SignalScope Basic 2020 offers a basic 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.

Features:
- 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 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).

Basic Tools:
- 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.

SignalScope Basic 2020 will receive major upgrades, consistent with those available in the SignalScope X Basic 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 iOS.

Version History - Faber Account access has been added to SignalScope Basic 2020 to register the app for eligibility for special discounts on select SignalScope X version 13 licenses. Creating or signing in to a Faber Account is optional. 11.5.20 Apr 22 - Support added for the latest Digiducer USB Digital Accelerometer models.
- Updated to improve stability on macOS 14, Sonoma.
- Fixed a crashing bug on iOS 12. 11.5.19 11/16/2023 - Corrected an issue with Unicode text characters that could prevent MAT files from being successfully opened by MATLAB 2020b or newer.
- Minor cosmetic improvements. 11.5.18 10/16/2022 - A bug that would cause FRC (frequency response correction) to be reset in other channels when switching it on or off has been corrected.
- Minor cosmetic improvements. 11.5.17 10/03/2022 - Minor cosmetic improvements. 11.5.16 09/28/2022 - Fixed a text and audio data export bug that would cause the app to crash when there was no data in some analyzers. This could happen when triggering was enabled and no data was acquired on some or all channels.
- The spectrogram cursor peak track works correctly with spectral smoothing applied. 11.5.15 09/13/2022 Extra, temporary copies of files loaded from external sources (e.g. iCloud Drive) no longer accumulate in the Inbox_2 folder. 11.5.14 08/12/2022 External file loading has also been made more robust on iOS. 11.5.12 08/11/2022 Fixed a bug in which the XY Scope might not start running as expected. 11.5.10 06/23/2022 - Fixed a bug with input sometimes not starting in the calibration screen. 11.5.8 04/08/2022 - Fixed a bug that could cause incomplete importing of frequency response data for input channel frequency response correction.

- Fixed a bug that prevented the FFT Analyzer from loading selected data from loaded data files at launch.
- Fixed a bug with the cursor horizontal bar and peak track selection menus.
- Minor bug fixes and performance enhancements. 11.5.6 02/15/2022 - A list of the most recent articles and news items on the Faber Blog is now accessible from the Info menu.
- Minor bug fixes. 11.5.5 12/29/2021 - Corrected an error in assigning the default microphone and headset sensitivity to older iPad models. 11.5.4 12/17/2021 - Updated support for new M1 iPad Pro models.
- Added support for the Digiducer 333D04 USB digital accelerometer.
- Added a correction factor, based on sample rate, for Digiducer accelerometers and The Modal Shop's 485B39 USB ICP signal conditioner.
- Additional bug fixes and cosmetic/user experience improvements. 11.5.3 12/15/2021 - More robust triggering in all tools that support it.
- Mac: Improved support for zoom/pan in line and surface graphs via two-finger pinch/drag gestures on the track pad. The mouse scroll wheel works for panning zoomed graphs.
- Additional bug fixes and cosmetic/user experience improvements. 11.5 10/05/2021 - Improved support for audio interfaced with DC-coupled inputs, including optional DC offset correction and DC blocking filters per input channel.
