HP 5335A Timer / Counter - Anything i should know?
<< < (14/34) > >>

Dear,

Recently I won a 5335a from ebay. I've tested inputs A & B and seems ok.

It's a unit from 1982, I know it by the date of the IC's because the serial prefix has been deleted for someone in the past :(
Also, the unit has 4 sticks saying "Option 010, 020, 030 & 040". Looking outside & inside I see the OXCO & the cards for the  Voltmeter & Input C but I can not see the 040 opt. I need to study the manual to discover it because I do not find anything commented on this thread.

 a pictures of the unit & I have a question:

Who is lying, the 33210A or the 5335A? :-DD :-// (there is a continuous offset of 1,2ppm on frequency measurements)
Vgkid:
Option 40 is installed. Notice how many more triggering/input buttons are installed compared to the non opt 40 units

I've enjoyed having my 8335. 

One question though, when the inevitable tantalum failures happen, are you replacing with axial tantaliums or other?

Ive not managed to find a suitable source for these components.

Vgkid:
I dont think that the axial tants are of the wet slug variety, so you can replce them with uprated radial ones.
Vgkid:
Does anyone have the size of the back power input connector, or are they almost universal for a given style. I nitifed that my frequency jumps have started appearing again.
