PicoScope 4224 & 4424
High resolution oscilloscopes
On many oscilloscopes waveform math just means simple calculations such as A + B. With a PicoScope it means much, much more.
With PicoScope 6 you can select simple functions such as addition and inversion, or open the equation editor to create complex functions involving filters (lowpass, highpass, bandpass and bandstop filters), trigonometry, exponentials, logarithms, statistics, integrals and derivatives.
Waveform math also allows you to plot live signals alongside historic peak, averaged or filtered waveforms.
You can also use math channels to reveal new details in complex signals. An example would be to graph the changing duty cycle or frequency of your signal over time.
The custom probes feature allows you to correct for gain, attenuation, offsets and nonlinearities in probes, sensors or transducers that you connect to the oscilloscope. This could be used to scale the output of a current probe so that it correctly displays amperes. A more advanced use would be to scale the output of a nonlinear temperature sensor using the table lookup function.
Definitions for standard Pico-supplied oscilloscope probes and current clamps are included. User-created probes may be saved for later use.
PicoScope can be programmed to execute actions when certain events occur.
The events that can trigger an alarm include mask limit fails, trigger events and buffers full.
The actions that PicoScope can execute include saving a file, playing a sound, or executing a program.
Alarms, coupled with mask limit testing, help to quickly validate signal quality in electronic system designs.
The software development kit (SDK) allows you to write your own software and includes drivers for Microsoft Windows and beta drivers for Apple Mac (OS X) and Linux (including Raspberry Pi and BeagleBone).
Example code shows how to interface to third-party software packages such as Microsoft Excel, National Instruments LabVIEW and MathWorks MATLAB.
The drivers support USB data streaming, a mode which captures gap-free continuous data over USB direct to the PC’s RAM or hard disk at rates of up to 20 MS/s. Capture size is limited only by available PC storage. Sampling rates in streaming mode are subject to PC specifications and application loading.
Your PicoScope is provided with many powerful tools to help you acquire and analyze waveforms. While these tools can be used on their own, the real power of PicoScope lies in the way they have been designed to work together.
As an example, the rapid trigger mode allows you to collect 10 000 waveforms in a few milliseconds with minimal dead time between them. Manually searching through these waveforms would be time-consuming, so just pick a waveform you are happy with and let the mask tools scan through for you. When done, the measurements will tell you how many have failed and the buffer navigator allows you to hide the good waveforms and just display the problem ones. This video shows you how.
Perhaps instead you want to plot changing duty cycle as a graph? How about outputting a waveform from the AWG and also automatically saving the waveform to disk when a trigger condition is met? With the power of PicoScope the possibilities are almost endless. To find out even more about the capabilities of PicoScope software, visit our A to Z of PC Oscilloscopes.
