  1. Both the export data display in Waveforms and the exported CSV data are incomplete/garbled I am using the image save function as workaround , but then have to manually transfer to spreadsheet Using most current Waveforms, downloaded today. Haven't looked at analyser export function yet impedance data.csv
  2. Hello there!! I'm trying to do capacitance measurements over the time with a Analog Discovery 2 NI edition and save then, as the code on the image below. But now, I need to implement 2 things in this script, wich I would like to know if it is possible to. 1) Save the measurements acquired automatically in a file on the computer (like a .txt or anything like that) 2) Make the script change the frequency of the Impedance meter as it run ( for example, acquisition 0 to 4 runs in 10kHz and 5 to 9 runs in 5kHz) If it is possible, how could I implement that on my script ? Than
  3. Hi guys, love this product, wish I had it when I was back getting my EE degree, couple of questions I don't understand what activates the warning message for load resistor too high or too low? I haven't found the guidance for what it should be - is it supposed to be some percentage of the expected impedance range? Is it meant to be a current limit? I'm measuring a small RLC network and getting both "too high" and "too low" warnings at nearly the same frequency points (2-3 each) near resonance of the circuit. That's with a 10k ohm load resistor and a network impedance that runs fr
  4. Dear, Is it possible to build a custom graph by the Script tool? My intention is to construct a graph of the imaginary part versus the real part of the impedance. Thanks in advance for your attention. Cleber Borges
  5. Hello I want to purchase a PmodIA board for some impedance analysis on batteries. I was wondering if I could connect the Pmod IA to an arduino to carry out the testing. Thank-you
  6. Notes and questions on impedance function Observations 1) Impedance function/capability not listed on the AD2 Data sheet 2) AD2 data sheet shows only one channel voltmeter "Single channel voltmeter (AC, DC, ±25V) Network analyzer – Bode, Nyquist, Nichols transfer diagrams of a circuit. Range: 1Hz to 10MHz" Questions 3) Online manual for the impedance function does not cover use with the BNC adapter "Selectable AC and DC coupling to oscilloscope probes Selectable 50-ohm or 0-ohm output impedance on arbitrary waveform generator (AWG) chan
  7. Hello, I'm using the pattern generator with the output type set to open drain when the output is Z, measuring the output impedance I read almost 5K Ohm, What could be the problem?
  8. Hello to everyone. I recently purchased an pmodIA board for a project we are conducting at work. The main goal is to obtain some resistivity vs frequency spectra for different objects as part of a object characterization problem involving Oil/Gas stuff. I already read the guide that digilent guys provide (http://store.digilentinc.com/pmod-ia-impedance-analyzer/) and I found some C libraries for the AD5933 (https://github.com/analogdevicesinc/no-OS/blob/master/Pmods/PmodIA/AD5933.c and https://github.com/analogdevicesinc/no-OS/blob/master/drivers/AD5933/AD5933.c). I am using a Ra
  9. Hello, My question is about the output current of the AD2, AWG. I know the current Max. Output is 10mA, but, I can't find if that current is expressed in Irms or it is Ipeak. I need to know that, because I want to build a box with a potentiometer inside, in order to control the output amplitude in an analogic fashion, setting the AWG out (sinewave) to 10Vpp (5Vp or 3.53Vrms) and set the potentiometer to taste to achieve the voltage needed. Trying to figure out what potentiometer I should use, doing the math tells me that a 50ohm pot is way too low to load the AWG output, taki
  10. Hi all, I am Viviane working in impedance spectroscopy as my PhD research performing it in ionic solutions and cell solutions. I have a solution which is simply CaCl2 salt dissolved in water in the concentration of 0.4M and I am measuring the impedance spectrum of the setup using the equipment Gamry Interface 1000 in the frequency range 0.1 to 1MHz. I have done some measurements and got my results. My student worked in the measurements for one month and have done the same experiments as I did. When I compare the impedance measured in our results, in high frequency they are very simi
  11. Greetings, I need to know what is the output characteristic impedance of the VHDC connectors on the Genesys Virtex 5 FPGA Develpment Board. The datasheet only says they are impedance-controlled matched pairs and the schematic does not have this info. Some online forums said SCSI is defined by ANSI X3.13, the nominal diff cable impedance is 122 Ohms and I want to check if my board IO is consistent with this standard or not. I need to design a mating board to convert high speed differential signals into single ended, and signal integrity is a big deal. Thanks in advance,
  12. I'm an electrochemist wondering if I can use the Analog Discovery to do impedance spectroscopy. I've ordered one to try out, but it hasn't arrived yet so I'm playing around with WaveForms 2015 software. I am no electrical engineer, so I have lots of questions. The normal settings we use in electrochemical impedance spectroscopy (eis) are as follows: Frequency range: 0.01-10,000Hz (1-10,000 probably ok), single sine wave to probe system: amplitude 10mV, use Nyquist (real/imag impedance) and Bode (freq vs impedance/ohm) plots to analyze the system. There are other settings such as wait
  13. Please, I need informations about how to physically connect PModIA to the circuit for impedance measurement. Can someone send-me a schematics? Thanks.
