The Research Module (EP25 and VEMP option)

Export waveforms

With the click of a mouse, you can select the recording you want to export in its averaged state, as presented on the screen. This will save an XML file on your hard drive. You can view the XML file in Microsoft® Excel, MATLAB® or similar analysis software.

The export waveform/session function is available on saved recordings that are created on an Eclipse with the Research Module license, even when viewed on another PC. This gives the ability to collect data in one location and analyze in another without the need for a connection to the Eclipse.

Import WAV files

The Research Module allows you to import WAV files (including speech stimuli), which you can use as stimuli in evoked potential testing.

• Add a customized speech sound.
• The speech stimuli, Da, Ba and Ga are also included.
• You can calibrate custom WAV file stimuli and specify a peRETSPL - nHL correction value, as with traditional stimuli.
• Combine two different WAV files to create an alternating polarity stimulus.
• You can specify a WAV file as a continuous stimulus and use it as masking noise.

Data logging

The data logging function allows you to save (log) all sweeps, meaning you can 'replay' the entire recording in analysis software such as Microsoft® Excel or MATLAB®. From here, you can modify many test parameters (e.g. change the filtering or apply weighted averaging in a replay of all the sweeps) and reassess the resulting waveform.

You can apply data logging to both custom research protocols and the standard default protocols. The logged sweeps are saved in three text files on the hard-drive.
