  1. BNC output configuration

    What type of application are you driving and what precision is needed? A simple inexpensive adapter/breakout board can convert the DIO to higher voltage/ currents in PWM Look at adafruit tb6612 PWM motor driver board , chip is good to 100 KHZ Output capability 4.5 -13.5 v and 1.2Amp
  2. Survey by Digilent

    I was expecting a pop up window with actual coupon, or an email confirmation. Something to save for later , since I need to accumulate products I want into a single order to offset freight. I didn't realize my error in not writing down the number until I closed the window Please email code to me privately Thanks
  3. Survey by Digilent

    Completed the survey , didn't realize that the discount offer message was only a number given at the bottom of the end of the survey. If not written down before closing survey , you are out of luck? Could have been clearer in the invitation to the survey. Maybe send out forum announcement?
  4. USB Isolation Not cheap, but looks good if professional application needs it I have been looking also, will reply again if I find one at an affordable price point
  5. The breadboard adapter would be convenient for some applications I have ,if the vertical connector for jumper wires was not present.Hardwired connections could be soldered to the through hole permanent breadboard area. 1) Can the board be purchased unpopulated, no connectors installed, no solderless breadboard ? 2) Would the board PCB files , less the artwork with the Digilent trademark, be available ? That would provide an easy start point to design custom interfaces , rather than start a board design from scratch.
  6. Adding one comment , if you only need short leads ( less than 12 inches) , you can buy premade jumpers in any combination of male/female ends. They are easy to remove the plastic housing so that you can re insert into the multipin Dgilent connector or any combo connector you want About 100 time faster and better job than stripping and crimping yourself by hand Can also get them in a rainbow colored ribbon cable or separable zip ribbon Amazon again has a lot of them , cheap.
  7. Digikey 609-3540-ND =Amphenol 65846 The tab is .062 wide instead of .130 on above unit Haven't ordered them yet, so not tested You have to have the pins/sockets and crimp tool Amazon has best deals ( Chinese) on those , look for "Dupont Connector" 65846.pdf
  8. AD2 or EE as ADC/ DAQ recording system

    I am only seeing a single16k sample buffer , so a very short time to fill buffer at max 100M samples rate. The logger function in the Scope GUI looks like it only dumps/ sends buffer to PC in CSV format , so some data overhead there and delay before next buffer sent? Overhead from scope GUI process? Output to PC is limited by USB2 So I don't see any way to get full sample rate data out except for one buffer fill? Question 1 :With GUI ,what sample logging rate can the AD2 accomplish as a stream, no breaks in data? Question 2: If I am using triggering to log samples , how to calculate max rate of triggers the AD2 can keep up with? Question 3:If I go into deeper into the system software either through AD2 SDK or Adept software , can I stream data faster from the digitized samples coming into the FPGA out to AD2 digital outputs, where I can pick them up with external DAQ card with digital input?
  9. With limited funds and learning curve time , trying to decide on system(s) to purchase. AD2 looks as if it suits me well for support instrumentation used for auxiliary circuit development .The software is well done and versatile The 100Ms scope sample rate and multiple device syncing lean me toward the AD2 ,but the EE is better for bread-boarding. I am not seeing much info/clarity in either the GUI interface, scripting or the SDK in using either board as a high rate DAQ. I don't want to get down to the level of the FPGA itself , looking for functional tools to make progress with other interests . If neither of these will support fast DAQ, then I will go with the EE for breadboarding and look elsewhere for seperate DAQ. I would like to stay in same product ecosytem, there are impossibly many options, so it looks like I need to pick a "side".
