Oscilloscope Pro
NFX Oscilloscope is a simple signalvs.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 deviceprovidedby Gabotronics. USB host mode has now been compatible sinceandroid3.1, therefore most new phones and tablets will support USBhostmode (Please check device). NFX Oscilloscope supportstheGabotronics Xprotolab/Xminilab, this has 2 analogue inputchannelsand 8 digital channels and measures a tiny 2.5 x 4 cm!! Thedeviceit's self is a cheap portable alternative to mostmainstreamoscilloscopes, and has many different features.Connecting theXprotolab to the NFX Oscilloscope provides a powerfuland cheaposcilloscope platform for your portable needs. For moreinformationon the Xprotolab or Xminilab click the followinglinks.http://www.gabotronics.com/development-boards/xmega-xprotolab.htmhttp://www.gabotronics.com/development-boards/xmega-xminilab.htmSo match this application with the cheap device from gabotronicsandyou will get a great portable oscilloscope!Note: Only the analogue channels, logic Channels and tonegeneratoris supported on the xprotolab/xminilab/xprotolabplainSpec list for xprotolab:2 Analog InputsMaximum Sampling rate: 2MSPSAnalog Bandwidth: 200kHzResolution: 8bitsInput Impedance: 1MΩBuffer size per channel: 256Input Voltage Range: -14V to +20VCurrently the USB mode has been tested on Samsung Galaxy Nexus,Asus Transformer , Asus Nexus 7 , Samsung Galaxy S3There has been problems reported with android version 4.3 andUSBhost, there is a major bug in the release, which is set tobeupdated at some point in the future.Please note : Most devices will need a OTG cable to enable usbhostmode. See phone specific instructions for moreinformation.***** Microphone SUPPORT ******The second option is the microphone input to the androiddevice.This can be used to attach a scope lead to the jack socket.Moreinformation can be found at the following website.http://www.instructables.com/id/A-Preamplifier-for-Smartphone-Oscilloscopes/Features include, triggering for different impulse andcontinuoussignals. In addition to this there is level measurementandfundamental frequency readingsIt is possible to control the amplitude, time/div and triggerlevelwhilst monitoring. Settings included trigger directions,samplerates and voltage span calibration.Have a look at this blog for more scope cable information fromafellow user of Nfx oscilloscope.http://www.instructables.com/id/A-Preamplifier-for-Smartphone-Oscilloscopes/Head to my blog for more information on the NFX Oscilloscope.http://nfxdevelopment.wordpress.com/If you are unhappy in anyway with this product, feel free tocontactme and I will help all I can, if I cannot help I will offera refundat any time (even past the 15 minute google refundmark)Email : [email protected] you for purchasing, I hope you enjoy!

Oscilloscope Mate v1.7
Designed for those who have older analogue oscilloscopes buthavenoonscreen measurement capabilities. I made this after gettingfedupof using a calculator all the time to try and work outexactlywhatI was frequency I was seeing on screen!!. So I decidedto makeanAndroid App to do it all for me and it kind of grewfromthere!Found it to be more useful than I thought as I nowfindmyselfusing the scope more and more now I understand whatI'mseeing!Have fun and let me know if anything is wrong withtheApp...feedback is always welcome. Features: - FrequencyCalculationinHz, kHz, MHz, GHz etc - Rising/Falling Edge TimeCalculation.-Phase Calculator displaying results in Degrees,Radians,Quadrants,Frequency and time offset. - RMS CalculatordisplayingRMS valuesof Square Waves (Various Duty %), Sine Wave,TriangleWave,Sawtooth Wave. Includes adjustment for probeattenuation. -DutyCalculator of a square wave based upon pulseon/pulse offduration.- Amplitude Calculator based upon voltage,number ofdivides andprobe attenuation. - Ripple Calculator baseduponvoltage, probeattenuation etc (Added some ATX and USBinformation)GeneralFeatures: - Has a 'Keep Alive' option for thescreen in themenu. -All answers from the calculators can be copiedto clipboardif youwish to move the answers to a 'proper' androidcalculatoretc. -All answers can be Shared amongst other AndroidApps thatsupportthe Androids 'text' format.

Hairspring 1.2.2
Hairspring turns your device into apowerfulmechanical watch timing machine. It measures the precisionofmechanical watches, with an accuracy of at lease ±1s/day,byanalyzing the tick-tock sound using the microphone of the device.It supports a wide range of frequencies, covering almostallmechanical watches available on the market:- 14,400 VPH- 16,200 VPH- 18,000 VPH- 19,800 VPH- 21,600 VPH- 23,400 VPH- 25,200 VPH- 28,800 VPH- 36,000 VPHIn case you don't know your watch's frequency, you mayusefrequency auto detect.The measuring time can be set from 30 seconds to 3 minutes,toget a balance between response time and accuracy.An oscilloscope shows the audio waveform in real time. It'squitehandy for monitoring the status and diagnosing somecommonproblems.The result is plotted in a chart, which can be saved forlaterreference. Also, it can record and save a long-timemeasurement,e.g. for 12 hours, to analyze the long-time performanceof thewatch.To use Hairspring, just place the microphone tightly close tothewatch back, then set the parameters. After collecting enoughdata,the result will be shown.A detailed usage guide can be found here: http://www.diversminds.com/Hairspring/Hairspring.php*** PLEASE NOTE ***- This is a Lite version of Hairspring, with the accuracy limitedto1 min/day.To get accuracy of 1 s/day, you need to upgrade to premiumversion,using in-app purchase.- Hairspring requires a sensitive microphone. Make sure itworkswith your microphone before upgrading.
