Re: Clock error on TDS3034
" I recently bought a nice TDS3034.
Unfortunately, its clock has a problem: I may set date and time but it does
not keep it, not even without a restart. "
Hello Raymond. I found a Dallas DRAM from some place in Florida that
someone on here recommended (it may have been on the EEVBLOG forum. I know
that's not much help. But once replaced, the scope booted all weird and
wouldn't boot. I needed to hold in the "B TRIG" button while powering-up
to reset the scope.
With my nearly dead DRAM, not only did it loose time, it also could not
remember the GPIB address, it kept resetting to "0".
Do not buy the DALLAS DRAM on EBAY from China. They send you a fake chip
Okay, I think I found it. I think I bought the DALLAS DRAM chip from:
NAC Group, Inc. dba NAC Semi <http://www.nacsemi.com/>http://www.nacsemi.com
I got lucky and go a chip with some battery life left in. When I replace
it, I solder lead carriers in to the board. They were short enough that
the chip could get installed and have room (with may 1/4" to spare) for the
I/O module cage when re-assembling. I paid $38.99 for the chip.
