CONSUMER demand for wideband wireless capabilities, such as Internet connectivity, mobile communications and wireless digital entertainment, is driving the development of high-speed wireless devices and networks with rapidly changing technologies and standards.

To help design engineers address these challenges, Agilent has introduced new test products for wideband systems.

These latest Agilent products help accelerate the design innovation of high-speed wireless devices and networks.

Consumers have come to expect mobile phones, laptops, set-top boxes and other digital devices to provide a variety of wireless services:

* Mobile phones now provide wireless, multi-player gaming through wireless LANs (WLANs).

* Laptops are being used more frequently for wireless access to the Internet through WLAN capabilities.

* Home entertainment devices are connecting wirelessly for networking of audio and video components using ultrawideband (UWB) technology.

* Television programming is turning to digital video broadcast (DVB) format for clearer, high-definition picture quality.

This diversity of technologies creates new, complex challenges for design engineers testing the performance of wireless signals in numerous applications.

Agilent provides a full suite of products to meet these challenges, and most recently has announced products that address wideband system development specifically:

* The industry's only arbitrary waveform generator that simultaneously delivers 1.25 GS/s and 10 bits of vertical resolution for emerging communications systems, such as UWB.

Specifically for UWB, the Agilent N6031A arbitrary waveform generator enables engineers to rapidly create realistic Orthogonal Frequency Division Multiplexing (OFDM) UWB signals compliant with the Multiband OFDM Alliance (MBOA) standards proposal.

The newly enhanced advanced sequencer capability extends the effective size of the on-board memory by compressing the total memory required for repetitive waveforms.

This capability gives engineers the ability to generate new signals from existing waveforms, which enables long, complex signal sequences to be easily created from the finite on-board memory.

* The industry's first 14-bit, 40MHz bandwidth digitiser for Agilent's PSA Series spectrum analyzers and new wide bandwidth signal analysis capabilities, including WLAN, WiMAX, mobile WiMAX, DVB, ZigBee, APCO-25 and VDL.

Such capabilities enable designers of cellular and emerging digital communications, as well as radar, satellite, and defense systems to easily evaluate and troubleshoot existing and emerging wideband modulation formats.
