Oscilloscope App Description

"I use this for analog, and audio measurements. Attach an Apple USB adapter and a $40 stereo A-D converter available online, and my iPad is like a $300 O'Scope." -thymeout- Oscilloscope app is great for analyzing audio range signals, or learning oscilloscope measurement basics. The interface includes many standard oscilloscope controls, such as: triggering, time and voltage per division, signal measurement cursors, and more. The app incorporates a signal (function) generator capable of generating sine, square, triangle, and sawtooth waveforms of up to 22 KHz. Calibration to an external reference signal is supported, guaranteeing the accuracy of measurements. Input can be acquired via the built-in microphone or an external mic/probe connected to the headset connector. For best results, use an external audio interface connected to your device dock. This allows for standard audio equipment to be connected, as well as for dual channel input. Oscilloscope probes also be connected (using a BNC connector). When feeding external signals via probes, you should take care not to exceed 1V AC voltage. Currently iDevices support only AC input. For up-to-date information on feeding signals and currently supported audio interfaces, please visit http://oa.onyx3.com Feature Highlights: ● Real-time waveform display (60 FPS) ● Triggering modes: Normal, Auto, Single ● Set trigger level and pre-trigger time ● Dual channel signal generator ● Reference signal calibration ● Pause function to get a screen capture ● Export traces as text file for further analysis ● Measure signal data using cursors ● Use "finger pinch" on screen to set voltage and time base ● Double tap screen to enter Black Panel mode ● Three color themes to choose from ● XY mode for viewing Lissajous figures ● Frequency range 20Hz-22KHz ● iPhone X ready

  • Love it!

    By Donnie Herman
    Best on the app store for sure! So thankful this is still supported! iOS 12 update! :)
  • Great for monitoring Eurorack levels!

    By D77
    This is a great app for the money! I read the info and took a chance on how well it could read DC values in order to monitor control voltages, and it does great! I paired my Eurorack rig with an ES-8 interface and can directly monitor audio values and control values. Takes a second to scale onto the screen with proper amplitude to get the idea, but it's not inaccurate and not hard to calibrate. Saved me $400 on a Data module (which is great and has much more functionality), but for monitoring without a computer, this app is the WINNER!
  • Great works with ES-8 D.C. Coupled interface

    By flux302
    This is the best app I've found so far that works with expert sleepers es-8 audio interface (es8 has D.C. Inputs and outputs ) the buffer settings could be larger for better LFO viewing but this is by far the best I've seen. Controls could be a bit better and there is no analog persistence mode to make it look pretty. But over all it's really great for the money. Hope this continues to get updates!
  • My favorite app

    By colordeaf
    This to me is exactly the ideal product of an app development community and app marketplace. I love this thing. This makes any iOS device an double as an incredibly useful tool in a new, unique way. That is to say it's also the best app among the category of all oscilloscope apps I have tried. The UI is super simple, to the point of actually being beautiful. The pinching is a little hard to get used to. I would slip at first and adjust the offset when I was trying to adjust the voltage. Now I still slip a little when adjusting the time base, but it's easy enough to correct. And Auto makes it easy to not even worry about any of that. Thank you. Well worth the price.
  • Annoying interface

    By joost4u
    This app could do much better with on screen controls for timebase and channel gain settings. The generator levels seem unadjustable. Extremely annoying is the scale changes do not adhere to standard scope 1,2,5 sequence so you end up with silly fullscale and time settings. This app misses thr mark by a mile, i am chucking this.
  • Usable for Sound Synthesis; Needs iOS9 Slide-Over feature

    By dataBANG
    🎹〰🎛 Decent app to observe visual changes when adjusting knobs, but there's a privileged problem of needing more than one device to observe the waveform while adjusting the controls of a sound generator. Sure, you can switch between the app screens, but that's not ideal. Now! Maybe the ONYX devs can incorporate the new Slide-Over functionality that iOS9 brings—this would make this software more usable on a single device. 🗣dB!
  • Works Great! Used it all weekend instead of my bench scope.

    By GweepDad
    Nice job with this app! I would like to see a few more features but honestly it does way more than I expected! I would like to see integration with Audiobus or Inter-App Audio. The cursor icons could be a bit bigger on the iPhone. The large beefy border of my Pelican case make it more difficult to grab the cursor handles. Nice work!

    By Leo engineer
    This is a great App for low frequency work! I am porting a special low pass filter stereo music signal using the recommended input devices for an XY music display, and using Airplay to send to my TV. All the App features work great and this is a really fun App for the oscilloscope aficionado's out there like me.
  • 22Khz Limit, too bad.

    By illdub
    The 22KHz limit is a huge negative. All my waveforms end up looking like square waves. Increase the limit and the functionality would really improve. (I'm mad at myself since I didn't notice the limit before purchasing. Don't be like me, read the description carefully)
  • Only works under 20kHz

    By Samoan27
    I got this app to work with ultrasonic transducers but I found out once I started working with it that the shortest time step you can have is 0.5 ms. So at 20 kHz you have 10 peaks per square and is pretty useless beyond that point. I'm working with 450 kHz and the display is just a yellow blur. I'd give this app five stars if it worked for the frequencies I needed (which most oscilloscopes would) but since it was a waste of money for my needs I give it two stars.
