TDR Measurement Using LeCroy SPARQ

May 24, 2013 by Rolf Ostergaard

In this quick video I will show how to do a simple impedance test trace TDR measurement on a PCB using a homemade probe and the LeCroy SPARQ. This nice piece of equipment can do all kinds of fancy stuff including de-embedding of cables (which I used here) and gating away the effects of probes… Read more

Cheap Cool Logic Analyzer

February 25, 2013 by Rolf Ostergaard

The days of logic analyzers are not quite over yet. But due to signaling speeds going up, LA’s tend to be used a lot less these days. The issues are a combination of physical probing and speed. Traditional LA clip-on probes have very few places to attach on a modern high speed board with BGA’s… Read more

Cheap 5GHz SMA Calibration Kit

January 3, 2013 by Rolf Ostergaard

How to buy a cheap calibration kit. When using a VNA or network analyzer, you will need a “cal kit” (calibration kit) to calibrate away any effects of cables, connectors, etc. that are not part of what you are trying to measure. For some odd reason, official calibration kits are fairly expensive. But the guys… Read more

Cheap RLC Smart Tweezers on eBay

October 15, 2012 by Rolf Ostergaard

I just found some neat and quite cheap RLC smart tweezers on eBay. Having an RLC meter is really useful in many situations. For measuring the capacitance of all capacitors on a PCB at once or just an individual capacitor. Just to mention a few uses. Maybe you were aware, but I was surprised to… Read more
