Picosecond Pulse Labs 6110D teardown

 | |||||

 Stripping wire is a delight with the HOTweezers thermal wire stripper. I got two in the local salvage yards.  Thermal strippers melt the insulation and will not nick the copper wire. I first saw them used in at a military contractor that made satellites and jet avionics.  Opening the cover shows a mix of point-to-point wiring a a PCB (printed circuit board). |

 The output is an SMA connector as befits a high-speed pulse. The pulses are slow, but with sharp edges, the Fourier components are fast.  Fitting the mini-DIN input connector.  A fully-equipped lab evaluates the modules. |

 A machinists headband magnifier helps you see the parts.  The scope is triggered by input pulse generator.  This HP 8082A pulse generator feeds the Picosecond pulse generator. |

 The first unit works fine.  The second unit also works.  The third unit is bad, the waveform is not tightly driven. |

 . Here is a good one opened up, with the bad unit right above it. You can see the SMA cable from the unit to the scope. I have sinse stopped using right-anlge SMA cables, since they usualy have more impednce anomiliew that a simple straight cable. Files |
