The Anritsu MG3700A is a vector signal generator built around a 160-MHz arbitrary waveform generator, combining a wide vector modulation bandwidth with large-capacity baseband memory. It generates digital modulation signals across a broad range of wireless systems, supporting evaluation of general-purpose mobile communications such as mobile phones as well as wireless LANs.

A vector signal generator produces controllable, modulated RF stimulus signals used to exercise a device under test so its response can be measured. The MG3700A is applied to evaluating receiver characteristics of base stations and UEs across various mobile communications systems, to testing multi-mode wireless devices that support several technologies at once, and to research and development of evolving communication systems. Its waveform combining function lets a single unit output a wanted signal together with an interfering signal or with AWGN for measurements such as Adjacent Channel Selectivity (ACS) and blocking characteristics.

ValueTronics International stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit we sell is inspected and functionally verified in-house by our technicians before it ships, while new units ship factory-sealed exactly as received from the manufacturer, so you can buy with confidence whichever condition fits your budget and application.
