For sale here is a used Digilent Analog Discovery Oscilloscope, second version, in working condition. Apart from being a 100MS/s USB Oscilloscope, it has many other functions - Logic Analyzer, Data Logger, Network Analyzer, Impedance Analyzer, and more. Please see the product website at the following link for more information - https://digilent.com/reference/test-and-measurement/analog-discovery-2/start . Inside the box: Digilent Analog Discovery 2 One 2x15 signal cable assembly Micro USB cable For upto about 4-5MHz the included 'wire probes' may be sufficient. For better signal integrity, you may use a BNC adapter to connect BNC probes. You may buy a BNC adapter like the one at https://digilent.com/shop/bnc-adapter-for-analog-discovery/ . You can also make one yourself and here are two websites for ideas - https://www.eevblog.com/forum/testgear/juntek-dpa-2698-10mhz-signal-amplifier-digilent-analog-discovery/msg3067172/ and https://atadiat.com/en/the-multi-function-instrument-analog-discovery-2-review/ The pictures in the gallery are those of the item you will receive. I have also uploaded a picture of, 1.) the AD's signal generator giving out 5MHz, 2.) it's oscilloscope displaying that and, 3.) the way I made the connection between the AD's waveform 2 output and it's channel 1 oscilloscope. I have two more of these - all are used and in good condition. If you need more than one then, please email me. Thank you.
