Bandwidth is a principal specification when choosing an oscilloscope or related instrument. What it means in this context is a displayed signal’s maximum frequency above which the scope attenuates the amplitude of the signal it sees. Problem is, this isn’t the only definition of bandwidth. The concept has slightly different meanings (and consequences) depending on […]
Multifunctional 16-bit AWGs include synchronized digital pattern generation
The T3AWG2152 and T3AWG2152-D generators are multifunctional 150MHz arbitrary/sweep/function generators that combine multiple functions in a single instrument, including a two-channel function and arbitrary waveform generator with an eight-channel digital pattern generator (in the D version). These three different functionalities are based on an advanced Direct Digital Synthesis (DDS) technology which allows glitch-free on-the-fly changes […]
Protocol test system captures 200-Gb Ethernet PAM4 signaling
The SierraNet M648 Ethernet and Fibre Channel Protocol Test System carries the latest Net Protocol Suite software version 4.30. SierraNet M648 offers extensive and deep Ethernet protocol analysis, including InFusion traffic impairment tools for both NRZ and PAM4 signaling and is the only dedicated analysis tool in the market to offer complete test and network […]
Line impedance stabilization network helps measure power-line-conducted interference
The TekBox TBL5016-2 is a Line Impedance Stabilization Network for the measurement of line-conducted interference within the range of 9 kHz to 30 MHz, according to the CISPR 16-1-2 standard. It has been designed for testing single-phase, ac-powered equipment that requires power to a maximum of 240 V and 16 A. Conducted noise can be […]
Two-port USB-controlled, lab-grade VNA operates from 300 kHz to 8.5 GHz
The Pico Technology PicoVNA 108 extends to 8.5 GHz the operating frequency range of the same-footprint PicoVNA 106 6 GHz instrument released three years ago. The new PicoVNA 108 fulfills user demand for “faster, more frequency range, more port power and dynamic range, and more functionality.” In addition to the PicoVNA 108’s extended range from […]
Subtleties of math functions in digital storage oscilloscopes
One of the great innovations in modern oscilloscopes is the Math mode. Even in many inexpensive scopes, it generally takes three forms: Dual Waveform Math, FFT, and Advanced Math. Dual Waveform Math requires two waveforms displayed in separate channels to function, but aside from that, it is quite simple. You just run a couple BNC […]
Benchtop, single-channel signal sources include 3, 6, and 12-GHz models
The Tabor Lucid LSxxx1B Series Analog RF Signal Generators are benchtop, single-channel signal sources with 3, 6, and 12 GHz models available. Featuring high power, fast switching speed, superior signal integrity and purity, removable memory card for maximum security, all the necessary modulated signals for analog communication systems, the Lucid Series is designed to meet […]
Programmable ac sources provide low THD in 3U form factor
The 9830B Series programmable ac power sources provide high performance and low total harmonic distortion in a 3U form factor. Offering 2,000 VA or 3,000 VA models, the new 9832B and 9833B provide the ability to connect three instruments to create a three-phase ac power source using the convenient three-phase kit (TL983P-KIT) option. The adapters […]
PC-based VNA handles signals out to 8.5 GHz
The newly announced PicoVNA 108 comes in the same low-cost, small-footprint and portable format as the widely used PicoVNA106 6 GHz instrument. The PicoVNA 108 can see out further to 8.5 GHz and it can see down deeper to –124 dB. It provides new “save on trigger” synchronization for multiple measurements, for example, with changing […]
Optical transceiver test platform reduces test time, accurately measures PAM4 optical signals
The new 8 Series sampling platform is a disaggregated modular instrument series boasting parallel acquisition, with up to four channels per mainframe and the highest measurement accuracy for PAM4 optical signals on multiple inputs simultaneously. The 8 Series consists of the TSO820 Sampling Oscilloscope Mainframe, optical sampling modules, and TSOVu, a new software platform that […]
