Data Acquisition

In addition to real-time analysis, SignalScope Pro can store acquired data in tab-delimited text files, MAT-files, or images for later retrieval from your device. A data file can be saved from within either of the spectrum analyzers, or from within the oscilloscope tool, by tapping the action icon in the toolbar at the top of the screen. You can enter a custom filename, which will be recalled each time you save another file. When a file already exists with the chosen filename, a numeric suffix will automatically be appended for fast and easy file saving without additional typing.

• Text files should be opened with UTF-8 text encoding (special symbols, like the "micro" symbol, might look strange, otherwise).
• Saving dual-channel audio data to a text file with a long time scale in the oscilloscope can take a long time (up to four minutes, or so), so please be patient. Saving .mat files is much faster.

SignalScope Pro shares its data by running an http server on your device. By entering the server's local IP address in a web browser on your Mac or PC, you can download saved data files. Your device must have an active Wi-Fi network connection. You access the file server settings, and determine the correct IP address, by tapping on Data File Server in the main options screen.

If SignalScope Pro is able to determine the external IP address of your network, and if your local network router is properly configured, you can also access the data files on your device via the web.

SignalScope Pro also features a built-in file browser, which allows you to see which data files are still being stored on your device and delete them, if desired. This browser can also be accessed from the main options screen.

Images are stored in the device's photo library, which is accessible from the built-in Photos app.

The Level Meter can capture and share measured sound levels and supporting information, such as date and time, as well as the current GPS coordinates.

The Level Meter does not capture data to text or MAT-files, like the other tools. Instead, it shares its data via email or twitter. The Level Meter can also save sound levels as image files, or as overlays on new or existing photos in your photo library. On the iPhone, The Level Meter can even use the built-in camera to capture an image associated with the current measurement, and the sound level can then be overlaid on top of the photo, along with any other information you type in.
