<p>Jirka: Added FNIRSI 1014D DSO</p> <hr /> <div>An '''Oscilloscope''' is an essential measurement device when doing analog computing. Nevertheless, even cheap entry level devices cost more than 200 EUR. This page shall document how to use oscilloscopes with [[THAT]] and gives recommendations about devices that are suitable for working with [[The Analog Thing]]. If you don't want to spend money on an oscilloscope, a [[Software Oscilloscope]] maybe an alternative.<br /> <br /> == Using Oscilloscopes ==<br /> To watch and measure the values and curves produced during an analog computation or simulation you need additional instruments. The Analog Thing contains a [[voltmeter]] as instrument to setup the coordinates or OP_TIME values. Depending on the [[modes|mode of operation]] in '''REP''' with predefined operation time or '''OP''' with infinite operation this display may be useful for static or slow moving values only.<br /> <br /> [[Image:DSO_Yt_display.png|thumb|typical Yt display of signals on a DSO]]<br /> To measure faster events or display signal curves the best tool is an '''oscilloscope'''. For longer operation times (REP, 0.1-10s) a digital storage oscilloscope (DSO) is preferred rather than an analog oscilloscope with a cathode ray tube (CRT). These DSO did get cheaper in the last years but useful DSO's with minimum 2 channels and XY mode are in the price range of about 150-300 € up. XY mode is useful for many applications and allow a better view of complex signals than displaying them just over the time in Yt mode. The typical Lissajous figures for example require the XY mode.<br /> <br /> [[Image:DSO_XY_display.png|thumb|typical XY display of the same signals above]]<br /> There are low cost oscilloscope on the market as well in the range of 40-100 € but these come with missing features and have mostly only one channel to display like DSO 138 or missing XY mode like DS 212/213. This is only partly useful with analog computations or simulations and all theses cheap handhelds have only a very small display. Some low cost oscilloscopes come without a display and are connected to a computer as display by software.<br /> <br /> == Requirements for Oscilloscopes with The Analog Thing ==<br /> [[File:Hantek IMG 0413.jpg|thumb|A nice entry level DSO: [[Hantek USB DSO]]]]<br /> === Minimum requirements (cheap devices) ===<br /> * analog oscilloscope with CRT display or software display while connected to computer<br /> * 1 or 2 channels<br /> * XY display mode<br /> * 100 kHz bandwith<br /> <br /> Recommendations:<br /> * [[Hantek USB DSO]] (79€ entry price)<br /> * [https://www.meilhaus.de/picoscope-2000.htm Picoscope] (125€ entry price)<br /> * [https://store.digilentinc.com/analog-discovery-2-100msps-usb-oscilloscope-logic-analyzer-and-variable-power-supply/ Analog Discovery 2] (280€ for academic)<br /> * [https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm2000.html#eb-overview ADMAL2000]<br /> <br /> Further cheap alternatives:<br /> * HS101 http://hscope.martinloren.com/HS101-oscilloscope.html<br /> * DroidOscillo https://hackaday.io/project/26360-android-oscilloscope-droidoscillo<br /> * DSO-138 https://www.reichelt.de/dso-138-oszilloskop-1-kanal-200-khz-12-bit-joy-it-dso-138-p209775.html?&amp;trstct=pol_0&amp;nbc=1<br /> * SmartScope https://www.kickstarter.com/projects/751733865/smartscope-reinventing-the-oscilloscope<br /> * FNIRSI 1014D DSO https://www.youtube.com/watch?v=yQKuHJELEOs<br /> <br /> === Medium requirements ===<br /> * 4 channels or separate trigger input<br /> * DSO type (digital storage)<br /> <br /> Recommendations:<br /> * [https://www.meilhaus.de/siglent-sds1000x-e.htm Siglent SDS1000X-E] (about 400€)<br /> <br /> == Alternatives ==<br /> A cheap alternative for beginners with low budget is to use a [[Software_Oscilloscopes|Software Oscilloscope]]. These solutions rely on your computer for all of the data processing and use a secondary device (such as an Arduino or sound card) for data acquisition.<br /> <br /> [[Category:Hardware]]</div>
