It can be used with a phone or tablet without a computer.This means there is no any wired connection to the phone or tablet, which can guarantee the safety of your device.
The oscilloscope is the most frequently used, most flexible device for electric measurements.
It visualizes an electric potential over time function, producing much more information than other potential and current measurement methods.
With an oscilloscope the following quantities can be either directly or indirectly measured:
direct voltage, alternating voltage, direct current, alternating current, time, time delay, phase, phase difference, frequency to view live waveforms, make measurements.
Demo mode available.
Displaying the audio waveform captured from a microphone.
Accelerometer waveform, x y z.
Measure: frequency, min/max, peak-peak
FFT for microphone input.
Shows trigger level information
Save screen captures from your instrument onto your mobile device
Save signal to file in csv format.
Control the following functions
• start/stop/single acquisition
• change time/div
• change volts/div
• turn channels on/off
• select trigger type/level
• screen zooming
• double click on triggers sets them to zero level
Android 2.3.5 and up
Please email firstname.lastname@example.org to report bugs, ask questions or give us your feedback.
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.
So match this application with the cheap device from gabotronics and you will get a great portable oscilloscope!
Note: Only the analogue channels and logic Channels are supported on the xprotolab/xminilab, future updates will bring digital and tone generator support.
Spec list for xprotolab:
2 Analog Inputs
Maximum Sampling rate: 2MSPS
Analog Bandwidth: 200kHz
Input Impedance: 1MΩ
Buffer size per channel: 256
Input Voltage Range: -14V to +20V
Currently the USB mode has been tested on Samsung Galaxy Nexus , Asus Transformer , Asus Nexus 7 , Samsung Galaxy S3
There has been problems reported with android version 4.3 and USB host, there is a major bug in the release, which is set to be updated at some point in the future.
Please note : Most devices will need a OTG cable to enable usb host mode. See phone specific instructions for more information.
***** Microphone SUPPORT ******
The second option is the microphone input to the android device. This can be used to attach a scope lead to the jack socket. More information can be found at the following website.
Features include, triggering for different impulse and continuous signals. In addition to this there is level measurement and fundamental frequency readings
It is possible to control the amplitude, time/div and trigger level whilst monitoring. Settings included trigger directions, sample rates and voltage span calibration.
Have a look at this blog for more scope cable information from a fellow user of Nfx oscilloscope.
Head to my blog for more information on the NFX Oscilloscope.
Version 6 finally brings USB support in collaboration with the gabotronics Xprotolab. This now means we are not tied down to the maximum sample rate of the phone!!! Head over to their website to see the full specs on the product.
If you are unhappy in anyway with this product, feel free to contact me and I will help all I can, if I cannot help I will offer a refund at any time (even past the 15 minute google refund mark)

Use it if you are developing an app that uses sensors, to measure your environment, to learn about the physical phenomena that these sensors measure, or simply if you are curious.
Supported sensors are:
- Uncalibrated Magnetic
- Orientation (*)
- Gravity (*)
- Linear acceleration (*)
- Rotation vector (*)
- Game Rotation vector (*)
- Geomagnetic Rotation vector (*)
- Bluetooth signal strength
- Wi-Fi signal strength
- Step Counter
- Step Detector
- Significant motion
- Relative humidity
- Ambient temperature
When it makes sense, you can plot the X, Y, and Z component, and the magnitude. For Wi-Fi and Bluetooth you can plot the strongest signal, or a chosen network.
Not all Android devices have all sensors, and some even have `fake' sensors that always return zero. The sensors indicated with (*) are `virtual', `synthetic' or `fused' sensors that combine or process data from other sensors.
SPICE is an acronym for Simulation Program with Integrated Circuit Emphasis
and was inspired by the need to accurately model devices used in integrated circuit design.
DroidTesla simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL)
in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordance
with KCL and then proceeds to solve for the unknown quantities using various algebraic
techniques such as Gaussian elimination and sparse matrix techniques.
For non-linear components, such as the diode and BJT ,DroidTesla engine searching for the approximate solution by making an initial guess at an answer
and then improving the solution with successive calculations built upon this guess.
This is called an iterative process.DroidTesla simulation uses the Newton-Raphson iterative algorithm
to solve circuits with non-linear I/V relationships.
For reactive elements(capacitors and inductors),the DroidTesla uses numeric integration methods to approximate the state of the reactive elements as a function of time.
DroidTesla offers the Trapezoidal(I'll add a GEAR method later) integration methods to approximate the state of the reactive elements.
Although for most circuits, both methods will provide almost identical results,
it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate.
DroidTesla for now can simulate:
-Potentiometer (available only in pro version)
-Light Bulb (available only in pro version)
-Ideal operational amplifier
-Bipolar junction transistor (NPN PNP)
-MOSFET N-channel depletion
-MOSFET N-channel enhancement
-MOSFET P-channel depletion

-CCCS - current controlled current source
-VCVS - voltage controlled voltage source
-VCCS - voltage controlled current source

-Triangle wave voltage source (available only in pro version)
-Two channe oscilloscope (available only in pro version)
-SPST Switch (available only in pro version)

oscillators you have to put a small initial value on some of the
reactive elements.(see the examples)
