ARINC 429 defines the physical and electrical interfaces of a two-wire data bus and the data protocol to support an aircraft's avionics local area network. It employs several techniques, including twisted-pair wiring and balanced differential signaling, to minimize electromagnetic interference (EMI) with on-board radios and other equipment.
Using serial decoding in PicoScope 6.10 or later you can now decode ARINC 429 signals. Simply capture a waveform, click Tools > Serial Decoding, select the ARINC protocol and accept the default settings. In most cases these are enough to decode the signal. Output is shown in a graphical view with decoded data on the same axis as the analog signals, and a in tabular view with powerful search and filtering options.
You may have heard of PicoScope's math channels but are not sure that you need the powerful equations, filtering and scaling features. You might not know that in many cases you can bypass the advanced features and use just the built-in math channels. No setup is required: all you have to do is switch them on and use them. Enabling a built-in math channel is as simple as this:
That's all there is to it! The chosen math channel will appear in the scope view and behave just like any other scope trace: you can scale and offset it, make automated measurements, save it to a file or use it as a reference waveform.
The PicoScope 5000 Series Flexible Resolution Oscilloscopes give you a range of resolutions from 8 bits to 16 bits in hardware. With just one PicoScope on your workbench you can choose between 1 GS/s sampling at low resolution, ideal for troubleshooting digital logic, and 62 MS/s sampling at high resolution with over 70 dB SFDR for viewing low-noise, low-amplitude analog signals. There are several other resolution options in between. The oscilloscope's novel sampling architecture gives you better dynamic performance than the software-enhanced resolution available on many scopes.
Our YouTube video explains the benefits of flexible resolution, and demonstrates how the PicoScope 5000 Series can be used to view HF noise on a LF signal at varying resolutions.

PicoScope 6 has a comprehensive set of options for saving, applying and restoring startup settings to minimize the time you spend setting up the software. They are all under the File > Start-up Settings menu. Here are some of the things you can do with them:
Many more options are possible: experiment with the File > Start-up Settings menu or read the PicoScope 6 User's Guide.
You've undoubtedly found the zoom controls in the PicoScope 6 toolbar, but did you know that you can optionally zoom on the x (time) axis only? This is useful if you've changed the vertical scale and don't want to disturb your settings. There are in fact several ways to zoom on the x axis:
If you make a mistake, you can always use the Undo Zoom button to return to the previous view.
