0.00 An introduction with Marcel Zeiler
0.24 Demonstration of the required setup
1.00 Setting the frequency settings
2.02 Calibrating the network analyzer
2.44 A deeper look into the connections of the required setup
3.02 How to generate the electro-optical transmission measurement data
Learn how to measure the 3-dB cut-off frequency of an optical transmitter with the Keysight N4377A lightwave detector.
The N4377A Lightwave Detector is a self-contained, USB-powered optical-electrical converter with built-in optical power meter capability. With amplitude and phase response calibration data stored on board the device, vector network analyzers (such as PNA, PNA-X) can de-embed the converter from optical transmitter or modulator measurements, enabling accurate S21-parameter measurements in the photonic domain. Electrical spectrum analyzers benefit from the converter’s low intrinsic noise and high bandwidth when performing laser linewidth and modulation spectrum measurements.
