SignalScope Pro 2020 offers a professional tool set to meet your measurement and analysis needs as an engineer, consultant, educator, student, researcher, or savvy hobbyist in areas such as acoustics (sound and vibration), audio, electronics, and electroacoustics.

SignalScope Pro 2020 requires at least iOS 12 or macOS 10.15 and runs beautifully on Mac, iPhone, and iPad with a single purchase.

SignalScope Pro 2020 will receive major upgrades, consistent with those available in the SignalScope X Pro Tool Set subscription, through calendar year 2021, after which it will receive maintenance updates for a limited time. It can be used indefinitely thereafter on a compatible version of macOS, iPadOS, or iOS. We cannot predict compatibility with future operating system versions.

• Analyze signals coming from the Mac or iOS device’s current audio input device.
• Assign engineering units to your input signals and calibrate external transducers for accurate measurements.
• Assign input channel units and sensitivities for individual USB Audio devices.
• Direct support for Digiducer digital accelerometers and 485B39 USB ICP signal conditioner from The Modal Shop.
• Direct support for miniDSP UMIK-1 measurement microphone and EARS headphone/IEM measurement system.
• Nominal acoustic sensitivities included for iPhone and iPad built-in microphones, voltage sensitivities for headset input (including the Lightning-to-headset adapter included with recent iPhone models)
• Manually switch between available audio input and output sources.
• Load microphone frequency response data (FRD) and apply frequency response correction (FRC) to FFT-based measurements.
• Manually adjust audio sample rates, even up to 192 kHz, depending on input hardware.
• Save acquired measurement data to CSV, tab-delimited ASCII text, or MAT files.
• Save high-resolution analyzer display images to PDF files.
• Retrieve your data files from your device via Files (iCloud Drive), iTunes File Sharing, or through a web browser on another device. Files may also be opened in other compatible apps (e.g. Mail, Notes, Numbers, Dropbox, etc).

• Oscilloscope - Basic oscilloscope and triggering functions.
• FFT Analyzer - Spectrum analyzer with user-settable frequency limits and basic triggering
• 2D Real-time Spectrogram Analyzer
• XY Plotter - Create Lissajous curves on your Mac, iPhone, or iPad.

• 3D Real-time Spectrogram Analyzer - Stunning live visualization of incoming data
• Octave-band Analyzer - Whole and 1/3-octave RTA
• Level Meter - Overall signal level meter
• Max Levels - Traffic-light-style, frequency-selective sound level threshold meter
• Noise Dosimeter
• Data Recorder - Stream up to 8 channels to WAV, AIF, or CAF audio files.
• Stereo Signal Generator

• Dual-channel System Analyzer (Dual FFT analysis with support for Frequency Response Magnitude/Phase, Phase Delay, Group Delay, Coherence, Impulse Response and Cross-Correlation)
• Room Acoustics Analyzer (T20, T30, T60, nonlinearity, EDT, Early Decay Time, Center Time, Clarity, and Definition in various frequency bands, manual or automatic adjustment of Schroeder integration limits)
• MultiTool - Powerful data monitoring and project management (Add up to 2 subtools on iPhone, 6 subtools on Mac or iPad Pro with 10.5-inch or larger display, 4 subtools on other iPad models, and save an arbitrary number of different configurations for easy recall at a later time.)
• Multi-channel Audio File Player - Analyze pre-recorded data.

• Data logging support in the Level Meter, Octave Analyzer, and Noise Dosimeter
• Percentile exceeded sound levels in the Level Meter and Octave Analyzer
• NC, RNC, and NR references curves, NC, SIL, and NR values in the Octave Analyzer
