Typical Characteristics
This subsection contains tables that list the various typical characteristics that
describe TDS 800 Digitizing Oscilloscopes.
Typical characteristics are described in terms of typical or average
performance. Typical characteristics
are not warranted.
This subsection lists only typical characteristics. A list of warranted character-
istics starts on page 2-13.
