Anritsu Launches Test Solution for Domain-transfer Devices

3/17/2003 - Anritsu Company's Microwave Measurement Division introduces a test solution consisting of its Lightning Vector Network Analyzer (VNA), characterized photodiode standard, and laser source that provides an extremely cost-effective method to accurately characterize domain-transfer devices such as optical modulators, direct modulated lasers, integrated transmitters, photodiodes, and photo-receivers. The integration of the Lightning VNA, with frequency coverage up to 65 GHz, enables the configuration to accurately analyze devices used in 2.5 Gb/s, 10 Gb/s, and 40 Gb/s transmission systems, making the solution extremely flexible in addition to affordable.

The Lightning solution facilitates the measurement of electrical-to-optical (E/O) and optical-to-electrical (O/E) transfer function in terms of bandwidth, flatness, and phase linearity (group delay). When measuring E/O devices, response of the characterized photodiode is de-embedded from the overall VNA measurement of the E/O, O/E back-to-back configuration. When measuring O/E devices, the photodiode is used to characterize an E/O standard, and the response is then de-embedded in a similar fashion. The de-embedding software is internal to Lightning and provides full on-screen direction, which simplifies calibration and improves measurement throughput.

A 40 Gb/s photodiode standard is available from Anritsu as an accessory for use with this application. This photodiode is characterized to 65 GHz for both magnitude and phase and is traceable to a "golden" standard, characterized by NIST.

Accurate and repeatable measurements are assured because of Lightning's high stability reference. The VNA has frequency stability of <5x10-9 and frequency resolution of 1 Hz as a standard. Its sweep speeds of less than 2 ms/point are superior to competitive offerings as well.

The performance and flexibility of the Lightning VNA make it well suited for a number of other applications, in addition to E/O, O/E measurements, such as pulsed s-parameter measurements, rise time, and propagation delay measurements.

Delivery is 4 to 6 weeks.
