81100 Family of Pulse/Pattern Generators
技術綜覽
This product note describes how R&D engineers in the communication industry use Keysight Technologies, Inc. pulse generators for the development of video interfaces for projection units. Several data communication companies develop interfaces between Local Clock Oscillators (LCOs) and video, TV, or computers for overhead projection units. It is very important for them to stay up-to-date with the rapidly changing video interfaces in computers, and to have test equipment that can simulate these different interfaces (such as HDTV interfaces). These interfaces vary from 33 MHz to 80 MHz.
A critical indicator of the quality of their design is its sensitivity to a jittering distributed clock signal, both in frequency and amplitude. Required equipment for Lab 2
– 1 x pulse/pattern generator
(81150A or 81160A)
– 1 x Infiniium oscilloscope
– 4 x BNC cables
How to hook up the instruments
– Connect strobe out 2 (pulse/pattern generator) to channel 3 (scope).
– Connect output 1 (pulse/ pattern generator) to channel 1 (scope).
– Connect output 2 (pulse/pattern generator) to channel 2 (scope).
– Connect trigger out 2 (pulse/pattern generator) to channel 4 (scope).
