SpectraVue

SpectraVue is a software application that you can use to view and analyze spectrum. It generates 2D and 3D representations for various signals obtained from your sound card or an external source.

After a brief and uneventful setup procedure that shouldn't impose any difficulties, you are greeted by a large window with a clear-cut structure that shows the 2D plot.

You can switch the viewing mode to 3D plot, V or H waterfall, combo, continuum, phase or raw data, as well as specify the FFT average, FFT/BLK, V scale, auto scale, memory channels, along with the volume level.

It's possible to save the FFT to an Excel file, export the graph as an image file (.bmp, .jpg, .jpeg or .png) or print it directly, make the main frame stay on top of other windows, select the input device, as well as set up the SDR-IQ, such as firmware updates, the network interface, and bandwidth filtering.

Similarly, you can tinker with data output parameters, like manual recording mode, sound card device, and timestamp file name. SpectraVue also lets you customize settings for the external radio, such as serial port and bit rate.

General configuration options revolve around the FFT window type, display unit and speed, 2D graph color mode, cursor mode, JPEG compression quality, mouse click resolution, pulse mode, and so on.

No error dialogs were shown in our tests, and the software utility didn't hang or crash. Its impact on the overall performance of the machine was minimal, since it needed low CPU and RAM to work properly. Although it doesn't include more intuitive options for less experienced users, SpectraVue provides skilled ones with powerful configuration settings to help them view and analyze spectrum.
