Our most popular range of high–speed scopes, the PicoScope 3000 Series, has just been extended with six new 4–channel models. These USB–powered scopes have everything you need for everyday test and measurement: bandwidths up to 200 MHz, external trigger input, signal generator or AWG output, and an optional DC input to save your laptop battery.
If you own the PicoScope 2205 Mixed–Signal Oscilloscope (MSO) or are thinking of buying one, you should benefit from our latest new training videos. Industry expert Pete Darby explains how to use the scope and the software to best advantage.
The PicoScope 2205 MSO packs a 2–channel 100 MHz oscilloscope and 16–channel logic analyzer into a compact, portable case.
If you’re a PicoScope beginner then there are some features you might not have discovered yet. Here are three of the most useful.
1. Scaling feature for all types of probes. PicoScope has a number of built–in probe types, such as 10:1, and also allows you to define new ones. Click the channel button (labelled “A”, “B”, “C” or “D”) on the toolbar, then the “Probe“ menu at the top, then the required probe in the list. For example, if you selected “x10”, that channel is now set up to use a 10:1 probe.
2. Movable center line on y–axis for unipolar signals. Each PicoScope channel can be moved up and down by dragging its y–axis (the column of numbers to the left or right of the screen). If your signal is unipolar (for example, in the range 0 V to 1 V), you can drag the center line to the bottom. Adjusting the vertical scale to 2x will then allow you to make full use of the window.
3. Each signal displayed in a separate row. In PicoScope, each channel has its own y–axis. By default, these all occupy the full height of the display so signals often overlap. To separate them, right–click on the display and choose “Auto–arrange axes”. PicoScope will then move and resize all the channels so that they do not overlap.

“The Raspberry Pi and DrDAQ each pack a lot into a small package and seem like natural companions.”
Soon after the release last month of our Raspberry Pi driver for the DrDAQ Data Logger, Andrew Back wrote about his experience with the driver on the DesignSpark blog. Perhaps you can follow in his footsteps and create your own application for the DrDAQ.
Where did rapid triggering mode go?
Q. I would like to use rapid triggering mode with my PicoScope 3204A to avoid gaps between waveforms, but although it is listed as possible in the data sheet, it isn’t offered in the PicoScope trigger menu.
A. Rapid triggering mode is available only on the shorter timebases. Select a timebase of 1 ms/div or shorter and, if the scope supports it, the Rapid option will appear in the trigger menu.
PicoScope 3000 Series sampling rate
Q. Do the PicoScope 3000 Series scopes sample at 500 MS/s under all conditions, or can I reduce the sampling rate? Specifically, 8 MS storage is plenty for me if I can sample at 30 MS/s (but not at 500 MS/s). It’s not clear to me that this flexibility exists however.
A. The PicoScope software automatically adjusts the sampling rate depending on the timebase to make best use of your scope’s memory. You can check the sampling rate in the Properties panel, available under the Views menu. Similarly, with the software development kit (SDK), it is possible to set the desired sampling interval and number of samples to capture.
