I've made a bit of an oops here. There are three different things that can be plugged on the back of the TDS-210/220. The TDS2HM is a hard copy module. That is a centronix port that allows direct output to a printer only. The TDS2CM is a comms module. Centronix, RS232 & GPIB. Comes with Wavestar Lite and costs around $260. The TDS2MM is the measurement module which is the same as the TDS2CM plus it adds the extra measurement features (rise/fall, pulse width & FFT). That costs around $500. My understanding was that the CM had evolved into the MM, but that obviously isn't the case. Sorry for any confusion. Steve. ====================================================== Very funny Scotty.
