The Tektronix 1240 Logic Analyzer is a portable, general-purpose digital design and troubleshooting tool. The 1240D card supports high-speed hardware analysis with nine acquisition channels @ 100Mhz (10ns) and 5 ns glitch detection." ==================================== The 1240 and 1241 are the HP1630/50 of Tek logic analyzers... Relatively easy to setup and use for a beginner, but they can go to "ridiculously complex" if you really want to. They have ROM cartridges that allow for mnemonic disassembly and state analysis of most processors. (Hmmm, I should probably make some "multigame" mnemonic cartridges since they're impossible to find for sale.) The 1240/1 also support serial ports, printer ports, etc. You can "program" the capture module to get the most use from the memory-- when doing video work recently I'd do things like have the Tek count occurrances on my "hblank" line (to get to a certain line on the screen), and then trigger and grab the data I wanted. You can do all sorts of "wait for this, then count this N times, then wait for this, then look for this, and then grab all the data" nesting and whatnot. If there's a weak point it's with the "capture pods". You need them 'cause there's circuitry onboard. They can be hard to find and expensive depending on where you buy from. And they have these little wire harnesses that plug into them too... The 1241 is basically a 1240 with a color display. (Well, kinda color. It's "RG" -- no "B".) You can configure them with different capture cards-- the most common configuration is probably a single 9-channel and an 18 channel card. Capture memory isn't very big-- only about 256/512 words depending on if glitch capture is on or not, but you can chain the memory from multiple capture cards to make longer traces.
