An oscilloscope, formerly known as an oscillograph, is a benchtop instrument that graphically displays electrical signals and shows how those signals change over time.

Learn important troubleshooting techniques for ESD compliance failures.

Applications for current switching include testing of power supplies, insulation resistance, capacitor leakage, resistivity of materials, batteries, and semiconductors.

Testing power and signal integrity using an oscilloscope-based solution has some inherent challenges that need to be considered and resolved for optimum performance. We’ll address five of those here, but first let’s take step back and define what we mean by power and signal integrity.

A benchtop DC power supply is a standard piece of test and measurement equipment used by electrical engineers and circuit designers to power and test their circuit system designs in the lab and in the field. But what exactly does it do and how can you find the right bench power supply for your application? We’ll cover all that and more.

Extensive research and development have been invested in semiconductor-based biosensors because of their low cost, rapid response, and accurate detection. In particular, field effect transistor-based biosensors, or bioFETs, are used in a wide variety of applications such as in biological research, point of care diagnostics, environmental applications, and even food safety.

VIAVI Solutions released updated Auto-Test Applications for the 3920 Series and the 8800 Series Radio Test Sets. The changes are listed in the Release Notes on the 3920 Series Software page and the 8800 Series Software page

When switching low voltage signals (millivolts or less), special techniques must be used to avoid unwanted voltage errors. However, the required accuracy will determine if these techniques are necessary.

Many different applications involve switching a voltmeter or voltage source to multiple devices, including testing batteries, electrochemical cells, circuit assemblies, thermocouples, etc.

Throughout this blog series, you’ll learn about the key RF-PHY changes made in Wi-Fi 6/802.11ax compared to Wi-Fi 5 and older generations: the addition of a new frequency band, higher modulation rate, smaller subcarrier spacing, longer guard interval and the introduction of the OFDMA modulation technique providing capacity improvements and latency reduction.

3Z Telecom (VIAVI) announce the availability of the latest version of firmware for the 3Z RF Vision Antenna Alignment Solution.

The RAN (Radio Access Network) architecture for mobile networks includes a remote radio unit (RRU) located at the top of a cell tower, which communicates with a baseband unit (BBU) at the base of the tower.

O-RAN was big news last year, and a recent announcement from the O-RAN Alliance – one of the main bodies encouraging open RAN innovation, highlights the importance of benchmarking and testing in helping operators and others develop and get value from Open RAN deployments.

Many electronic test systems use relay switching to connect multiple devices to sources and measurement instruments. In some cases, multiple sources and measuring instruments are connected to a single device.

Fibre optic cables are becoming more and more important in our daily lives. They are used to transmit large amounts of information in a short period, and we strongly rely on them to maintain a reliable network connection.

In the previous blog, LitePoint talked about some of the key concepts involved in 5G over-the-air (OTA) test and measurement decisions and how each of these elements is critical in ensuring accurate and reliable 5G OTA measurements.

LitePoint, a leading provider of wireless test solutions, today announced it has signed an agreement with Qualcomm Technologies, Inc.

The creation of the 800G ecosystem has begun. Alpha samples of 800G OSFP modules have been demonstrated and we will likely see alpha QSFP-DD800 in a few months.

Midband (or C-band) is considered the “waterfront property” of RF spectrum for 5G. It offers the best compromise between RF coverage and RF bandwidth.

This blog will cover some of the key concepts involved in 5G OTA test and measurement decisions. This will include the dimension of the active radiating antenna module, far field region, quiet zone, link budget calculations and OTA setup calibration.
