The script demonstrates the use of MATLAB’s Instrument Control Toolbox to communicate with a Tektronix MSO64B oscilloscope via TCP/IP. It captures, scales, and plots data, measures signal properties, and optionally saves the results. … Continue reading >MATLAB Script for Tektronix Scope Plot and Measure
I created a photo montage below showing how to use a mixed signal oscilloscope as a logic analyzer. First, I establish a UART bus by connecting the analog probes to the Rx/Tx pins on the Uno board. This setup allows me to monitor the data transfer between the board and the IDE. Then, I use…
I am taking Andre’s “Crash Course Arduino and Microcontroller Development” on Udemy. As a seasoned embedded developer taking this course, I get to commit more details to memory—looking up less—for my own designs. I also use my full lab to enhance the projects during the course. Note the floppy disk connectors used to hook my meters…
Introduction Bell Telephone Laboratories (BTL) had an important realization: the transistor’s development would move a lot more quickly if they opened up the field to other companies. So in cooperation with the military services, BTL held the first symposium on Transistor electronics at the Murray Hill Laboratories in New Jersey, where the transistor was invented…
BiophysicsLab.com has added Arduino to its workbench for research and client support. The Circuit The Arduino Uno and a BME680 sensor board can be used to collect accurate temperature, humidity, pressure, and an indication of volatile organic compounds (VOC) in the air expressed as a changing resistance measure. In this project: An Arduino sketch displays…
This interactive MATLAB GUI application allows the user to quickly generate curves for 8 combinations of RC and RL circuits. Then, reuse the results to generate similar waveforms in popular signal generators and spreadsheets.
I present a detailed test methodology for 14 different BJT transistors along with lessons learning.
I present several resistor types all with the same value of 100kΩ. Each resistor is tested for stability over time and temperature.
How to Measure Transistor hFE
In this post I present a 2-byte data capture script using MATLAB along with the Instrument Control Toolbox.
