The Tektronix CSA803 is a digital sampling oscilloscope that takes two 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.
