ARC Spectrum Analyser
The zoom option is probably the best part of the software. It enables you to setup a large search range. After a while you can then use the zoom option to take a closer look at activity shown in the analyser. All acquired data is stored so the zoom option or resizing the window will not delete your data like other programs!!
Here is an example of the zoom option:
This screenshot is longtime analysis of the UFH cellular band (461.31-465.99 MHz) with 20kHz steps. You can see activity at certain frequencies but because resolution of your screen is limited it's not easy to recognise seperate frequencies. The zoom option will show exactly the frequencies that were used.
