Isolated measurement Sometimes we would like to measure a signal with oscilloscope on a device, we are not familiar to. The reason might be that we don’t have a datasheet or a scheme available, or simply a common ground potential is not physically accessible. In such cases isolated USB oscilloscope can help. What’s more, I … Read more

The organizers would like to thank all the participants that they devoted the last few months to preparations for the competition, which they also attended. Special thanks also … Read more
Ground loop is a result of electricity flowing to a ground over two or more paths. Ground loop is usually generated by connecting together different power sources. Users in many cases believe that all ground points are at the same potential. That is far from the truth. All wires or other conductors have a resistance … Read more
The latest release of PoScope4 introduces new features and improvements PWM protocol decoder We’re introducing new PWM protocol decoder which helps with debugging of PWM signals. Improvements Improvement of export routines to speed up export to CSV and PCM formats for all displays. Added Autoscale buttons for each channel of Mega1 and Mega50 on control GUI … Read more
The latest release of PoScope4 introduces new features and improvements 1-wire protocol decoder We’re introducing new 1-wire protocol decoder including 1-wire sensor decoder for most popular 1-wire sensors. Bug fixes Cross cursor was displaying wrong time notation when used in analyze mode or in player mode in recorder display. Moving overview display didn’t … Read more
Oscilloscope probe compensation is a procedure to reduce impact of probes on measured signal. We have to keep in mind that oscilloscope probes aren’t just pieces of wire with pointy end attached to them. Here are two important aspects to consider when selecting and using probe: Faithfully transmit the signal from your device under test to the … Read more
The latest release of PoScope4 introduces improvements 1. Improved timebase. In previous versions timebase calculation was based upon samples displayed and multiplication factor which resulted in strange and sometimes useless timebase values. Now we improved data alignment in a way that timebase values always coresponds to 1, 2, 5 (per div) values pattern. For example: 1ns/div, … Read more
The latest release of PoScope4 introduces new features and performance improvements Axes alignment – Stacked mode Switching between two different axes alignment modes. Axes are by default aligned to left and right sides of display – parallel. New alignment option is called Stacked. All axes are aligned to the left side of chart and positioned each … Read more
[fusion_text]PoLabs is launching PoScopeMega50 usb oscilloscope, the smallest and lowest power consumption 48MS/s USB oscilloscope, function generator and logic analyzer in one on the market. It draws only 150mA thus the best choice for measurement environments which demands power autonomy and longevity. It’s especially convenient for outdoor measurements in remote places where power supply is … Read more
USB oscilloscope key performance properties In previous post we exposed key performance properties to consider when choosing USB oscilloscope. Let’s have a look at our two USB oscilloscopes and let’s compare them side by side. PoScope Mega1 PoScope Mega1 is lowest power consumption USB oscilloscope, function generator and logic analyzer in one on the market. It draws only … Read more
