Care and Feeding of the HP 6632b

6632B Mrclean

Care and Feeding of the HP 6632b, Todd writes –

Yesterday Narrat1ve got a new (sort of) bench power supply in the form of an eBayed HP 6632b! You can read what HP says about it but it basically kicks as much ass as I could really want or expect a single output PSU to kick. Until now I’d been using a couple of Tektronix PS503a units (which are pretty great, actually) and a Power Designs TW6050a (which is very heavy). However in the course of figuring out some VCO stuff I found myself really wanting to be able to step by small numbers of millivolts and trust with some certainty that what I was asking for was what I was getting (and the 6632b’s microamp measurement is handy for embedded stuff, too).

  1. Great PS….I have a couple in my metrology lab…

  2. Hi, I have also ebayed a 6632B ps. I like it too.
    Is it normal the device gets very hot (mostly on the top right, and and the bottom left) even when just running idle with no load ? How hot is yours after running for 2-3 hours ?

Sorry, the comment form is closed at this time.
