New PicoScope 2-channel, 4-channel and mixed-signal models!

We've delayed this month's newsletter to bring you news of an exciting new range of oscilloscopes!

The brand new PicoScope 2000 Series low-cost, ultra-compact oscilloscopes give you better performance and more features than ever before – all in an extremely portable package. Now you can carry an oscilloscope, function generator, arbitrary waveform generator (AWG), spectrum analyzer, logic analyzer and serial protocol decoder with you wherever you go. PicoScope USB oscilloscopes run on practically any PC or laptop with Windows 7, 8 or 10.

These oscilloscopes may be small, but just look at the features that are included in the price:

  • Up to 100 MHz bandwidth
  • Up to 1 GS/s sampling on analog channels
  • Mixed signal (MSO) models with 16 digital channels
  • Up to 128 MS deep buffer memory
  • Decode up to 15 serial protocols
  • Up to 1 MHz function generator and AWG
  • Free software updates
  • Beta software for Linux and OS X
  • Free Software Development Kit (SDK)

There are 15 models to choose from in the new PicoScope 2000 Series with varying channel counts, bandwidths and buffer memory depths. Here is just a selection of the models available in the PicoScope 2000 Series:

Model Bandwidth Channels AWG? Price
PicoScope 2204A without probes 10 MHz 2 Yes $129 / €109 / £79
PicoScope 2206B 50 MHz 2 Yes $379 / €319 / £229
PicoScope 2408B 100 MHz 4 Yes $1235 / €1045 / £749
PicoScope 2205A MSO 25 MHz 2+16D Yes $489 / €419 / £299
PicoScope 2208B MSO 100 MHz 2+16D Yes $1075 / €909 / £649

New resource for programmers: PicoApps

Applications and example code for oscilloscopes and data loggers

PicoApps showcases third-party applications that add new functions to your oscilloscope or data logger. It also contains example code to help with writing your own applications. If you've written something that you'd like to share with everyone, please tell us about it. A big thank-you to those of you who have already submitted an app.

Items on PicoApps include:

  • Frequency Response Analyzer with Bode Plots
  • Java interface to the PicoScope 2000 Series API
  • National Instruments LabVIEW – power factor example
  • MathWorks MATLAB – using Signal Processing Toolbox features to analyze PicoScope data

Browse the PicoApps library. No registration required.

New PicoScope beta release

Be one of the first to try our new beta release, PicoScope 6.12.1. This includes a number of experimental features that will soon be appearing in our stable software, including:

  • Edge counting and pulse counting measurements (by popular request!)
  • Color-coded serial decoding packets
  • Easier touchscreen operation

PicoScope R6.12.1 Beta is available from the Downloads page

Video of the month: PicoScope software release 6.11.7

We're adding features to PicoScope all the time. Recent additions include new serial protocols; math functions for filtering, frequency and duty cycle; and improved support for touchscreens. Watch this video to see the new features in action.

Tech Tips: FFT amplitude, UART decoding

Q. I would like to know why the FFT of a 1 kHz sine wave of 2 V amplitude gives a peak at 1 kHz of only 1.3 V in PicoScope. The spectrum mode was set to linear amplitude and a Blackman window.

A. The amplitude in FFT is the root mean square (RMS) value of the waveform. The FFT settings, such as the number of bins, where the bins fall in relation to the signal frequency and the window function used, will also affect the results. A flat-top window is best for accurate measurement of amplitude. For a 2 V peak (4 V peak to peak) sine wave the RMS value is 1.414 V. This is close to your measured value of 1.3 V. The remaining error might be due to distortion in the signal, if some of the energy has been diverted from the fundamental into the harmonics.

​Q. I wonder if PicoScope 6 can decode RS-485 as it decodes RS-232....

A. Yes, it can. RS-232 and RS-485 both use the same UART communication and can be decoded in PicoScope 6. We recently renamed the decoder to "UART (RS-232, RS-422, RS-485)" to make this clearer. In fact you can decode any UART signal regardless of the electrical standard, including TTL and CMOS.
