It is a passive microwave/radio repeater. They were used as an economic way of getting around line of sight obstacles. I came across the information on these researching a way of passively linking ...
I am a little late to the discussion, but I think I can provide yet another perspective. I found my way to this community via searching advice on improving my schematic clarity and found Olin's $...
Background. I have a legacy battery system that is comprised of twenty-four 12V Li-ion battery modules (self-protected), enclosed in a shell with the charging connection provided as a common groun...
I have watched multiple teardowns of this module, it is, as you have guessed, a capacitor discharge resistor network. The smoothing capacitor in this module is 550+0.68+0.68 uF 430VDC rating. Peak ...
Olin has a great answer, I just wanted to add some of my personal experience. I only started laying out PCBs three years ago, and I use KiCad. KiCad got curved traces support in test version 5.99 o...
I've not seen them sold separately through distributors like Mouser and such, and have not seen any hand tools for these. I found this document and this video - it looks like the machines are semi-...
Olin's response covered everything I would do in your situation as well. If the problem doesn't follow the probes and doesn't go away, I wonder if due to only two A to D inside the scope, this is t...
Does your produced CPL file correspond to the Altium layout, or to what Eurocircuits Assembly Visualizer is showing? Open the CPL file in Excel and check. If the Altium output is wrong, I'd say ch...
One of the reasons to follow the advice of your instructor is that page 17 of the datasheet identifies the need for ground return paths for input bias currents. Your initial setup may or may not wo...
Do you supply the PSON# signal before or after the main power comes on, or before connecting the load? Looking at the datasheets, the correct sequence is VAC power on, then PSON# signal to ground,...
