These have been around for awhile

The biggest one is this:

If anyone else has any others, I'd be interested.

Probably because you're using Google Groups [spit], and it looks like it's
trimming the URL. It's 31MB, so it would be best to download yourself.

Go to www.ko4bb.com and navigate your way - Manuals, Tektronix,
Tektronix_-_Miscelaneous. The file is named Tektronix_Xref_sm.

I sent Bob email with the correct links, untrimmed, for both cross
references.

is ok. when the 'redirect to ..." sentence came up, just before it
would disappear, I ctrl-c'd it onto Notepad, corrected it to a
reasonable looking URL, and tried again. That worked! Took from 8:14
to 10:43 to get it downloaded using dial up. But it IS a wealth of
information. Thank you for posting!

Default TEK 2712 repair info


OK, seems like a good place to ask this question...

I have a Tek 2712 spectrum analyzer and one of the Philips PLS157 PLA is
bad. It is in the trace blanking logic. I can buy an unprogrammed PLS157
on E-bay.

Anybody have any ideas where I can get the program info or even better a
pre-programmed part. It is A9U308 PN 160-5005-00 Man code 8009 which is
TEK .

Or failing that, anybody have an idea of what the logic is that is used to
create the blanking signal, there are about 4 or 5 inputs to this chip and
only one output is bad so I might be able to wire up some combinational
logic to re-create the function.

If anybody out there has any info about this, I could use it.

TIA

Mark

Mark,

You might try searching the following Yahoo forums:

http://tech.groups.yahoo.com/group/TekScopes/
http://tech.groups.yahoo.com/group/TekScopes2/

The first one gave 59 hits on "2712 spectrum analyzer", and the second
gave 2 that were of no interest.

But you might find someone who has more information on what you are
looking for. I'm sure if the information exists, they can help you find
it.

Mike

Any way you can disconnect the output and look for glitches when
it should switch? work the logic backwards.

Blanking shouldn't be too hard to figure out??

Don't know anything about the chip...assume it'd read locked so you can't
get out the contents???

I've fixed a 308 logic analyzer with a bad prom. Wouldn't run at
speed, but worked well enough to read out the bits.

The logic is quite simple. I have some PDFs with diagrams created by
other people. The PLS157 dies often in these spectrum analyzers.

If you register with this site you can download the PDFs (otherwise
they are invisible):
