Im looking on evil bay at a hp8116A function generator. The one I'm looking at is displaying an e52. I have looked all over for error codes and am not able to find anything. The manual from agilent tells me to look at section 10 but the manual ends at 9-27. I was hoping someone here has that function generator and the manual?

I have one.

1) get yourself a good copy of the service manual from Artekmanuals.com



2) Check all power supply rails for level and ripple.

3) There is a memory battery - check it and change it.

4) The error e-52 is Shaper IC 401 not able to supply negative output when...
see service blocks 5,6,7.

This may be a power supply issue if you are lucky.

The seller wants $175 I don't know if its worth the risk.

There are a couple on ebay for less and that seem to be working. This unit has a few hard to find IC's that might be the issue with the one with the self test error. I would stay away myself unless he would take $50 or less. But that is me.

According to the manual(s)? ( I have no personal experience working on this unit)? E52 error is most likely U401 Shaper IC is unable to supply negative output . U401 is listed as a custom HP IC IDC7 hp part number 1826-0923. U401 is further implicated if you are not getting Error E51. The block diagram of U401 would seem to point to the IC itself ( very busy little boy inside).? Could be the -15V rail too I suppose but I would expect other errors as well if that is off ??

As one poster noted better to take this over to the HP_Agilent_Group to find a real expert

I'm going to take your advise and stay away. My budget does not permit too many mistakes. Thank you all for your help.
