One of the best ways to ensure a MOSFET is functioning properly and meets specifications is to determine its characteristics by tracing I-V curves. There are a number of output characteristics requiring I-V tests; you can derive gate leakage, breakdown voltage, threshold voltage, transfer characteristics, and drain current all by simply tracing I-V characteristics and verifying the device is working as it should.

Tektronix class leading High Performance Oscilloscopes are now available with enhanced capabilities and features included as standard. Tektronix DPO/ MSO 12.5GHZ – 33GHZ C, DX and SX models come with additional enhancements at no additional cost when purchasing a new instrument.

High speed digital signals exhibit RF behavior in real-world devices, which creates a need for RF or microwave components when routing these signals in test systems.

Controlling instruments remotely has become a part of nearly every engineer’s and researcher’s life, whether by working remotely or combining instruments into large test systems.

Throughout these posts, 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 rates, smaller subcarrier spacing, longer guard intervals and the introduction of the OFDMA modulation technique providing capacity improvements and latency reduction.

Given the explosive growth of the communications industry, a tremendous amount of testing is being performed on the various components that make up different communications systems.

Oscilloscopes measure the voltage of an electrical signal, which is then graphically represented by waveforms. However, an oscilloscope can be used to take measurements for a number of different applications – one of which is frequency. But how does an oscilloscope measure frequency, exactly? Well, there’s a straightforward answer, and then there’s a slightly more complicated answer.

Most consumer products include electronic circuits or components, and an oscilloscope is used throughout the product design process to test those components. But what is an oscilloscope? And what does an oscilloscope measure?

Switching circuits that include reactive elements need special care to avoid problems due to transient effects. The methods used to limit transient effects depend on whether the load is capacitive or inductive.

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

LitePoint, a leading provider of wireless test solutions, today announced that it will provide the first Ultra-Wideband (UWB) test platform validated by the FiRa™ Consortium for PHY Conformance as part of their FiRa Certified™ Program.

A signal generator is an analog or digital device that engineers use to create electronic signals when testing circuit designs. There are many different types of signal generators with diverse features and applications. Below are the most common types of signal generators and the unique capabilities of each.

Switching an ohmmeter to a device under test is common to a variety of applications, including measuring the insulation resistance of materials, continuity testing of cables and connectors, contact resistance measurements, and measuring the resistance of components such as resistors, thermistors, and potentiometers.

Testing Fibre Optic networks are unavoidable due to Industry standards and warranty requirements, but there are many other reasons why Fibre network performance should be tested and monitored.

Learn about the Fibre Test Solutions across the network lifecycle.

Learn all about fibretesting including testing fibre for optical loss and optical speed as well as fibre testing best practices and procedures.

When switching currents of 1μA or less, special techniques must be used to minimize interferences, such as offset currents, leakage currents, electrostatic interference, triboelectric currents, and electrochemical currents.
