TMC introduces SEM-Base® VI, the next generation of its STACIS® active piezoelectric vibration cancellation product line. Like the original SEM-Base system, SEM-Base VI is designed to support all commercial scanning electron microscopes (SEMs). It features improved vibration isolation performance and a faster and more-robust controller that provides the user with an advanced graphical user interface […]
Test and Measurement Tips
Single instrument handles LTE-Advanced 1 Gbps IP throughput testing
Anritsu Company introduces a single-instrument solution that enables 1 Gbps IP data communications throughput testing based on its Signalling Tester MD8475B that supports 4×4 MIMO with 256QAM high-order modulation and four component carrier aggregation. The integrated system, which consists of the new Enhanced Multi-signalling Unit MD8475B-071 option and LTE 4×4 MIMO software, lowers cost-of-test and improves time-to-market by […]
Isolated 4-channel 200 MHz scope handles up to 1 kV swings
Saelig Company Inc. has introduced the Cleverscope CS448, a unique isolated high common-mode rejection ratio (CMRR) four-channel 200MHz 14-bit oscilloscope. It has been designed to measure high voltage, fast slew-rate signals such as those in a full or three-phase power electronic switching bridge (e.g. gate drives to measure voltage and charge, power switching to measure loss and […]
Power supplies feature output noise levels below 4 mV p-p
Originally developed as a custom solution for highly sensitive electronic measuring equipment designed to capture experimental ring accelerator data, the new Eplax 3U 7HP 19″ pluggable PSU with output noise levels below 4 mV p-p is now available as a standard product through Verotec Inc. for any high sensitivity application where ripples and spikes on […]
Multifunction test instruments connect to PCs via USB/Wi-Fi
Digilent Inc.’s OpenScope: Open-source PICMZ All-in-One Instrumentation Device is available for immediate shipment worldwide from Digi-Key Electronics, a global electronic components distributor, the companies announced today. The OpenScope MZ is a portable multi-function programmable instrumentation module. What does that mean? It is a device that connects to a computer (through Wi-Fi or a USB cable) that allows […]
VIDEO: Tektronix RSA306B PC-Based Spectrum Analyzer
A new Tektronix PC-based spectrum analyzer is described and configured to a Windows laptop computer, and its use is demonstrated. Hi and welcome to our 68th Test and Measurement video. Today we’ll do an overview of the Tektronix amazing breakthrough RSA306B PC-based spectrum analyzer. To generalize, the spectrum analyzer is similar to the oscilloscope, but […]
Dealing with and displaying power-line harmonics
Harmonics are waveforms that may accompany a periodic fundamental (also known as the first harmonic) in a divergent infinite series. When they arise, their frequencies are integer multiples of the fundamental. If this fundamental is 60 Hz, the second harmonic is 120 Hz, the third harmonic is 180 Hz, the fourth harmonic is 240 Hz […]
Testing operational amplifiers
Because it is able to function in so many diverse ways, the op-amp can be the defining element in electronic circuits of any complexity. Applications go far beyond amplification. Because they are near-perfect dc amplifiers, op-amps are suitable for filtering, signal conditioning, and for performing such mathematical operations as addition, subtraction, differentiation, and integration. Op […]
The modern economics of renting test instruments
The development of online instrument exchanges puts a new wrinkle into how to get the optimum use of test gear. LEE TESCHLER EXECUTIVE EDITOR When a project comes up that involves expensive test gear like gigahertz-range signal analysis, statistics from the Equipment Leasing & Finance Foundation show this kind of instrumentation is increasingly acquired through […]
