Test equipment for storing wave forms.

[Dave]

I am having some problems with some equipment that communicates via
1553 communication standard. The communication is being corrupted and I
want to investigate the problem more. I would like to be able to log
an entire conversation between my equipment and look carefully at the
signal trace to see where it became corrupted. A conversation takes
between 2 and 20 minutes and the transmission frequency is around
60Khz. The signal amplitude is around 1 volt. Is there any reasonably
priced test equipment that would allow me to log all of this?

If you had said 20 kHz I would have said use a PC with a sound card. You
might ask around whether there are sound cards that can be tricked into
working as high as 60 kHz.

this doesn't sound like 1553 to me. I believe that the signal levels are
more like 12-25 vpp and the frequency around 1MHz. I could be wrong but
that is what I see in use. That being said there is plenty of equipment
designed for 1553 monitoring and troubleshooting; what do you consider a
reasonalbe price?

We refer to it as 1553, whether it is correct or not. It might be more
correct to say Manchester II biphase communication with the specs that
I gave. Our signals are at 60kHz, 1.2 vpp. A reasonable price would
be $2000, but the cheapest thing that will do a good job is what I need.

The Rule with wimmen, guns and instruments is: It's cheaper to rent
than it is to buy!

Ok, fair enough. I'm still wondering about what type of instrument
would work best for this. I've seen some PC based storage scopes that
look enticing, however the ones I've seen are only capable of storing
something like 50kSa/s and I really need 500kSa/s or more for at least
a few minutes (90 Mb @ 1 byte resolution) The PC based storage scopes
I have seen seem to be based on the slower parallel port and even if
they support USB, they aren't taking advantage of the speed. But then
I've not seen everything available I'm sure.

Perhaps a medium speed data acquisition board in a pc will do the job. Try
National Instruments and its competitors.
