'[EE] DIY Tektronix RS232 module?'

       I would like to build a RS232 interface to my TDS220 scope.
       Tektronix has the TDS2CM modules, but at ridiculous prices!
       Is there some schematics available?

The only schematics would be in a Tek service manual, and that would
probably cost as much as the serial module.

I think you will find that there is quite a bit in the serial module, as in
more than just a UART. They do seem to put some smarts in there to handle
handshaking and the like, without loading down the main processor. It may
even have enough processing power to handle the command structure that is
used when connecting to labview and other similar control programs, again
without burdening the main processor with the overhead, and development cost
of the software.

When you find one come back and tell me :-)

I decided not to buy the module when I bought my Tek.
AFAIR it also does GPIB. I see this more as an attempt to justify the price
than the need to roll the two together.

If you have a TDS2000 series, then you are better off getting the module
with serial and compact flash. Unfortunately it does not work with the
TDS200 series, although the TDS200 series comms module works in a TDS2000
series.

IIRC, the module for the TDS200 series scopes also adds FFT
capability.  That may make it worth having as well.

Check secondhand retailers and maybe Ebay.  Good luck!

IIRC, the FFT is a seperate module from the RS232 module.
So, it is not worth the $$$$.
