Introduction

Standard Agilent Technologies ESG family RF signal

generators incorporate a broad array of capabilities for

testing both analog and digital communications systems.

Adding flexible options provides a test solution that will

evaluate the performance of a communication system to

the requirements of nearly all current and proposed air

interface standards. Many test functions can be customized

to meet the needs of proprietary and other nonstandard

wireless protocols as well. You can configure your

instrument to address a wide variety of tests—from

altering nearly every aspect of a digital signal or signal

operating environment to creating experimental signals.

This flexibility, along with an architecture that accepts

future enhancements makes the ESG family an excellent

choice for wireless communications system testing now and

in the future.
