Anritsu upgrades VectorStar VNA O/E calibration modules

Test and measurement technology supplier Anritsu Co. says it has improved its MN4765B series of O/E calibration modules. Two new options for the series enable the MN4765B to be used with the MS4640B VectorStar Vector Network Analyzer (VNA) line to perform optoelectronic measurements up to 70 GHz at both 1310 nm and 1550 nm. The result is a highly accurate, flexible, and cost-effective approach for optoelectronic device characterization, including modulators, photoreceivers, and integrated optical transceiver modules, Anritsu asserts.

Option 71 sees the MS4765B operate from 70 kHz to 70 GHz in the 1310-nm range, while Option 72 supports measurements from 70 kHz to 70 GHz at both 1310 nm and 1550 nm. Both options use a NIST-characterized photodiode as the primary standard, Anritsu points out.

The new options enable technicians to use the MN4765B O/E calibration module to perform dual-wavelength optoelectronic measurements to characterize components during R&D and manufacturing. Anritsu also expects the options to make use of the module popular in universities and research labs exploring modulation rates up to 70 GHz at dual wavelengths.

The MN4765B module in combination with the MS4640B VNA offers a simplified more economical alternative to conventional total-system approaches, Anritsu says. The MN4765B optical modules are designed with an InGaAs photodiode that converts modulated optical signals to electrical signals. The photodiode offers bandwidth response to 70 GHz. The modules also feature additional circuitry for temperature and bias stability.

Anritsu designed the VectorStar VNAs to provide accurate measurements over single-sweep frequency ranges of 70 kHz to 20 GHz, 40 GHz, 50 GHz, 70 GHz, 110 GHz, 145 GHz, and a variety of discrete bands to 1.1 THz.
