  • I once worked in Tek for a very short period. I got to experience the 2235 and 2465 analog scopes and their controls. The 2465 was a 400 MHz Digitally Controlled Analog Scope. I also used the Plugin System Scopes and Calibration systems; these were Tek…
  • Small Boards, SMT circuits and hybrid electronics need special tools. The soldering and handling require some tools and custom jigs which can be custom designed.  Some product are mass produced, some tools for managing and working on Tiny PCB's…
  • If you have made an electronic product with a new circuit or code and need to protect it, then these are some Methods. If your Intellectual Property is an Idea, A Hardware Innovation or Software Application; It may need some protection other than…
  • Most of the sensor interface and instrument inputs are analog; even if it event based like a limit switch, analog circuit protection and signal conditioning is required before it reaches the level sensitive digital circuit blocks. Starting with Schmitt…
  • Here are circuits made of Resistors, Capacitors and Inductors which are passive components. Crystals, Thermistors, Varistors, Variable Passive RLC are also Passive Parts.Some circuits documented from my design note book.
  • delabs designed and built many custom "engineered" Test Instruments. They were not prefect, as only one or two were fabricated. That means it will be costly to produce such instruments. It is just like tooling, you have to make some numbers to recover…
