AGILENT Technologies has announced the availability of the Agilent MXG signal generators, which offer industry-best adjacent channel power ratio (ACPR) performance and switching speeds, coupled with simplified self-maintenance to maximise uptime.

These new analogue and vector signal generators are ideal for manufacturing teams producing components and receivers for communications systems.

The Agilent MXG signal generators feature an adjacent channel leakage ratio (ACLR) performance at -65dBc (-69dBc measured) for a 4-carrier 3GPP W-CDMA signal, and -71dBc (-76dBc measured) for a single-carrier signal.

This performance allows for greater test margins, ensuring more accurate measurements and improved yield, and also makes the Agilent MXG signal generators suitable for characterising high dynamic-range components such as multi-carrier power amplifiers (MCPAs).

Agilent MXG signal generators also provide the fastest switching speeds, enabling a dramatic increase in throughput. With SCPI programming, the generators can make arbitrary switches in frequency and amplitude at =1.2ms.

In list mode, simultaneous switching of frequency, amplitude and waveforms takes place at =900µs.

Simplified self-maintenance is another key feature of the MXG generators, making it possible for all users to maintain or repair the instruments in-house and maximise uptime.

Typical onsite calibration can be performed in less than one hour and requires only a spectrum analyser and power meter. With 100-percent internal diagnostic capability and a simple design consisting of five assemblies including the single RF assembly (all are field-replaceable), the average Agilent MXG repair time is just 30 minutes with no calibration required.

The Agilent MXG analogue signal generator provides accurate and repeatable reference signals for applications like LO and clock substitution, CW interferers, and modulated signals for analogue communication systems such as AM, FM, and FM.

In comparison, the Agilent MXG vector signal generator provides the vector-modulated signals necessary to produce components for cellular communications and wireless connectivity systems.

The Agilent MXG vector signal generator works with Agilent's Signal Studio software to simplify standard-based waveform creation. Signal Studio's 3GPP W-CDMA software includes the latest revisions for HSUPA and HSDPA.

Its mobile WiMAX software complies with the latest revision to the IEEE 802.16e-2005 standard. Other standards-based Signal Studio software supported includes cdma2000/1xEV-DO, GSM/EDGE, TD-SCDMA and 802.11 WLAN.

Agilent's new MXG signal generators are ideally suited for use in high-volume wireless component manufacturing, as well as in high-performance, base station MCPA (multi-carrier power amplifier) design and low-volume manufacturing.

With a cost-effective price point and an option structure that provides scalable performance, the Agilent MXG signal generators are also suitable for design and manufacturing WiMAX and WLAN receivers for the cost-sensitive wireless connectivity industry.

The Agilent MXG signal generators are fully compliant with the LXI class-C specification and are part of the Agilent Open program, which simplifies test-system setup and integration by offering instruments based on open industry standards.

Agilent MXG connectivity is possible via 100 based-T LAN, GPIB and two USB 2.0 ports. LXI is the next-generation, LAN-based modular architecture standard for automated test systems.
