Bwahahahaha. That tidbit is kind of common knowledge around here (s.e.d). For some real interesting times go really hunting for fast analog scopes, they are available, though not inexpensive. 500 MHz is still reasonably available, for about the price of a modest car.

That is intriguing! Sounds like the new owners might be more focused on all this wireless stuff than the old ones, though, which could be beneficial. The new guys provided the wireless intercom systems that I used some twenty-some-odd years ago as McDonalds burger flipper; they must be doing something right to still be around, I expect. > I don't like the opposite either; no specs - wing it.

"See, you changed the project spec last Monday, and the Tuesday before that, and then again yesterday afternoon, and..." :-) ---Joel

Tek 7103s and 7104s, 1 GHz analog scopes with microchannel plate CRTs, are fairly cheap on the used market. An 11801 sampler with a 12 GHz head can be had for under $2K. Nice scopes. John |
