The '''Tektronix TDS784''' is a 1 GHz, 4 GS/s quad-channel digital storage scope. | The '''Tektronix TDS784''' is a 1 GHz, 4 GS/s quad-channel digital storage scope. | ||
There | There are four variants, all with the same specs but different hardware/software loads: TDS784A, B, C & D. Of these, the C and D models are the least problematic and most sought-after. | ||
For units with serial numbers prior to B04xxxx, the latest known firmware revision is 6.6e. For units with serial numbers B04xxxx and above, the last known version is 7.4e. Note that, due to differences in acquisition and CPU board hardware, release 7.4e will not work in the earlier revision units. Early revision units may have a CPU board P/N of 679-4172-00. The later revision is 679-4349-00. | |||
It is also worth noting the TDS754 and TDS784 series are nearly identical, with the differences being in front-panel cosmetics and the presence (754) or absence (784) of a few capacitors on the acquisition board. The only other difference is the position of instrument ID jumpers, also on the acquisition board. In fact, it is entirely possible to convert a 754 to a 784 (see the 'Links' section). | |||
Also, Simmconn Labs has developed a color LCD panel kit to replace the CRT display in most of the TDS series which use CRTs. Again, see the 'Links' section. | |||
