O/E calibration modules boast dual wavelength measurement capability

With these new options, the MN4765B can be used with the MS4640B VectorStar Vector Network Analyser (VNA) family to perform optoelectronic measurements up to 70GHz at both 1310nm and 1550nm wavelengths.

Option 71 allows the MN4765B to be used with the VectorStar VNA to conduct optoelectronic measurements from 70kHz to 70GHz in the 1310nm range, while Option 72 provides measurements from 70kHz to 70GHz at both 1310nm and 1550nm to be made. Both options use a NIST-characterised photodiode as the primary standard, for greater E/O and O/E measurement accuracy when compared to alternative methods.

The MN4765B module, combined with the MS4640B VNA, provides a simplified approach for optoelectronic measurements and is an economical alternative to conventional total-system approaches currently used.

The optical modules are designed with an InGaAs photodiode that converts modulated optical signals to electrical signals. The photodiode has exceptional bandwidth response to 70GHz. Additional circuitry for temperature and bias stability are also incorporated into the modules.

With the new wavelength options, the MN4765B O/E calibration module can be used to conduct dual wavelength optoelectronic measurements to characterise components during R&D and manufacturing. It is also well suited for universities and research labs where modulation rates up to 70GHz at dual wavelengths are being explored.

VectorStar VNAs provide more accurate measurements over single-sweep frequency ranges of 70kHz to 20GHz, 40GHz, 50GHz, 70GHz, 110GHz, 145GHz and a variety of discrete bands to 1.1 THz. Unlike other VNA solutions on the market, the VectorStar family is built on a stable, modern platform that can be easily upgraded across a range of functionality and performance. T

The VNA series offers a high level of performance, so device modelling engineers can accurately and reliably characterise their devices. R&D engineers can achieve the last fraction of a dB out of their state-of-the-art designs and manufacturing engineers can maximise throughput without sacrificing accuracy.
