Need a compact Optical Modulation Analyzer? Compact Integration of a digitizer, optics and analysis PC leads to a compact turn-key instrument. It also avoids any external cabling, making the instrument robust and easy to set up wherever needed. Despite the smaller size, the new N4392A offers a big laptop-size screen, giving you more insight in your signal for understanding and debugging your signals even faster. Portable The integration in a compact mid-size oscilloscope housing results in a lightweight instrument, which can be easily moved to any location in a lab or on the manufacturing...

4. LO input In experiments where an extremely stable local oscillator with linewidth in the low kHz range is required, this input can be used as local oscillator (LO) input for external lasers. (Option 320) 1. Vector signal analysis Like the N4391A, the N4392A is based on the Agilent 89601B vector signal analysis software which is extended for optical requirements. One software platform ensures exchangeability of setting files and measurement results between R&D and manufacturing. This also makes results comparable and exchangeable. 5. LO output Get part of the local oscillator signal to...

N4392A Transmitter Test in Manufacturing Optical constellation diagram In a constellation diagram, signal information is shown only at the middle of a symbol time. This represents exactly the time stamp a real receiver will take to decide on the transmitted data. These points are commonly referred to as detec- tion decision-points-, and are interpreted as the digital symbols. Constellation diagrams help identify effects like amplitude imbalance, quadrature error, or phase noise just to mention some of them. For calculating the BER based on statistical data a Gaussian noise distortion is...

N4392A Advanced Research on OFDM Guj'd Lorrtr Subumtts OFDM Astern SimpltFiiqutn^ : forma: Drljib lummnwr Anttnnrji Customer configurable generic OFDM demodulator OFDM is a very complex modulation scheme as it distributes the information not only over time with sequential vectors but also over frequency via a customiz- able number of subcarriers. Each subcarrier can have a different modulation format. In addition in most cases pilot tones need to be detected for synchroni- zation. With this custom configurable OFDM decoder nearly every variation of a digital ODFM signal can be set up and...

N4392A Integrated Coherent Receiver (ICR) Test Intradyne integrated coherent receiver test For detection of complex modulated optical signals OIF defined an electrooptical component typically described as Integrated Dual Polarization intradyne coherent receiver (ICR). This component contains optical and electo-optical components in one package, as shown in figure 18 as device under test. The hybrid contains many components that need to be integrated and perform seamless as a black box coherent receiver. The integrated component needs to be tested in research and in manufacturing. Figure 16....
