UDP sender enables PoKeys device to send simple messages using UDP protocol on request from the PoBlocks project. PoKeys InterCom protocol on the other hand enables sending data between PoKeys devices. PoKeys (Simple) UDP sender As the name applies, UDP sender … Read more
A new version of the PoKeys plugin for Mach4 was released today. Most changes have been done ‘under the hood’, the biggest one affecting the MPG jogging with PoKeys devices. MPG jogging is a very useful feature of PoKeys57CNC devices that enables improved control over the CNC machine and resembles the handwheel of a manual … 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

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 refresh time … Read more
Oscilloscope probe compensation is a procedure to reduce impact of probes on measured signal. We will show that on our Mega50 USB oscilloscope from our measurement instruments. 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 … 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
