SignalScope 1.8.5

SignalScope is an audio signal analysis software designed to work with Mac OS X compatible audio hardware.
It functions as a spectrum analyzer as well as an oscilloscope. SignalScope was designed to make meaningful measurements with easy-to-use controls.
Main features:
- SignalScope 1.6 added support for multi-channel audio devices
- Choose from all input signal formats supported by the current audio device
- Invert polarity on either input channel
- User-definable full scale voltage allows for calibrated measurements
- Select either channel (or both) of the audio device to be used for measurements
- Units of volts
- Save trace data to disk
- Print to paper or PDF
- Save control settings when SignalScope quits
- User-definable display colors and line widths
FFT Analyzer
- Turn guardbanding off to view spectral content up to the Nyquist frequency (half the sample rate)
- Choose from ten possible frequency spans (dependent on the current sampling rate)
- View spectra with up to 4096 lines of resolution
- Linear and dB vertical scale
- Auto and manual scaling of the vertical (voltage) axis
- Linear and logarithmic frequency scale
- Cursor for measuring frequencies and amplitudes within the spectrum
- Peak track cursor function
- Uniform, Bartlett, Blackman, Flat top, Hamming, Hann, and Rife-Vincent 2 data windows
- Linear and exponential averaging
- Peak hold averaging
- Spectrogram
- Choose from five possible frequency spans (dependent on the current sampling rate)
- View spectra with up to 4096 lines of resolution
- Uniform, Bartlett, Blackman, Flat top, Hamming, Hann, and Rife-Vincent 2 data windows
- Linear and dB voltage (color) scales
- Manual scaling of the horizontal (time) axis
- Optional grid over spectrogram display
- Selectable color schemes (choose from grayscale white-on-black or black-on-white, or use existing color preferences
Oscilloscope
- Auto and manual scaling of the vertical (voltage) axis
- Independent vertical offset of signal waveforms
- Triggering on positive or negative slope
- Automatic capture of pre-triggered data
- Manual adjustment of trigger level
- Independent trigger source selection for each input channel
- Continuous or single shot triggering
- Manual scaling of the horizontal (time) axis
- Dual cursors for measuring signal periods or time between peaks
X/Y Plotter
- Auto and manual scaling of both (voltage) axes.
Version restrictions:
- 30 days trial.
Enhancements:
- SignalScope includes an updated registration engine and allows for proper cloning of multi-computer licenses.
