Download Oscillogram Files
To view the oscillogram load its files in *.CFG and *.DAT format by pressing the “Select Files” button. The file names must be the same before the extension. After successfully loading the oscillogram files, you need to click the “Display” button, after which the signals will be displayed.
Display Signals from Oscillogram Files
The oscillogram viewer displays all the analog (Fig. 1) and discrete signals (Fig. 2) from the oscillogram files. For the oscillogram scaling and viewing values at a specific point is available. To do this, hover over the appropriate graph. You can use the left mouse button to scale the waveform. To restore the waveform to its original state, you must click the “Reset axes” button, available on the toolbar at the top of the waveform.

Signal value display
In order to determine the actual value of the signal at a certain point in time, you must move the mouse cursor to the desired point and press the left mouse button. After that, a vertical line will be displayed on the screen, and measurements of analog and discrete signals will appear on the left. For analog signals, the complex effective value is determined, which is determined using the Fourier filter on an interval of one period of the network frequency (Fig. 3). For discrete signals, the instantaneous value is displayed (Fig. 4).

Users have access to a toolbar that allows you to change the display of analog values to primary (button ) and secondary (button ), and also allows you to leave the display only of changing discrete signals (button ).

The buttons in the active position are highlighted.
The ability to display analog values in secondary quantities is available only for oscillograms in the COMTRADE 1999 format.
Currently, the oscillogram viewer supports oscillogram recorded in the COMTRADE 1991, COMTRADE 1999 format (BINARY and ASCII).
If the viewer does not open your oscillogram files, please inform us by e-mail email@example.com with attaching the oscillogram files, and we ary try to help you.
