HP / Keysight / Agilent N4375B - Network Analyzers

Lightwave Component Analyzer Software Version 2.3

The Lightwave Component Analyzer offers accurate and fast testing of electro-optical components for S21 responsivity, as well as electrical reflection.

The N4375B turnkey solution is based on Agilent PNA-L or PNA-X series network analyzers.

All system components are optimized for best overall performance, resulting in highest accuracy and lowest ripple.

The new N4375B replaces the industry standard 8703A/B series and supports modulation frequencies up to 26.5 GHz at 1310nm and 1550nm source wavelength.

Benefits

• Highly repeatable and accurate measurements show more details of S21 characteristicsdue to low noise on trace.
• Traceability to international standards ensures comparable measurement results independent of the individual instrument.
• Low cost of ownership supported by easy and fast calibration and measurement.

Features

• Absolute responsivity specification traceable to international standards
• NIST traceable relative frequency responsivity specification
• External optical source input for test at all wavelength between 1300 and 1600 nm
• System calibration up to 20 GHz with PNA-L, 26.5 GHz with PNA-X
• Fast and accurate calibration with electrical calibration module
• Extended calibration support for advanced test setup
• Built-in optical power meter
• User-selectable transmitter power
