With the communications module, you get a cut-down version of the software for free. I've been using it for over a year now and I really haven't any problems with it. You should note that the captured waveforms are at the same resolution as the displayed waveforms. With the full software, I believe that you can also control the action of the 'scope as well as upload/download pictures (and import/export them). The TDS-210 has been a great tool, which I highly recommend. myke >>probably my dream scope which is the Tek 210, it comes in a slimline >>package which I thought was neat, and it also said it could be hooked up >>via rs-232.
