Agilent Debuts 6-GHz Signal Generators

May 1, 2012. Agilent Technologies Inc. has announced four new X-Series signal generators, including MXG and EXG models available in analog and vector versions. The new signal generators support the development of components and receivers that meet the challenges of mitigating interference, speeding data throughput, and increasing signal quality in applications such as radar, military communications, and consumer wireless applications.

While the moderately priced EXG employs a single-loop design, the MXG uses a triple-loop synthesizer to deliver phase noise performance of -146 dBc/Hz at 1 GHz and 20 kHz offset, enabling it to provide the pure and precise signals needed to test aerospace/defense enhanced radar designs. For developers of radar components such as mixers and analog-to-digital converters, the MXG also features spurious performance of -96 dBc at 1 GHz.

Agilent reports that for wireless communications, demand for more data and better coverage is driving higher performance in consumer devices and network infrastructure. For designers developing faster data streaming in 802.11ac devices, the MXG offers factory-equalized 160-MHz RF bandwidth and ±0.2 dB flatness. Both the MXG and EXG deliver low EVM, output power up to +27 dBm, and ACPR of up to -73 dBc.

To support a broad range of signals for cellular communications, wireless connectivity, video, and navigation, the MXG and EXG now provide real-time simulation of complex real-world signals. The associated Agilent Signal Studio software—a flexible suite of tools that accelerates signal creation—offers support for rapidly changing standards and highly complex signals such as real-time simulation of GPS or GLONASS constellations and performance testing of LTE base stations.

In manufacturing test, the cost-effective EXG is optimized for extended uptime and fast throughput (<900-µs switching). It also provides the signals needed for basic parametric testing of components and functional verification of receivers.

To reduce cost of ownership, the X-Series is designed for reliability and fast, easy calibration, service and repair. Today’s MXG and EXG leverage technology used in previous-generation MXG signal generators. The recommended three-year calibration cycle and self-maintenance strategy will help reduce support costs and increase instrument uptime.

“Our ongoing innovation in signal generation is driving the unsurpassed performance our customers need to test their highest performance devices,” said Andy Botka, vice president and general manager of Agilent’s Microwave and Communications Division. “With signals that range from simple to complex and pure to impaired, the MXG and EXG support detailed measurements that reveal the true performance of advanced designs.”

Price: from $6,900 for the EXG N5171B analog signal generator to $19,320 for the MXG N5182B vector signal generator. Agilent Technologies,
