Agilent Technologies Introduces First Microwave Signal Generator to Provide Vector Modulation up to 20 GHz in a Single Instrument

9/25/2002 - Agilent Technologies introduced the industry's first microwave signal generator to provide vector modulation up to 20 GHz in a single, integrated instrument.

The new Agilent E8267C Vector Signal Generator, a member of Agilent's next-generation Performance Signal Generator (PSG) series, features an I/Q modulation capability and internal baseband generator that enables the simulation of wideband complex waveforms for a variety of microwave applications. Other models in this new series include the Agilent E8257C Analog Signal Generator and the Agilent E8247C CW Signal Generator, which feature analog ramp sweep capability for use with the Agilent 8757D Scalar Network Analyzer.

Intended for aerospace and defense design and manufacturing engineers, the Agilent E8267C is the only microwave signal generator offering wideband vector modulation in a single, integrated instrument. The Agilent PSG vector signal generators feature an internal, dual-mode baseband generator that combines the capabilities of a wideband (80 MHz) arbitrary waveform generator with the sophisticated coding power of a real-time baseband generator. This capability sets new points of reference for straightforward, repeatable microwave communications signal generation and enables engineers to solve many of the problems they experience today when testing with golden devices and custom test systems.

In addition, the baseband generator's deep playback memory and waveform sequencing capability facilitates the generation of complex radar test patterns. Arbitrary waveforms representing pulsed radar signals can be defined in the time domain using industry standard tools — including MATLAB®, Agilent's Advanced Design System (ADS) or Signal Studio software — and played back using the internal baseband generator. This technique enables custom pulse shaping, accommodates pulse compression, and eliminates many of the synchronization issues associated with pulsing modulated signals using traditional analog techniques.

Since many microwave communications systems lack standardization, Agilent developed the PSG to easily adapt to custom test needs. The Agilent PSG Vector Signal Generator provides a suite of custom I/Q modulation formats, such as Phase Shift Keying (PSK), Minimum Shift Keying (MSK), Frequency Shift Keying (FSK) and Quadrature Amplitude Modulation (QAM). By simply selecting one of these formats and setting high-level parameters such as data type, filtering and symbol rate, engineers can quickly generate a test signal for most microwave communications formats.

"As microwave systems increase in complexity, engineers working on radar, broadband wireless, and satellite communications systems have been struggling to find a way to make measurements that truly simulate the real-world environment in which their systems will eventually operate," said John Vink, general manager of Agilent's Signal Sources Product Generation Group. "With this in mind, Agilent developed this new performance vector signal generator that not only breaks through the 6 GHz frequency barrier, but also continues Agilent's commitment to provide the lowest phase-noise performance, highest output power and superior specified level accuracy for microwave frequencies."

The Agilent E8267C Vector Signal Generator provides wideband vector modulation at frequencies up to 20 GHz and features an available high-performance internal baseband generator with 80 MHz of RF modulation BW and 32 MSamples of baseband memory. The PSG Vector Signal Generator also features the following:

The Agilent 8247C CW and E8257C Analog Signal Generators provide signal generation at frequency ranges to 20 or 40 GHz. New features include the following:

This new generation of PSG signal generators marks the first appearance of Agilent Signal Studio software for microwave applications. Introduced in May 2001, Signal Studio is a suite of Microsoft Windows®-based software tools used to create waveforms for popular communication formats. Pulse Builder Signal Studio Software is a radar emitter test pattern generator that uses the Agilent E8267C PSG Vector Signal Generator to create pulsed signals. The software's user-friendly interface simplifies test pattern generation by enabling the set up of custom pulse sequences while keeping the complicated mathematics required for calculating the I/Q waveform samples transparent to the user.

Available as Option 420 for the E8267C PSG Vector Signal Generator, Pulse Builder is the first of many software applications that will be available for the E8267C to enhance the platform's capability.

Also new to Agilent's lineup of time saving software tools is the Agilent PSG/ESG Download Assistant. This tool allows the user to create unique waveform files within MATLAB and then download them directly from the MATLAB environment into a PSG or ESG vector signal generator.
