DL0100A1 vs RS8 vs RS104: Comparison

These two 8-Channel and 1 4-Channel ultrasonic (UT) pulser-receivers for non-destructive testing (NDT) boards share several characteristics and also target very different use-cases. That is, each is optimized for different applications.

This is a quick post, just to begin by showing the correct connector orientations for firmware updates. For some background on hardware and tools for developing (including just updating) firmware, please also see: https://oshablue.com/bsides/2020/01/18/hdl-0108-rscpt-materials-for-getting-started/

Ideas for Bug Reporting

Everybody’s time and efforts are valuable. With just a couple moments of extra time to flesh out some details regarding a bug report, usability issue, or even a feature request, you’ll get results much faster, and help keep the project humming along. It’s understood that you might not always have time to do so. Just …

ADMM-CP (VOM): R41 and High Source Impedance

Under conditions of very high source impedance or conditions that create a ground loop (other conditions apply as well), you may want to try removing R41 from the ADMM-CP (VOM) board (or testing with a board that doesn’t have it installed); if, after firmware updates and confirmation of measurement protocol, measurement values still seem inaccurate, …

ADMM-CP (VOM): Attenuated Mode

What it does The attenuated mode takes a real input voltage in the range of around +/- 14VDC and divides it down by about a factor of 10 so that it fits within the on-board ADC’s measurable voltage range of about +/- 1.4VDC. This is nominally and roughly. In a more detailed look, you might …
