When it comes to high speed storage oscilloscopes, the analog type often beats the price of many digital storage scopes. Consider the 7633 Storage Oscilloscope, a multi-mode storage mainframe which uses a wide variety of plug-ins including logic analyzers, spectrum analyzers, sampling scopes, and of course, oscilloscopes. This three compartment mainframe has a stored writing rate of 1000 cm/?s with display modes of Store, Nonstore, and Save. Store modes include bi-stable, variable persistence, fast bi-stable, and fast variable persistence. Plug-ins sold separately.
