The latest release of PoScope4 offers many new functions and improvements 

Device displays

Snap to grid

The Snap to grid lets you automatically tile the displays in the working area in different configuration. First number is Row and second is Column. When Snap to grid checked all displays will be positioned in a grid of size Row by Cols.

If none of the above is appropriate for your use, you can always tile the displays by yourself as you wish. The location and size of the displays in the working area are fully customizable. Displays tab also shows device functions.

Whenever displays needs to be aligned to the grid just check Snap to grid checkbox in top left corner and all displays will get aligned.

Even when Dynamic layout is used Snap to grid can position displays in a grid on any monitor.

Cross cursor

All analog displays (Oscilloscope, FFT, X/Y, Recorder) has been upgraded with Cross cursor feature. Cross cursor is following your mouse moves and instantaneously displaying signal properties at hovering point.

Logic analyzer doesn’t use cross cursor but more sophisticated analyze tool which shows digital signal related signal informations.

Storing display and device settings

All settings, including displays, devices are now stored into default Desktop file on PoScope4 exit. Additionaly we store all positions of GUI controls and recall them back on PoScope4 startup. Loading last saved settings enable users to work faster and more efficiently and not loosing your time repositioning GUI controls.

Freeze button

All displays are equipped with Freeze button which stops repaint of the display. It’s very useful for fast access to measured data without switching to Analyze mode.

PoScopeMega1 logic analyzer

Improved sampling frequency which goes now up to 4MHz (buffer mode)

Logic analyzer sampling frequency goes up to 4MHz

Logic analyzer

Every channel can be switched off/on simply by selecting it with mouse and keyboard combinations similar when selecting files in Explorer (in Windows OS). Click on Port A.6 and hold CTRL then click on Port A.7. Both channels are now selected. Now click on channel settings icon (any). Popup menu will show you options what can you do with channels. You can show all channels if any are hidden. You can also hide one of selected channels by clicking Hide this channel or you can hide all other unselected channels. In our case we click Hide unselected channels. After click Port A.6 and Port A.7 channels will be resized to take maximum of the window and all other channels will be hidden.

Support for new devices

PoScopeMega50

PoScope Mega50 is low power USB oscilloscope, function generator and logic analyzer all-in-one.  It’s especially convenient for outdoor measurements in remote places where power supply is limited and portability is very important. Integrated high quality analog to digital converters are able to sample up to 48MHz and with maximum data resolution of 8-bits. Function generator is capable of generating different pattern test signals with frequency up to 12,5kHz and maximum amplitude of 1,8Vpp. Logic analyzer captures up to 16 digital inputs and gathers data for further analysis. Included free software PoScope4 extends its usability for many different applications. Mega50 is a really powerful small size device that will save your time, money and make your work with measurements much easier.

PoRef216U-50V

PoRef216U-50V is precise DC voltage generator  with different voltage ranges. It offers two channel and can generate DC voltage up to 50V per channel or up to approx. 100V in special single channel mode. It’s connected and powered via USB and don’t wory the outputs are galvanicaly isolated from input circuit. PoRef216U-50V inteligence is based around excellent PoKeys controller.
