A USB Scope For Linux Users

Pico Technology has reportedly restored the numbers of Linux users, by offering a software that will run under their preferred OS. The USB oscilloscopes are famous but its demand supply is majority wise restricted to Windows platforms.

The PicoScope 6 will now convert a Linux PC into an oscilloscope, FFT spectrum analyser and measuring device. The On-device buffering, which uses deep memory on some devices, enables the display to be updated frequently and smoothly, even for long time-bases.

It is to be noted that the most important features from PicoScope, for Windows, are include in PicoScope 6, like the scope, spectrum and persistence modes, interactive zoom, simple, delayed and advanced triggers, automatic measurements, and signal generator control.

The oscilloscope software is available for the Debian 7.0, which is code named as wheezy, Ubuntu 12.xx / 13.xx, as well as other Debian-based distributions with mono-runtime version 2.10.81. or higher. The drivers are available for the current scopes from the PicoScope 2000 to 6000 series.

The PicoScope software involves an USB oscilloscope from the PicoScope range. These oscilloscopes are available with the bandwidths of up to 1 GHz, up to 4 input channels, with hardware vertical resolutions up to 16 bits, sampling rates up to 5 GS/s, buffer sizes up to 2 GS, and built-in signal generators.

Some more features that are available on some models are flexible hardware resolution, switchable bandwidth limiters, switchable high-impedance and 50 ohm inputs, and differential inputs. The company has asserted that more functions will be added soon. For now, the users can save the captures for off-line analysis, share them with the other PicoScope for Windows and also with PicoScope for Linux users. They can export them in text, CSV and Mathworks MATLAB 4 formats.

Here Are 6 Things That Cinnamon Can Learn From KDE...

There's no age and time to start learning, you practically learn all your life. The same set of rules are followed by the tech world as well. KDE and Cinnamon are undoubtedly the two leading desktop environments in the Linux world today. The two are 'tough' competitors when it comes to functionality and user share. Cinnamon offers a pretty neat development speed, is widely acknowledged within the user community and provides noticeable chunks of control and simplicity. However, does it outsmart KDE? Well, not really!

Here are 6 things that Cinnamon can learn from KDE:

1. Cross-platform support

-Cinnamon is a Linux only desktop environment, on the other hand KDE is a truly cross-platform solution (its framework available on Solaris, FreeBSD, OSX, and even Windows).

-Now, Cinnamon will keep you happily busy as long as you have some form of Linux under the hood, however, with KDE users can test and explore its various options, tools and programs before thinking about switching fully!

2. Attention to detail

-Being a German idea, KDE is pretty neat (as tidy as 'tidy' could be!) and boasts of a very careful attention to detail. With KDE, everything seems to fit everything else.

-Whatever distribution it might be, if it runs KDE, you know you will have a solid, familiar behavior and an expected level of precision.

3. Full stack

-KDE desktop is a complete stack, no matter how deeply you search through the menus and options, the uniformity persists.

-You can search for additional content and supplemental software without leaving the comfort of your desktop environment.

4. Applications

-KDE comes with the most complete and most uniform set of applications that users could ever imagine, non-Linux operating systems included.

-On the other hand, with Cinnamon the system menu choice reflects the particular distro developers bundling their favorite set. Move from one Cinnamon to another and you will know!

5. Powerful services and social integration

-KDE programs are acclaimed for their highly detailed menus and options. Whatever application it might be, it comes with a set of extras and easy social integration.

6. Professional touch

-A powerful set of applications and a complete stack of tools and options bundled together with an extremely consistent behavior make KDE the most professional of all Linux desktop environments.

-Furthermore, thanks to Qt one day we may see more and more of this framework on non-desktop computing devices.
