This Video looks at some of the more common transistors, and shows you how to test them easily with the “diode test function” of your DMM. The transistor in the intro picture isn’t so common, but it was kind of photogenic.
Trying the TDR ( Time Domain Reflectometer ) with different oscilloscopes. First, the old Tektronix 547 shows it’s stuff, then the TDS220 oscilloscope, soon after.
Find out how to determine the Impedance of your “random pieces” of coaxial cable.
Also see what shorts, opens, and barrel connectors look like on the oscilloscope with this TDR.
This Video explains how to find the Distance To Fault in or DTF, using a Time Domain Reflectometer or “TDR.” Use this to locate problems with your coax cable.
Some simple math to determine “VF” or Velocity Factor of coaxial cable using an oscilloscope, TDR, and measuring tape.
This is a simple avalanche type, TDR ( Time domain reflectometer ) which allows you to analyze many different issues with coaxial cable. This is the first video in a small series. I will also cover DTF, or “Distance To Fault,” how to determine Impedance, using this TDR to Continue reading “TDR” or Time Domain Reflectometer, build and use this circuit.
Tektronix Type 555 Dual Beam Oscilloscope with over 100 vacuum tubes. See if it works after all these years.
Take a peek at my personal lab and bench.
Black Box gets my modified car through Emissions Test “AirCare” with ease. See what’s inside and it’s function.
Nixie tube counter made by MONSANTO electronics. Detailed modification of the existing circuitry.
