Here are the test & measurement features that got the most interest from readers in 2017. Why the sky is blue: LiDAR puts a focus on measuring Raleigh scattering Rayleigh scattering measurements are more than just an academic exercise. Scattering effects, Rayleigh and otherwise, can impact the operation of light-based sensors such […]
Test and Measurement Tips
Advanced math in the MDO3000 series oscilloscope
Advanced math functions in a digital storage oscilloscope involve, among other things, combining active and reference waveforms. First, we’ll see how reference waveforms are established in the instrument memory, and then return to advanced math. Active waveforms correspond to electrical energy that is present at the channel inputs. Often, however, the user has reason to […]
Economical EMI tent enclosures for benchtop precompliance tests
The TekBox TBST120/60/60/2 Shielded Tent provides an economical RF/EMI-attenuated environment for a variety of bench-top “EMI quiet” applications. The TBST-120/60/60/2 is a compact shielded tent, designed to suppress interference from ambient noise during EMC pre-compliance measurements. With an outer dimension of 4x2x2 ft., it can accommodate pre-compliance test equipment such as LISNs or TEM-cells or […]
Basics of oscilloscope roll mode, act-on-event, and the trigger menu
Roll mode in a digital storage oscilloscope yields a display different from that of the usual time-based view. Viewing a low-frequency periodic signal, the trace moves from right to left along the Y-axis, resembling what you would see in an analog strip chart. The time base, rather than moving in response to triggering as in […]
200-MHz, two-channel scope carries economical price tag
The new DS2000E Series Oscilloscope, a 200 MHz, 2 channel scope is available at either 100 MHz or 200 MHz bandwidths. All models provide 2 analog channels with 50-Ω input impedance standard. With real-time sample rate of 1 GS/sec (on both channels), memory depth of up to 28 Mpts standard, and waveform capture rate up […]

The FieldFox to 89600 VSA link provides a powerful combination of hardware and software for design and troubleshooting of devices using signal formats, including: · APCO-25 and TETRA for public safety radio · IEEE 802.11p for wireless vehicular communications […]
Vector adapter lets signal generators produce realistic electronic warfare threat simulations
An agile vector adapter extends the capabilities of the UXG X-Series agile signal generators to generate complex pulsed signals and waveforms based on IQ data for more realistic electronic warfare threat simulations. The N5194A UXG X-Series agile vector adapter enables the industry’s highest fidelity agile threat simulations when used with Keysight’s commercial off-the-shelf (COTS), UXG […]
PC software for EMC pre-compliance testing
The TekBox EMCView Pre-compliance Testing Software is PC-compatible software simplifies the process of EMC pre-compliance testing of radiated and conducted emissions. EMCView complements an emissions test setup of a spectrum analyzer, an LISN (Line Impedance Stabilization Networks) and an EMI-quiet TEM (Transverse ElectroMagnetic) Cell. Built-in amplitude correction provides the correction and conversion coefficients for cables, […]
New radio test capabilities devised for 3GPP 5G wireless setups
What is billed as an industry first 5G NR ready device workflow solution is said to address the entire device R&D workflow and scales from sub-6 GHz to mmWave. The UXM 5G Wireless Test Platform, developed by Keysight Technologies, Inc., is said to help prototype and develop 5G chipsets and devices while keeping up with […]
Basics of math functions on oscilloscopes
Virtually every digital storage oscilloscope has math functionality. This goes beyond the instrument’s ability to measure, quantify and display the many waveform parameters of a signal at the input, although those properties are important too. If you push the Math button while the oscilloscope is operating in the time domain, you will instantly see these […]
