  1. Hello, bloody beginner here, I was wondering if it is possible to measure and tune an RFID HF antenna with the Analog Discovery 2. The documentation for the network analyser says it tops out at 10Mhz. The RFID antenna is at 13.56Mhz. Is it still possible to measure the antenna with the Discovery 2? Any help and advise is welcome on where to get started. Cheers
  2. i am using network analyzer to obtain open loop transfer function. I am adding perturbation through ADC. my question is do adding though software add delay in the transfer function ? since it is open loop so why it would add a delay in the final model ?
  3. Hi, I would like to measure control loop gain of DC-DC converter using AD2 network analyzer. Is it possible to add a digital filter to input channels of AD2 and measure gain and phase shift after digital filtering?
  4. Hi, I use WaveForm 3.11.5 and I would like to be able to import a previously exported Scope FFT, Impedance Analyzer and Network Analyzer data. The exports work fine, and it's pretty good for working with other tools that can handle .csv. On the other hand, it would be great to have the ability to import these values later to compare them with the ones we are measuring. I could imagine it as a new reference type, so we could import even multiple files, name them and choose colors for them. What do you think, @attila? Regards, Andras
  5. Hello, Some days ago I installed the new Waveforms software to update from Waveforms 2015. I have found that when running a loopback to check the Network Analyzer, the signals going to both scope inputs, randomly, stop the data adquisition, resulting in a bad representation of the bode plot. It happens in a random fashion, and when it fails, happens at the beggining of the sequence. I tryied to reinstall an older version of Waveforms and it works flawlessly. Checking the latest version in other computers, it fails too. Best regards Albert
  6. I was wondering whether it is possible to use the second function generator while the first one is being used for the network analyzer tool. Here is the use case: I'm testing part of a class-D amplifier, in which the triangle wave to the comparator is generated by the second function generator of the Analog Discovery 2. I'd like to use the network analyzer interface to characterize the amplifier, while keeping a fixed triangle wave on channel 2. I realize that there is probably some way to write a script to do this, but it would be nice to have all the GUI of the network anal
  7. Hello, is it possible to sweep both channels of the Waveform Generator (W1 and W2) where W2 = - W1 (synchronized) and choose W1 for the transmission line relative to Channel2. I need this for the Bode plot of an op amp circuitry with a differential Input stage. Many thanks in advance, Nurseda
  8. I am using the network analyzer on the Analog Discovery 2, and have had two separate device failures occur. They have both happened at low frequencies (the start of the bode sweep). The maximum output voltage is in the range of 2-3V from the source device but a bad connection at the input can cause a transient spike that I presume reaches above the maximum allowed input causing the problem which essentially locks one of the traces at 25Vdc. There is no DC voltage present and the scope probes are AC coupled. I am reasonably sure that some sort of transient spike is causing this and I occ
  9. Although I flaunt here with other people's feathers it seemed to me a nice topic for the forum. I love practical examples for the Analog Discovery 2. I think this mix of old school technology with modern technology is fascinating, don't you think so? If you don't want this on the forum feel free to throw it off with confidence. Greetings, Hans
  10. Hello all, First of all thank you for clicking this post, and please if you are knowledgeable in the network analyzer functions read this if you have time. I am having some trouble with the gain reading of the network analyzer. I am currently a student with a simple project of designing an inverting op-amp with a gain of approximately 32 db (and no this is not me trying to get someone to do my project for me). As far as I can tell the network analyzer must be reading it wrong or I have some setting that is off. I will try to summarize: I designed the circuit by hand, hand calcul
  11. 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
  12. Not sure my following question was asked and answered. I would like to know is there a tracking bandpass filter employed in network analyzer to improve SNR?
  13. Hi - really like the capability of the Network Analyzer - is it possible to export data form a saved DWFBODEDATA file? The data shows up if I use HotTrack but the export is grayed out. So the data looks to be there, I just cannot save it. Is there a conversion (or can someone help convert) the binary dwfbodedata file to numerical values? PS - I *know* it should have been exported during the data acq process. But the dwfbodedata was only saved so I will either have to redo the test or find a way to get the data. ' THANKS in advance
