  1. 'm an enthusiast looking to mainly work with digital and maybe occassionally on minor Analog Circuits as well. I was considering getting the Analog Discovery 2, but since my primary focus is digital someone recommended me the Salea over the AD2. I was told that the sample buffer in the AD2 is outdated and too small for anything useful. On the other hand even though I didn't get an exact number for this on the Salea, they seem to offer direct streaming to PC memory therefore limited only by the amount of RAM. Can someone please clarify if AD2 suffers from this limitation or if it has direct streaming support as well through Waveforms? Are there any workarounds for the small sample buffer? Thanks for reading.
  2. Hi, using the instrumentation protocol I was able to issue a "read command" to the Oscilloscope and receive the following message. 113 {"osc":{"1":[{"command":"read","statusCode":0,"binaryOffset":0,"binaryLength":4876,"acqCount":220,"actualSampleFreq":24381324,"pointOfInterest":2062,"triggerIndex":0,"triggerDelay":84572929674,"actualTriggerDelay":84572929674,"actualVOffset":43,"actualGain":0.25,"wait":0}]}} 130C 66AA8;;68>8>DD>;;;>A;A>;G;>8;;6>6A;6;3DD;;8GAA8;;>>AD;D;8>A;86G;DA3;8>8;>ADA>;GG;AA;8;8>A3A>G68A>>>8>6686>D;;>A;DG;D88;A>8;;;8>A>>8>>A8A86D>83D386;;>>>>8A;;AA8;A;;>6;G>D>;>>3J>>A6AD88;AAG3;>DA>;;8>;88>A>>AD6;6;AAG;;;6>D;6>68A>>>>8>88;;DA>A;;;AA8>A66>6>D;;>>;8686A>>8;A>;;AA;8;;A;D>A>8;A>A8A3>3GD>>>A>>D8A8A838AAD>AA;A86>;D>88A;A;3;3D>3D>88A8>;8;J;6>>>A6GA8;;688D>;>A>>883;DA88D>6;J86>;;>>A;>;>>;D3>6>;DADA>>A;A;;;8D8AA>;>;;A;>>>A;A6>;A6>88DADA>>6>8>A8D>;;>;3DD>A6>>A;;8>AJ36;8>D8A>>>;;>A83A6;;;;;3;88DA>68>;>3DAA>;;6AD>6>>>>DD;A8A;A6AG>;>3;D;A8G;8D>;>>;>D63>8>;>8D6;ADA;>>;AA>>ADA3>8DA>>66;D>;A>68;D>>;D8>;A;6D;8AA;>6A>>>A8>6D8>;>38;A8;8;>>;;>;A6;>>6D3;AD>>A;88D;;AA;A;>;8>;;8;8A>AD;D>8>>;>D;66D0>>386D>;DA>>;>3;AA8>;G88>>>688DAA>>;>>>>>;686>668A8>D>>A>8AA8;;;>>>A68G>>AA;>;;>D88;8>;>A68>8AD6G;D>;;;AD;88>8D;>AAA>8DA;88;6D8A>AA>A>6>;>>D88ADA>>D;A>8>A;AA;8;6>6;A8J;;>8;;;;GA8>D>8A>A>>;;>;>DA;;A;8;6A>6;8GAA>A>688A;8;383D>6A6>8>GD886;AAA;>A;A>;;AD6>3>>>83G3>D>;;;>;>8G>6A>>6;;>>->D;8>68>;6DGA8A86>A-8;;>3A8;8;A66;;;;D>68A;8>88AA>A;>8;;6;>8;8G>A8;>>;>>8;D;;AA;3>A6;D>>>;;>D;8D;A8;A;>8;DAG;68G86>>D>A6;A8>D8;>;;>A;;6D;6>6>8A>A;8D>;A;>>>6;6>>>A>>G8>;>;>8D8>86DDD>8D;;A63D6;A;>;86;8;D8;>DA;D;>>>JD88;>G>;A;>;>>A8DD6AAA>;8>>A 0 For your reference, this was the command i used to read from the oscilloscope: {"osc":{"1":[{"command":"read","acqCount":101}]}} I am having trouble decoding the data CHUNK of length 4876 bytes (130C). As far as I understand, the CHUNK is encoded using "I16" (from the docs : "The binary data type and resolution are defined in the device enumeration and units are in mV"). First of all, if I well understand the payload of the message above has 1218 characters, for a total of 9744 bytes, which does not seem to match with the 4876 mentioned before. Secondly, if I then take these ASCII values, convert them to integer and try to compute a single number using a pair of consecutive bytes, the final number I get are not nearly close to the expected signal (which by the way is a square wave at 1kHz). I guess my question is very simple, how is the CHUNK of data encoded? Can anybody give me an example of how to decode this data perhaps using the first few bytes in the payload above ("66AA8;;....."). Thank you!
