Fluke Corp. has expanded the capabilities of its Condition Monitoring system to include thermal monitoring with the addition of the new Fluke® 3550 FC Thermal Imaging Sensor. Maintenance managers can now collect a more comprehensive variety of key-indicator data — thermal imaging, voltage, current, temperature, and power — on critical equipment to build a real-time […]
Test and Measurement Tips
Measuring oscillator jitter
In digital electronics, jitter is a particularly insidious form of noise, to be understood, measured and where possible mitigated. Jitter is short-term, generally considered less that one second, deviation from the design intent. It consists of timing fluctuation in periods or transitions within cycles. An eye diagram tells the whole story. While vertical closing of […]

Heat sinks, cables, and accessories for RF/microwave amps
Pasternack has released a new series of RF and microwave power amplifier accessories that includes heat sinks, heat sinks with cooling fans and power control cable assemblies. Heat sinks are devices that enhance heat dissipation from a hot surface and are ideal for thermal management of power amplifiers in test and measurement applications. A functioning power amplifier […]
Measuring active and passive filters
The usual rationale for a filter in electronic circuitry is to reject unwanted portions of a spectrum or at least reduce their amplitudes to acceptable levels without attenuating the desired frequency or range of frequencies. In some situations, active filters are needed to perform this function, and often they are less expensive than alternate solutions […]
LCR meter resolves inductance to 1 nH, capacitance to 0.01 pF
Since its release in 2013, LCR-Reader has become a popular test and debugging tool for electronics development. It was important that the tool was offered at half price than its predecessor Smart Tweezers by reducing functionality and simplifying the operation of the device. On the contrary, LCR-Reader MP (Multi Purpose) offers many new features covering […]
VIDEO: Power Measurements With Markers In The Tektronix RSA306B Spectrum Analyzer
A Tektronix RSA306B PC-based spectrum analyzer is connected to the output from a Tektronix RTSA V3 Demo Board in order to demonstrate power measurements in the frequency domain. Hi and welcome to our 71st Test and Measurement Video. Today we’ll continue our demonstration of the Tektronix RSA306B PC-based spectrum analyzer connected to the Tektronix RTSA […]
High voltage, high efficiency, 1500W single-channel programmable DC supplies
Saelig Company, Inc. has introduced the PSU-HV Series of single output programmable switching DC power supplies that can provide up to 15A current and cover a power range up to 1560W. These high efficiency, high power density 1U-height supplies include five models from 100V to 600V output. More than one unit can be combined for […]
Measuring Ebers-Moll model parameters in transistors
If transistor circuits are to be of any use or amenable to diagnostic procedures, we must be able to model them. Even the best electronic test equipment is useless if we don’t know what to look for in the circuits under investigation. Transistors characteristically have multiple modes of conduction. We can view these phenomena in […]
