HP 3314A Function Generator Repair

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.

Hewlett Packard 8012B Pulse Generator

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.
