Barbouri's Electronics Projects
Restoring vintage electronics along with designing and building new circuits. One eye looking into the past, the other looking into the future.
I found a great deal on a Hewlett Packard 3314A 20 MHz function generator that was non-functional, but overall looked to be in good shape. It arrived in great condition and was well packed for a nice change. The seller clearly stated the issues with this unit such as errors when started up cold, which worsened over time until it finally lost the display and LED’s.
Cleanup and repair of a Hewlett Packard (HP) 8012B pulse generator purchased on Ebay as “Untested does not power on, sold as is”.
The 8012B was originally produced by the HP Gmbh Boeblingen Divison, Germany, but this later model was made in USA. It provides variable transition times down to 5 ns and the repetition rate can be adjusted from 1 Hz to 50 MHz.
This is a continuation of my Wien Bridge Oscillator module design project. It houses all the parts needed for a portable Ultra-Low THD dual-frequency sine wave generator.
