Complex modulation: optical modulation analyzer
At the extremes of electrical and optical measurements, the right oscilloscope will help
you explore the “what” and understand the “why” in …
Q-Series oscilloscopes are also
available in combination with the
N4391A optical modulation analyzer as
a fully specified turn-key instrument.
This compact solution offers the highest
bandwidth available on the market
and is the most advanced test solution
for advanced research on 400-G and
terabit transmission. Even for the lower
20-GHz bandwidth range, this compact
and easy-to-use solution is a reference
system for 100-G transmission required
by R&D labs working at 100 G and
beyond. By providing four channels of
33 GHz bandwidth, the Q-Series saves
you the expense of a second instrument
to analyze dual polarization.
If you prefer to operate with your own
optical receivers but want to benefit
from the enormous analysis capability,
you can get the N4391A’s analysis
software as a standalone package.
Features and benefits
