The USB-LOGI-500 logic analyzer enables to display time dependent digital signals on a monitor. Data with a speed up to 500 MSamples/sec can be sampled on each 36 channels. Included is the software Logi+ to simplify measurements under Windows.

Multiple sample rates / time behavior by measuring lines

The selection of the sampling is done in steps of 2 or 2.5. A sampling rate of 100Hz is even possible. To facilitate the analysis of measurements, both mouse buttons are used to position the blue and the red measurement line. The above status bar shows the time difference between both lines.

Triggering

The trigger condition defines the moment to start the recording. The trigger condition may be set on the left side of the program. Each channel can be triggered on either a 0, 1 or a X (ignore). As trigger-slope, a rising slope, a falling slope or a rising and falling slope can be chosen.
Both set trigger conditions can be provided with numerous links (even among themselves). The result may be counted with a 16 bit counter. That way, it is e.g. possible to start the sampling after the thousendth trigger event.

Pretrigger

Do you want to know what happens before the trigger event?
With a pre-trigger adjustable to 1/8, 2/8, 3/8, 4/8, 5/8, 6/8 or 7/8 , the time range is selected, that is recorded ahead of the effective triggering.

Zooming and quick positioning inside the shown measurement

zooming in and zooming out is of course given. Using the menue, it is also possible to jump to the trigger spot or to one of the two measuring lines. That way, moving to the desired position is quickly done, even in highly magnified views.

Save, load, print ...

Further functions, such as saving, loading, exporting and printing, rounds the rich functionalities of the Logi+ software.
As the software is downloadable from our website, measurements may even be shared with third persons who did not buy the logic analyzer.
