Hello,
I have more of a mechanical background so I was looking to get some help from someone with an electrical background with this. I am trying to use a BK Precision Function Generator (datasheet: https://bkpmedia.s3.amazonaws.com/downloads/manuals/en-us/4017A_manual.pdf) to send a signal to a Teensy 3.6 microcontroller at around 80kHz to see if it able to read and write an analog input at this frequency.
I have an Arduino sketch that will log the data to a microSD on the Teensy, but I am unsure about exactly how to hook everything up properly. I think that I will need to have a coax cable connected to the output of the function generator and then have it split so that I can connect to an analog input pin and ground pin on the Teensy, but I am concerned about the voltage output of the function generator. From what I can tell the pins on the Teensy are rated to 3.3 V and in the specifications of the function generator datasheet there are multiple output types listed, all with different voltages, and I am unsure which one pertains to my situation. One other possible issue is that the ADCs on the Teensy have a reference voltage of 1.2 V so does that mean I have to send the analog signal in at 1.2 V?
This is my first time using a function generator and I am hoping to not fry my board, so any advice on this would be greatly appreciated! Thanks in advance!
Greg
