User Interface

The included software allows complete control of the device from a PC and contains standard features expected in modern digital storage oscilloscopes (DSO) such as hold acquisition process, hold-off, zoom. In addition the software offers saving/loading of waveforms for future use, export to clipboard, printing of results and scope settings.
In order to keep the device functions up to date, the latest version of the software is always available on our website free of charge and runs in demonstration mode if no device is connected to the PC.

Main Screen

All basic oscilloscope controls are easily accessible directly from the main window making measurement similar to that of a stand-alone device.

Most parameters can be set by dragging items on the main screen such as vertical shift by dragging waveform or after trigger amount by dragging trigger mark. Other controls such as timebase up/down can be controlled by configurable hotkey. You can use two horizontal and two vertical cursors to perform any measurements on the waveform.

Waveform Analysis

The software can automatically calculate 19 waveform parameters and the fourier transformation can be used for analysis of the frequency domain.

Software automatically determines the waveform period and transforms just one period of the waveform. Alternatively, if manual mode is activated, you can select the data to be transformed. You can use inverse fourier transformation to simulate the waveform transition through a simple filter. The XY mode (Lissajous figures) is also included.

Export

The software offers several export options:

  • Internal Dataman format which can be opened in the software for comparison with measured data
  • ASCII file with options to configure format
  • Image with options to customise appearance and format


Measured data and protocol can be printed with options available to customise the layout.

Two optional software packages are available: 770 Development kit, which allows you to write your own application using the device and the 770 Roll mode, which turns the oscilloscope into a data logger.
