SignalScope XM offers a range of powerful measurement and analysis tools to enhance your productivity in areas such as acoustics (sound and vibration), audio, electronics, and electroacoustics.
Why Choose SignalScope XM vs SignalScope X?
SignalScope XM provides a Mac-only perpetual license solution for individuals, schools, and businesses at a reduced cost compared to SignalScope X's cross-platform licenses. App downloads and license purchases can be made completely outside of Apple's App Store, which may be preferred in some cases.
If you need to run SignalScope on iPad or iPhone, then SignalScope X is the best option. If you choose to purchase a SignalScope XM license, we offer discounted upgrade pricing for a corresponding cross-platform license.
