I recently found out that in addition to a software frequency measurement (shown in the bottom right) the DS1000Z series has a hardware frequency counter (shown in the top right). The hardware counter is enabled by pressing the “measure” button, select counter, CH1. The display shows 6 digits, or 1 ppm resolution, but I was unable to find a specified accuracy for the counter. My testing suggests the accuracy at ~25C ambient temperature is 1-2ppm.
1 GS/s 50 MHz 4-channel Digital Oscilloscope – Rigol DS1054Z: The ultimate debugging tool for electronics, this oscilloscope will turn you into a “Circuit Whisperer”. You will be able to peer into the workings of your circuits to better understand them. Difficult problems will suddenly become trivial. We tried many beginner oscilloscopes and found this one to be a perfect balance of price and function for anyone looking to to examine signals lower than 50MHz and in need of 4 channels. At this price, it’s perfect as a ‘first scope’ or as a hacker-space resource to share – and can be used for years as your projects get more complicated. Read more.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
