  1. Thanks for the advise, the resistive divider does work, but I guess from now on I'll have to try and avoid using such low input signals.
  2. Hello all, I am having some trouble with noise from the waveform generator on the electronics explorer board. I have made an op-amp, but the output is very noisy, I thought it was my circuit at first, but it seems the input signal itself is noisy. Noisy in, noisy out. If any of you know of a solution to this problem I would greatly appreciate it. I have attached images of the the oscilloscope readings as well as the inputs I am supplying to the circuit. Thank you for your time, - Micah
  3. 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 calculations check out. I designed the circuit in B2Spice, software simulations confirm my calculations. I build the circuit on the electronics explorer board and test with oscilloscope and network analyzer. Oscilloscope results are fairly normal (lower than the theoretical results, Network analyzer is not. Below I have attached images of all my info and I will summarize calculations at the end (although I really doubt the fault lies there) So gain in this case is calculated by Vo/Vi or -R2/R1 which in either case should at least get me 30db. If going with the oscilloscope output we have (1.6/.05)=32 V/V. And db=20*log10(32)=30.1 db. But alas, I get 20 db over and over. More to my dissatisfaction is a fellow student using an Analog Discovery 2 has made nearly the same circuit (only differences are the resistor values, but it has same ratio) with almost exactly the same results except the network analyses comes out correctly. Thank you so much for your time if you made this far, and I would greatly appreciate any ideas.
  4. Thanks @attila, Updating the driver by following your instructions worked splendidly!
  5. Hello, I recently purchased an EE board and I am having the issue attila listed. "6. In case you see Unknown Device, verify the Hardware IDs under Properties, Details tab. If this is USBVID_04B4&PID_8613... ask for USB EEPROM reprogramming application." Specifically my computer list the hardware ID's as: USB\VID_1443&PID_0007&REV_0000 USB\VID_1443&PID_0007 However in the waveform software I cannot locate the my board to ask for USB EEPROM; in fact, there is no electronics explorer board option available to select only the digital and analog discoveries. I have checked my Waveform software and it is the latest version of 2015 (3.6.8) Any advice would be appreciated. Thank you.
