Sebastian voided his warranty and bravely went where others fear to tread, dissecting the Teledyne LeCroy HDO4024 12-Bit oscilloscope. He produced this post detailing his findings. Via the contact form.
Tomeko has posted an article describing miniscope v2d integrated arbitrary waveform generator: Cheap low-speed dual channel PC/USB oscilloscope and arbitrary waveform generator with STM32F3 microcontroller. Miniscope v2d is based on STM32F303CBT6 microcontroller – LQFP48 device from STM32F3 family featuring: 32 kB … Read more
Simple circuit to turn your oscilloscope into a TDR: This simple circuit allows you to use your oscilloscope as a Time Domain Reflectometer (TDR). This is how it works. Send a pulse down a cable and watch for the reflection. … Read more
Paulo Oliveira was experimenting with probing high speed signals with his oscilloscope. You might think that a 500 MHz probe would be adequate to probe a 125 MHz clock signal, but he demonstrates why this is not the case. He … Read more
