Tektronix considers the THS3000s to be scopes rather than combination scopes/DMMs (digital multimeters), as in Fluke’s case. The Tek and Fluke user interfaces differ somewhat, and, in the single-channel mode, Tek’s top-of-the-line THS3024 takes twice as many samples per unit time—a maximum of 5G samples/sec—as does Fluke’s 190-II-204. Fluke and Tektronix also have different approaches to the software with which their customers are likely to use the instruments. Fluke’s base prices are a bit lower than Tek’s but Fluke charges extra for its FlukeView software. Tektronix includes its Open Choice software with the instruments, thereby reducing the price differential.
