anil Posted February 25, 2015 Share Posted February 25, 2015 I watched this video on Getting Started However, I do not see the same waveforms as in the video. Is my analog discovery working correctly? Link to comment Share on other sites More sharing options...
attila Posted February 25, 2015 Share Posted February 25, 2015 Make sure to connect the AWG1 (W1, solid yellow) to Scope Channel 1 Positive input (1+, solid orange). In the picture it seems that AWG2 (W2, white yellow) is connected to scope. PS: In case you are working with higher frequency signals, twisting the scope + with - and awg with gnd wires helps in radiant noise rejection.

anil Posted February 28, 2015 Author Share Posted February 28, 2015 Thank you for the reply, it worked. Also, what is the small hinged plastic capsule provided in the Discovery case? Link to comment Share on other sites More sharing options...
attila Posted March 1, 2015 Share Posted March 1, 2015 That is a ferrite bead (RF choke) for the USB cable to filter high frequency noise signals between the computer and device. Link to comment Share on other sites More sharing options...
anil Posted March 3, 2015 Author Share Posted March 3, 2015 Thank you for replying. Where should I put it - is it a sleeve that snaps around the cable and should it be close to the computer, or close to the Discovery? If you have a picture that would be great. That is a ferrite bead (RF choke) for the USB cable to filter high frequency noise signals between the computer and device. Link to comment Share on other sites More sharing options...
attila Posted March 3, 2015 Share Posted March 3, 2015 Theoretically it should be laced close to the computer side of the cable to filter the high frequency noise generated by this, to prevent the USB cable acting as RF emitting antenna. But I don't think it makes too much difference with nowdays computers and laptops, even if you don't use ferrite bead. For instance fluorescent bulbs (at low frequency) are much stronger radiation sources. Link to comment Share on other sites More sharing options...
