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 3551A Transmission Test Set

Checking out a HP 3551A sold as “For parts or not work­ing, will not pow­er on”, that I actu­al­ly pur­chased for parts.
My orig­i­nal intent on pur­chas­ing this unit was to sal­vage the knobs and con­nec­tors for repair­ing some of my oth­er HP gear. I did man­age to swap out four of the knobs before my curios­i­ty got the bet­ter of me.

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.

HP 5300B Counter Plug-On modules

Cleaning up and look­ing at a bunch of plug-on mod­ules for my Hewlett Packard 5300B main­frame mod­ules, after pur­chas­ing a new unit. It seems that I am start­ing to col­lect quite the range of mod­ules for my HP 5300 sys­tems since my orig­i­nal 5300B Measuring System back in 2017.

HP 34740A display and 34702A Multimeter Modules

As men­tioned in a pre­vi­ous post on the Hewlett Packard 34702A Multimeter mod­ule, I have been look­ing for a 34740A dis­play mod­ule to pair with it. I was lucky to find a mod­ule that was in a good cos­met­ic con­di­tion and untest­ed for a rea­son­able price.
