Teledyne LeCroy was discussing how high sample rates and bandwidth are important to accurately characterize pulse shapes created with an ESD generator. Their software package offers specialized parameters with adjustable levels that allow engineers to customize the necessary rise time, fall time, and width measurements to ensure that the generator meets industry standards. Built-in statistics and histicons provide the ability to quickly view a large number of measurements at a single glance. For Electrical Fast Transient (EFT), the fast rise times of EFT pulses along with the repetition rates of EFT bursts, require an oscilloscope with both high sample rate and long memory to accurately capture the waveforms. Long memory along with sequence acquisition mode enables the capture of many EFT bursts in a short period of time. Specialized rise, fall, and width pulse parameters, added with the software package and combined with statistics and histicons, allow for fast pulse measurements over all bursts. Built-in zoom capabilities allow you to quickly locate and view any pulses that may fall out of spec.
VDI is the opposite of most other companies as they have been offering products operating in the terahertz range for many years so are often asked to come down in frequency so are offering products in the higher microwave/lower mmWave range now. VDI now offers compact converters for frequency up and down-conversion. These converters are easy to use and well suited for high performance up and down conversion of wideband modulated signals. These modules are available from WR-28 (22.5-40 GHz) up to WR-10 (75-110 GHz), with additional bands in development. VDI has collaborated with Keysight to provide a turn-key solution for very wide bandwidth communication applications. Using VDI's compact converter product line, Keysight was able to generate and analyze up to 5 GHz of occupied bandwidth.
