About Oscilloscope Pro
NFX Oscilloscope is a simple signal vs. amplitude analyser.
Currently there are two input options for the application.
**** PLEASE ENSURE THE GABOTRONICS DEVICE IS UP TO DATE!!
***** USB SUPPORT ****** (only for android 3.1 and greater)
The newest and best input option is a USB hardware device provided by Gabotronics. USB host mode has now been compatible since android 3.1, therefore most new phones and tablets will support USB host mode (Please check device). NFX Oscilloscope supports the Gabotronics Xprotolab/Xminilab, this has 2 analogue input channels and 8 digital channels and measures a tiny 2.5 x 4 cm!! The device it's self is a cheap portable alternative to most mainstream oscilloscopes, and has many different features. Connecting the Xprotolab to the NFX Oscilloscope provides a powerful and cheap oscilloscope platform for your portable needs. For more information on the Xprotolab or Xminilab click the following links.

Does not work with Xprotolab Plain on Galaxy S7 Android 6.0.1 with powered usb hub or unpowered adapter. With powered hub "no USB devices detected." At least I got refund easily. Please fix and then I'll purchase again. *Update* did not get refund!

I just received the Xminilab Portable. After playing with that hardware for a while to familiarize myself with its basics, I downloaded this app to my Nexus 7 (running KitKat) and connected the scope to the Nexus 7 by an OTG cable. The tablet makes for a gorgeous screen for viewing the waveforms. Using drag and pinch to move and change the size of the waveforms is very cool. I find it pretty intuitive. Within a few minutes of playing with the app I could do all of the basics I need.

I also use this app, albeit on my Samsung Galaxy S3, with my Gabotronics Xprotolab scope. It takes the scope to a whole other level. It makes using the xprotolab a bit easier. Plus it looks so cool. I showed and demonstrated the app and the device to my automotive instructors and classmates, and it blew their minds. Lol, overall great app, but even greater with an Xprotolab.

I use this app with xminilab and it works flawlessly. When i first installed this app, i assumed, i could store my recordings, but found out I couldn't. Asked the developer whether he had plans of adding this function and he responded promptly. He letting me know it was on the cards. Shortly after the app come out with the ability to save to csv. I was also emailed, letting me know of this update. I'm a happy customer.

I see the xproto and xmini almost identical. Xproto is working fine so I wonder will the xminilab also work? So that I can put away the magnifing glass man!

Not fancy, but gets the job done and controls are slick. For my purposes, being able to manually set the sync delay would be a boon. (Analyzing FSK)

Great scope paired with the $20 Xprotolab Plain. Has a bug with display of the trigger level marker on my device, but hopeful to get it resolved soon. As mentioned in another review I would love to see some sort of Auto zero level or auto horizontal markers like in the xscopes app on PC. Also, the dual meter function is high on the wishlist. Hoping this app continues to develop rather than dying on the vine like so many others.
