The '''Tektronix CSA803''' is a digital sampling oscilloscope that takes two [[:Category:11800 series sampling plugins|11800 series plug-in sampling modules]]. | |||
The two left plug-in slots are supplying DC only and are supposed to be used for optical to electrical converters like the [[SD-48]]. | |||
From the specifications of the CSA803C and the [[11801C]] it seems that they are identical, except for omitting the two left plug-ins and adding the trigger ×10 prescaler function in the CSA803. | |||
