description
The new N4375D single-mode LCA is designed on the basis of the latest 5222A series
network analyzers with 2-port or 4-port configuration. It is also the best measurement
solution for 26.5 GHz electro-optical components, radio over optical fiber (RoF), and
aerospace and defense (A&D) electro-optical test applications.
The accuracy of N4375D can be traced back to international standards, and it provides
guaranteed technical indicators for sensitive electro-optical S-parameter measurement
in a complete solution. When used in conjunction with the N4691B electronic
calibration kit, you can perform setup tests as quickly as possible, thus focusing on
component development.
The new N4375D can replace the 8703A/B series as the industry standard, and provides a
specified modulation frequency up to 26.5 GHz at 1310 nm and 1550 nm signal source
wavelengths or various wavelengths of external light input.
Benefits
Highly repeatable and accurate measurement. Because the noise on the trace is very
low, more details of the S21 characteristics can be displayed.
It can be traced back to international standards to ensure that the measurement
results are comparable and not affected by the respective measuring instruments.
Calibrate and measure quickly and easily, supporting low cost of ownership.
