» Read moreFollowing in the footsteps of SignalScope Pro, SignalScope has now been enhanced for iPad users with native iPad support. SignalScope’s FFT analyzer and oscilloscope now support drawing on an external screen with a compatible video output adapter. The original iPad supports external screen resolutions up to 720p and the iPad 2 supports resolutions as high as 1080p and even 1920×1200 with compatible hardware. Video output support is not supported on iPhone or iPod touch. SignalScope can be upgraded, via in-app purchase, to the full functionality of SignalScope Pro. Alternatively, additional tool upgrades, such as the octave-band spectrum analyzer or signal generator, may be purchased individually. Like the Pro version, SignalScope now supports PDF file creation, in-app file previews, iTunes File Sharing, […]
