  1. Hi folks, I'm currently hacking a 433Mhz temperature probe, and attempting to intercept the reading using a standard 433Mhz receiver, such as the Sparkfun RF Link Receiver. Using WaveForms (desktop) I can record the Logic Analyzer output, and can see the single fine. I'm currently in the process of parsing the bit stream. The signal is repeated every 59 seconds. However I need more samples, and the manual translation of the square wave to 0/1's is tedious and time consuming (and error prone). I'd like to create a script that will read the 'repeated' (not recorded, realtime) Logic1 data, look for the periodic transmission bursts, convert the encoded waves to a binary character stream (ex: "0101001010") and print it to the screen (or log to file). Is this approach possible, in the way I'm thinking of it? Or is there an easier/better way to approach it? Also, I haven't been able to find many Script samples around the Logic# object. I understand it is similar to the Scope# (for example), but still a closer sample wound be great. Any tips/suggestions? Thanks -John
  2. Hello All, I see that the data acquisition toolkit( MATLAB ) supports the original Discovery module. Has anyone tried the Discovery 2 with Matlab ? I am debating weather or not to get the toolkit. Thanks !
  3. Hello All, We currently have the Discovery 2 in lab and use Waveforms to collect data. Is there anyway I can build a UI( think a simple form, name , value pairs ) into waveform to capture meta data while collection a sequence of scans ? I would like to embed the data into the scan file header or maybe in a txt file that I can write into the directory where the data is being written. Thanks so much for your help ! PS: I see that Matlab Supports the first version of the card, but nothing announced for version 2
  4. Hi Guys, im realatively new to electronics and even newer to measurements! I've just got my discovery 2 and was hoping someone might be able to guide me with some general question and tips. Sorry if my questions sound stupid in advance very new!!! Firstly, measuring balanced connections? I know what's required to measure single ended audio connections but trying to work out how best to measure seeing have inverting and non inverting connections plus gnd? Can anyone provide some guidance on how to go about this? Assume I know nothing when it comes to oscilloscope and waveforms!! secondly, measuring THD of an audio circuit has anyone got any tips of how best to measure, configure and calculate, using waveform? i assume it's something around using spectrum analyzer with test tone and looking at the harmonic against the fundamental, but some guidance on how to configure, measure and calculate would be awesome! lastly, what should be the expected noisefloor of the discovery be inheritly? -80ish db?? any guidance would be appreciated thanks guys hype
  5. Hi, I recently purchased the Discovery 2 and the BNC adapter board (Pro kit). Could someone please clarify where the positive and negative connectors for the scope should be attached when monitoring an AC signal (+/- 12 V). Should the negative connector be attached to the negative rail? And when using the BNC adapter board should the negative connector be connected to ground (because the inputs are not differential)? I wanted to confirm the connections as I had a mishap and toasted my pcb's power supply whilst trying to use the waveform generator and the oscilloscope. Just trying to debug why that happened. I had the oscilloscope's negative connector connected to ground.
  6. When I connect and select the Discovery 2, all I get is an error. Nothing else is connected to the Discovery 2, so it need not be drawing much current anyway. My Dell Inspiron 15R has potent USB ports. Discovery 1 can run from USB ports just fine...what the heck is the problem with this thing? And when I use a 5V 1300mA supply, I get the same error!? Please advise...
  7. I have just received a Discovery 2 and tried to download the waveforms 2015 software. On the site for the download I get redirected to and a message that firefox is unable to connect. Does anyone know of any other way to get these files? Does anyone else have trouble getting this download? Sean
  8. Analog Discovery 2 power supply

    Which external power supply is compatible with the Analog Discovery 2 to deliver 700mA of current? There are at least 2 power supplies in the Accessories section, but neither mentions compatibility with the Analog Discovery 2 kit. It would be nice if the webmaster could add this item under the "Related Products" section for the Analog Discovery 2, so it would be easier for people to find it. Thank you for your time.
