Timebase

Delay Acceptable Range TR Entry

200 ps/div 1 ns 980 ps to 1.02 ns 3-1

500 ps/div 1.5 ns 1.48 ns to 1.52 ns 3-2

500 ps/div 2 ns 1.98 ns to 2.02 ns 3-3

Larger delays are generated as counted delay. The performance is

guaranteed by the design and does not need to be verified.

For the 81134A repeat the test for the second channel.
