and welcome to our 90th Test and Measurement Video. Today’s topic is the Tektronix MDO3000 Series Oscilloscope, and items that appear in its time domain display. To illustrate, we accessed a ramp waveform from the arbitrary function generator and fed […]
Multi-gigabit LTE evaluation functions support LTE-Advanced Pro protocols
Two Gigabit LTE software options for the Anritsu Signalling Tester MD8430A support the increased communications speeds associated with LTE-Advanced Pro (LTE-A Pro). The LTE DL 6 Carrier Aggregation Option and LTE UL 256QAM Option extend the measurement capability of the MD8430A and provide engineers with a comprehensive test solution to accurately and efficiently evaluate LTE-A […]
