Re: 7704A, good deal?

There are many fine points to learn regarding the TDR use. I think the most valuable thing you can do at this point is to play with it. Presumably you have no pressing need for this and you can take your time familiarizing yourself with not only the controls, but the documentation and physics of what you're looking at. Go through the "First Time Operation" section of the manual. Review the Calibration section, study the schematics, but don't worry about knowing it all yet. Just get familiar with it. Maybe order a hardcopy from your favorite auction site?

Build up appropriate hardware - having good/proper accessories goes a long way toward making the equipment easier to use. Build different lengths of cable, see what effects they have. Look at waveforms with and without termination. Get to know what does what. I tested all my SMA and BNC connectors and discovered I had a batch of 75ohm T's, not 50ohm. Friggin' Amazon. Caveat emptor. But it's all qualitative at this point. Get a good feel for the qualitative stuff first. Have fun! Great find!

Raymond and Harvey, Yes I read about it being fragiles in that regard.? I do keep a 50¦¸ load on it when not in use.? And thanks to Raymond, now I do not forget to discharge the cables. I put some more pictures of the little 6-inch patch cable I made, along with some some traces. Info in the images description. /g/TekScopes/album?id=270997 I have not enough experience to know if this is even good or not so much. I¡¯m counting on all you guys to let me know. Regards, and MERRY CHRISTMAS TO ALL. Thanks |
