Inspired by Marco Reps video and a visit to the HPM7177 ADC documentation website, I ordered the Analog Devices AD7177 EVAL kit from Mouser. Just to see what fun could result. Attached are some photos and other output. Just to be clear: two days ago, all I knew about ADC of voltage was from working with an Arduino and various sensors.
The EVAL board can work on its own, but for an extra $100 there is a microprocessor that makes interfacing with the AD software trivial. So my total investment is under $200. The evaluation software is well documented and it will let you set the operational parameters by clicking on the virtual configuration panel. I had to do some research to learn the ADC jargon and the function of all the AVSS, AVDD, etc. (thank you internet). Being a NOOB myself, I will assume that readers will not benefit from my explanation other than to describe the setup as a unipolar input of 3VDC from an HP3245A source and that the AD7177 was configured as shown on two of the photos below.
