TDS3000C Series Oscilloscopes
Communications technicians must characterize
how well a communications signal complies with
international standards by determining if the signal’s
bits are accurately crossing the communications
channel. The TDS3000C Series allows these tech-
nicians to check the quality of a communications
signal using eye diagrams.
To use an eye diagram to check the quality
of a communications signal:
1. Press the front-panel
Autoset
button.
2. As desired, adjust the
Horizontal Scale
to adjust the
width of the eye.
3. Adjust the front-panel
Horizontal Delay
to view both
the positive and negative transitions at the same time.
