Storing OSCOR™ Demodulated Signals


Tech Note imageTo assist with report writing and analysis after a sweep is complete, the OSCOR provides the ability  to capture various types of information from the display, demodulated video, and audio signals. All information captured is stored to either a compact flash card or a USB storage device, not the OSCOR itself. In order to recognize an external USB hard drive, the device must be formatted with a FAT file system such as FAT32. If needed, the OSCOR can format the hard drive using the Storage Manager feature (see page 22 of the OSCOR Green manual).


Screenshots
Screenshots are a quick way of capturing everything on the OSCOR display and can be taken at any point. To take a screenshot, press and release the SHIFT key followed by the HELP key. A dialog box will appear allowing users to select the location, file type, and file name before saving. Screenshots can be saved as .png or .bmp files.

Audio
There are two options available to record audio captured using the OSCOR. The Quick Record feature allows a user to easily record up to 30 seconds of audio that starts immediately when selected without having to adjust the recording properties first. After 30 seconds or when the user manually stops the recording, a dialog box appears allowing the user to specify the location and file type before saving.

To record a longer duration of audio, it is necessary to use the Record Audio feature, which requires users to setup the file location and type before the recording will begin. The OSCOR will continue recording audio to a file until it is either manually halted by the user, or when the storage device becomes full.

Demodulated Video
The OSCOR can capture screen shots of demodulated analog video for post analysis. In the Analyze Mode video demodulation screen, press the Frame Capture icon to capture a still image and save it to a .png or .bmp file. The OSCOR manual also provides instructions on how to activate the Baseband Out Port while demodulating an analog signal in order to record to an external device.

Taking the time to store information captured by the OSCOR can greatly assist with the documentation process after users are no longer on site.
