Special offer: PicoScope 2208

This is your last chance to buy the PicoScope 2208, a high-specification two-channel USB oscilloscope that offers amazing value for money. Use it for general-purpose debugging, troubleshooting and field servicing.

Although classified as an 'entry-level' model, the PicoScope 2208 is supplied with the full set of PicoScope functions including FFT spectrum analysis, color persistence display, math channels, serial decoding, automatic measurements with statistics, mask limit testing and advanced digital triggering. Dynamic performance specifications are also excellent for a scope in this price range: SFDR is better than 52 dB at 100 kHz and noise less than 180 µV RMS.

Here are just a few of the specifications and features:

  • Bandwidth: 200 MHz
  • Sampling rate: 1 GS/s max.
  • Timebases: 500 ps/div to 5000 s/div
  • Sensitivity: 10 mV/div to 4 V/div (10 divisions)
  • DC offset adjustment: full input range
  • Buffer memory: 100 MS up to 10 MS/s sampling rate; 40 kS above 10 MS/s
  • External 200 MHz trigger input

Programmers' Corner: Edge-counting in MATLAB®

We are constantly improving our support for PicoScope devices in MathWorks MATLAB.

We recently posted on our forum an explanation of how to count rising and falling edges of a signal acquired from a PicoScope using MathWorks MATLAB. This example is based on the Counting Complex Events Using Analog Input Data article by MathWorks and demonstrates how to count edges in a signal acquired from a PicoScope 2205A using the PicoScope 2000 Series MATLAB Instrument Driver. MATLAB v8.0 (2012b) with Instrument Control Toolbox v3.2 was used to create the example.

Tech Tips

PicoScope serial decoding "link files"

Did you know that you can customize PicoScope's built-in serial bus decoder to display data as text as well as numbers? This feature is invaluable if you are decoding a standard bus such as CAN, where the text 'Trunk open' is much easier to read than the default hex ID of '0x3B1' (actual values are application-dependent).

How It's Done: Look for the Link: label in the Serial Decoding window. To the right of this is a + button that saves a template file (.xls or .csv) containing the necessary structure. Edit this file, adding your own number–text pairs, and save it. You can now click the drop-down list labelled Link:, browse to the link file and open it. PicoScope will replace packet data values with the strings that you have provided.

Triggering on two channels in PicoScope

Q. I need to be able to trigger from either of two channels which will be used almost at random. Is there a way to trigger if either channel activates?

A. On newer scope models, the Advanced Triggers feature does what you need. Select a trigger mode such as Auto or Repeat and then click the Advanced Triggers button. In the Advanced Triggers list you will find a Logic option. You can then set up independent triggering conditions on each channel, and finally combine the active channels using a Boolean operator. In this case select the OR operator to trigger on whichever channel meets its condition first.
