Test and Measurement Tips
Understanding basic oscilloscope uses
The dominant oscilloscope type today is digital. A relatively small number of analog oscilloscopes are still made for educational purposes and low-end DIY kits. The digital revolution in oscilloscope design, initiated by Walter LeCroy over 50 years ago, made possible vast new capabilities and features. Still, it is worthwhile for perspective to look back at […]
Budget-priced transistor testing
The field-effect transistor (FET) in one form or another has largely superseded the earlier bipolar junction transistor (BJT). Both can do amplification, oscillation, and switching, but the methods in getting there are quite different as are the input and output impedances. First, by way of background, we’ll look back at the BJT. It contains three […]
Sensor acquisition modules work with high-def scopes
A Sensor Acquisition Module (SAM40) works exclusively with the Teledyne LeCroy 12-bit HDO family of scopes. The SAM40 provides up to 24 input channels for low frequency (sensor signal) acquisition and analysis. It connects to a 4 or 8-channel Teledyne LeCroy 12-bit resolution high-definition oscilloscope (HD4096 HDOs and MDAs) to provide Analog+Digital+Sensor (up to 8+16+24 […]
Advanced new instrument enclosures now with bail arms
METCASE’s advanced new TECHNOMET instrument enclosures can now be ordered with bail arms for portable electronics applications. The bail arm is comfortable to hold and also doubles as a desk stand which can be indexed in 30o increments. The 5.90” high desktop models also feature recessed side handles as standard. Applications for TECHNOMET include medical […]
Measuring energy without getting fooled
James Prescott Joule, in formulating what is now known as Joule’s Law, found that various forms of energy such as mechanical, electrical and heat are essentially identical and can be changed one into the other. His work formed the theoretical basis for the First Law of Thermodynamics. Joule further investigated the phenomenon of magnetostriction. He […]

A Tektronix RSA306B PC-based spectrum analyzer is connected to the output from a Tektronix RTSA V3 Demo Board in order to demonstrate trace detection and function controls. Hi and welcome to our 72nd Test and Measurement Video. Today we are continuing our demonstration of the Tektronix RSA306B PC-based spectrum analyzer. This recent Tektronix offering makes […]
VIDEO: Save and Recall Functions In The Tektronix RSA306B Spectrum Analyzer
A Tektronix RSA306B PC-based spectrum analyzer demonstrates save and recall functions, using a PC’s interactive on-screen controls. Greetings once more and welcome to our 73rd Test and Measurement video. Today we are looking at the Save and Recall capabilities in the Tektronix RSA306B PC-based spectrum analyzer. By way of background, a brief discussion of spectrum […]
Narrowband-IoT over-the-air test setup works with reverberation test chambers
Keysight Technologies, Inc. today announced the collaboration with Bluetest on the successful creation of a narrowband – internet of things (NB-IoT)) over-the-air (OTA) solution for use in Bluetest Reverberation Test Systems (bluetest.se/products/chambers). The solution, used by one of Japan’s top operator customers, demonstrates the market leading position of both companies in NB-IoT test. “We are […]
Relay controlled programmable attenuators span dc to 2 GHz
Pasternack, a leading provider of RF, microwave and millimeter wave products, has released a new series of relay controlled programmable attenuators. Typical applications include signal conditioning and level control, matching impedances of sources and loads and measuring the gain or loss of two-port devices. Relay Controlled Programmable Attenuators offer accurate and stable performance with very low […]
