A fast-switching microwave signal generator ideal for data intensive applications, such as antenna test, satellite payload test, and terrestrial microwave link testing, has been introduced by Anritsu Co. The MG37020A utilizes an advanced voltage-controlled oscillator (VCO)-based hardware architecture to achieve best-in-class frequency switching speed of 100?s per point.

The architecture integrates advanced RF hardware, enhanced computing, and digital interfaces that minimize command and trigger delays. The resulting switching speed is an order of magnitude faster than comparable YIG-based signal generators, and phase noise is maintained at a low -101dBc/Hz at 10kHz offset at 10GHz.

The MG37020A covers a frequency range of 10MHz to 20GHz in 0.001 Hz steps. It features +23dBm high output power at 20GHz, and high performance pulse modulation to conduct highly accurate signal simulation of pulsed signals. It uses a Windows XP Professional platform, has a color touch screen display and the ability to use a mouse and keyboard. The user interface has been optimized for ease of use with an intuitive menu flow, familiar icons and on-screen function keys. Enhanced connectivity with USB 2.0 Device and Host, Ethernet LAN, IEEE-488 GPIB and RS-232 Serial I/O are all standard. The variety of connectivity options and the MG37020A's low profile of 133mm 450mm further enhance the signal generator's ATE advantages.

Anritsu has developed options that address specific testing requirements. The MG37020A Pulse Modulation option includes pulse burst capability designed to address dynamic frequency selection (DFS) test applications. This option does away with external pulse generators, saving space and cost.

An Ultra-Stable Phase Track option is also available. When the option is installed, up to four MG37020A synthesizers can be interconnected, for those applications requiring multiple test signals that accurately phase track each other.

Anritsu's line of synthesized microwave signal generators covers the full range of R&D, manufacturing and maintenance applications in the microwave industries, including components and subsystems, satellite communications, aerospace/defense electronics, and university research.

Aside from applications mentioned above, the increased throughput and lower cost of test created by the fast switching speed also make the MG37020A excellent for high volume component manufacturing, such as RFIC and MMIC testing. The MG37020A has a delivery of 12 weeks ARO.
