Atten AT6011 Died...
« on: June 17, 2015, 12:01:19 am »
I've had my AT6011 for a couple years, and the other day while taking a measurement it just flat blinked out... totally dark, no signs of life... i've opened the case and i dont see any blown fuses or obvious death signs, i was wondering if anybody has a line on any kind of schematics or service manual for this "One-Hung-Lo" basic Spec-An. Would sure like to get her back up and running i have some stuff to use it for, and not really the spare cash to drop on a new equivelent.

Thanks Everyone

- Mike

Probably a PSU failure, is it a SMPS?
Is the PSU on a seperate PCB?
Have you checked for any voltages?

Have you emailed Atten? Just email sales, they have been quite helpful for me when needed.
I'm not sure if they offer a 3 year warranty like Siglent.  :-//
They'll need to know the SN.

I'd be checking all this out and maybe contact them for a replacement PSU if you don't have the gear or skills to fix it.

I am not 100% sure but were'nt these Atten Spectrum analyzer clones of older Hameg Spectrum Analyzer?
Maybe you can find some Hameg docs easier.

It looks like a rebadged (?) Hameg spectrum analyzer.

At least it is inspired by some Hameg spectrum analyzers.

sorry to drag this back up..
any outcome ???

just bought one via eBay for a few quid.
worked great for an hour or two,
went on the tracking generator, worked once.
tried something else, went back to TG and the LCD display faded, screen went off.
switched off and the unit came back on, s soon as TG is switched on fade and well..

did this a load of times..

checked inside.
found some poor soldering,
well lots.
a dodgy transistor and wire.
and a bit of enabled wire from the power socket (front panel board) to the TG switch.
i was thinking maybe this was chafing on the screw of something.
moved it so it touches nothing.
reflowed some solder as it was bad, tidied it up a  bit.
but all i get now is a faded LCD and no main screen..

i can't find a service manual any where,
contacted Atten but nothing yet.
also mines only three years old 2017 board print.

looking at maybe the voltage regulator but need voltages to compare.
any one ????

thanks...

Hi. Did you fix it? I have fixed the very similar problem on mine.
