Keysight (Agilent) N4375B

Keysight (Agilent) N4375B Lightwave Component Analyzer Description: Agilents N4375B Lightwave Component Analyzer (LCA) is the instrument of choice to test 10G Ethernet, FCx8, FCx10 and FCx16 electro-optical components, with up to 20 or 26.5 GHz modulation range. Modern optical transmission systems require fast, accurate and repeatable characterization of the core electro-optical components, the transmitter, receiver, and their subcomponents (lasers, modulators and detectors), to guarantee performance with respect to modulation bandwidth, jitter, gain, and distortion of the final transceiver. For frequency dependent responsivity measurements the N4375B is the successor of the industry standard 8703A/B LCAs. With a completely new design of the optical test set and a new RF-switched architecture, together with the latest PNA family of network analyzers, the N4375B guarantees excellent electro-optical measurement performance. In addition a unique new calibration concept significantly reduces time from powering up the LCA until the first calibrated measurement can be made. This increases productivity in R+D and on the manufacturing floor. The fully integrated turnkey solution reduces time to market, compared to the time-consuming development of a self-made setup. By optimizing the electrical and optical design of the N4375B for lowest noise and ripple, the accuracy has been improved by more than a factor of 3 and is now independent of the electrical reflection coefficient of the device under test. Its the excellent accuracy that improves the yield from tests performed with the N4375B, by narrowing margins needed to pass the tested devices. NIST traceability ensures world-wide comparability of test results. The advanced optical design together with temperature-stabilized transmitter and receiver ensures repeatable measurements over days without recalibration. Using the advanced measurement capabilities of the network analyzer, all S-parameter related characteristics of the device under test, like responsivity, ripple, group delay and 3 dB-cutoff frequency, can be qualified with the new N4375B Lightwave Component Analyzer from 10 MHz to 20 GHz. The N4375B comes in two basic versions. The economic line is based on a PNA-L network-analyzer and is available as a 2 port system. The high end version is based on the new PNA-X and offers true balanced measurements, extended optical modulation index (OMI) and is available with 2 or 4 ports. Both versions have the same specifications up to 20 GHz. The PNA-X based LCA is calibrated up to 26.5 GHz.
