Introduction Minimum PC requirements To ensure that your PicoScope 5000 Series Oscilloscope operates correctly, you must have a computer with at least the minimum system requirements as shown in the following table. The performance of the oscilloscope will be better with a more powerful PC, and will benefit from a multi-core processor.
Access. The licensee agrees to allow access to this software only to persons who have been informed of and agree to abide by these conditions. Usage. The software in this release is for use only with Pico products or with data collected using Pico products.
Programming the 5000 Series oscilloscopes dynamic link library in your PicoScope installation directory allows ps5000a.dll you to program a PicoScope 5000 Series (A API) oscilloscope using standard C function calls. A typical program for capturing data consists of the following steps: Open the scope unit.
Triggering Triggering PicoScope 5000 Series oscilloscopes can either start collecting data immediately, or be programmed to wait for a trigger event to occur. In both cases you need to use the PicoScope 5000 trigger function which in turn calls ps5000aSetSimpleTrigger,...
PicoScope 5000 Series (A API) Programmer's Guide Sampling modes PicoScope 5000 Series oscilloscopes can run in various sampling modes. Block mode. In this mode, the scope stores data in its buffer memory and then transfers it to the PC. When the data has been collected it is possible to examine the data, with an optional downsampling factor.
Sampling modes Block mode In block mode, the computer prompts a PicoScope 5000 Series oscilloscope to collect a block of data into its internal memory. When the oscilloscope has collected the whole block, it signals that it is ready and then transfers the whole block to the computer's memory through the USB port.
In normal block mode, the PicoScope 5000 series scopes collect one waveform at a time. You start the the device running, wait until all samples are collected by the device, and then download the data to the PC or start another run. There is a time overhead of tens of milliseconds associated with starting a run, causing a gap between waveforms.
