We are deeply upset by the sad loss of Richard, who was a key member of the Pico family and worked in our North American office for 11 years. We will all miss his knowledge, enthusiasm, friendship and lively sense of humor. Our thoughts are with Richard's family and friends at this difficult time.
Elektor magazine has just published a detailed review of the PicoScope 2208B MSO (mixed-signal oscilloscope). Within hours of setting up his new oscilloscope, the author was able to pinpoint a fault in an audio amplifier.
Find out how easy it is to get started with your first PicoScope and why it's important to compensate your scope probes!
This recent video is an introduction to the latest PicoScope 2000 Series oscilloscopes. It shows how you can use them in oscilloscope mode, spectrum analyzer mode and (with the mixed-signal models) as logic analyzers too.
We recommend that all our Data Logger users download the latest update to benefit from recent bug fixes and improvements.
The PicoScope 2000 Series of ultra-compact oscilloscopes includes 2-channel, 4-channel and mixed-signal models (MSOs). This month we're focusing on the MSO models, which pack an amazing list of features into a tiny enclosure:
See the PicoScope 2000 Series video above, and visit our video library for independent reviews.
Q. Is there a way to graph PWM signal? I need to verify an 8 to 92% duty cycle signal. It is being generated at 500 Hz I believe. It is an engine throttle control signal for an ECU. A graph is ideal to show no fluctuations in the PWM output.
A. Yes there is. Go to Tools > Math Channels, click Create, then click Advanced, and you will see a duty button. Click that and then the button for the input channel (such as A). That will create a graph of duty cycle.
You can also use PicoScope's Math Channels to graph frequency, peak values and a wide range of other mathematical functions.
Q. I've watched your YouTube video on "How to use an oscilloscope to measure the output level and gain of an audio amplifier". Now could you advise me on choosing the right oscilloscope for the job?
A. High bandwidth is not necessary for audio work. We recommend at least 12-bit resolution, ideally 16-bit, to show up faults such as distortion. Finally you need to ensure that the oscilloscope's input range is large enough for the voltage to be measured, taking into account the attenuation of the probes that you intend to use. For 16-bit work the PicoScope 4262 is ideal. For less demanding 12-bit applications the PicoScope 4224 or 4424 would be suitable.
