October 31, 2014 In this podcast Steve Sandler of Picotest talks to Alix Paultre of Power Systems Design on the issues of power test,...
Techniques for accurate PSRR measurements
By John Rice, System Engineer, Texas Instruments and Steve Sandler, Managing Director, Picotest Introduction In theory, measuring the...
Match impedances when making measurements
Recently, I used a shielded coaxial cable to measure power supply ripple and the results were even noisier than using an oscilloscope...
Inside the 21st Century Power Test Lab
In this 5-minute video, Steve Sandler of AEi Systems (www.aeng.com) and Picotest (www.picotest.com) takes you on a tour of an advanced...
FAQ #23 What Injectors do I need for PDN Measurements?
Our J2112A current injector has been the most requested product to date. It provides a very fast low current pulse, though based on a RF...
How to Make Higher Voltage Power-Distribution-Network Measurements
Assuming the AC signals in the measurement are very small, the power ratings of the ports limit the absolute maximum DC voltage that can...
Clock Power Optimization Depends On Jitter Control
Clock-jitter performance has become a top priority among clock, analog-to-digital controller (ADC), and power-supply manufacturers. Why?...
Making Ripple Measurements
Making ripple measurements has traditionally been using an oscilloscope. For a number of technical reasons, an oscilloscope, in general,...
Use A Signal Analyzer To Measure Power Supply, Regulator, and Reference Noise
Oscilloscopes often are used to measure power supply, linear regulator, and reference noise. Since an oscilloscope has a sensitivity in...
Effectively Using the EM-6992 Near Field Probe Kit to Troubleshoot EMI Issues
The EM-6992 Probe Kit includes three magnetic (H) field and two electric (E) field passive, near-field probes and an extension handle...
Troubleshooting EMI: Use Versatile Instrument And Preamp To Search For Embedded Noise
Most engineers do not have convenient access to the equipment necessary for electromagnetic compliance (EMC) or electromagnetic...
Measuring Optocouplers with the J2130 DC Bias Injector and the OMICRON Lab Bode 100 VNA
In this measurement the J2130A provides a DC bias to the Optocoupler LED, which returns to ground through a termination resistor. The...
