storage scope

6-34 — elektor june 1981 storage scope first catch your signal . Sometimes it is very useful, if not necessary, to be able to "freeze" very fast or very slow signals that are to be examined on an oscilloscope screen. For this the oscilloscope will have to be provided with a memory. The solution offered in this article is to use a standard oscilloscope and combine it with the digital memory of the logic analyser (described in last month"s issue of Elektor). Included is a circuit which converts the analogue signal into a digital counterpart which can then be stored in the memory. As mentioned last month, the logic analyser main board already caters for the storage scope addition. Technical specifications storage scope • input sensitivity: 100 mV/div. • memory: 256 x 8 bit • sampling time: — 25 ps ... 5 ms (internal clock) — long without limitations (external clock) • highest input frequency (component): 2 kHz * functions: — AC/DC — V/div. — V/variable — DC-shif...
