File Import and Export

The collected frame of data can be saved as a wave file (*.wav) or exported as a text file (*.txt). All analysis results can be exported as text files (*.txt). All graphs can be exported as bitmap files (*.bmp) or printed out directly. A long wave file can be imported frame by frame either manually or automatically.

Wave files with PCM format or properly formatted text file can be imported for analysis. The signal generated by the Signal Generator can be saved as a wave file (*.wav) or a text file (*.txt) for a given duration of up to 1000 seconds as long as the spare space on the hard disk is sufficient. The saved files can be in turn imported for display and analysis or used by other software.

Data Merging and Extraction

Combining data from individual channels of different wave files and extracting part of data from a wave file are supported.

Save and Load Pannel Setting

You can save your preferred instrument panel setting either as default or as a customized panel setting for later use.

Controls/Options Enabling and Disabling

Graphical User Interface items such as menu items, button, combo box, edit box, radio box, check box are enabled/disabled based on context, so as to void any mis-understanding and mis-operation.

Multilingual User Interface

The software supports Multilingual User Interface under Windows 2000, XP, 2003, Vista and above. Currently supported languages are English, French, German, Italian, Portuguese, Spanish, Russian, Simplified Chinese, Traditional Chinese, Japanese and Korean. It supports only the local language and English under Window 95, 98, Me and Windows NT.
