Introduction

E4438C ESG

vector signal generator

Definitions

Agilent Technologies E4438C ESG vector signal generator incorporates a broad array of capabilities for testing both analog and digital communications systems. Flexible options provide test solutions that will evaluate the performance 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 E4438C ESG vector signal generator an excellent choice for wireless communications system testing now and in the future.

Choose your required frequency range as an Option when configuring your

E4438C ESG vector signal generator. Please refer to the E4438C Configuration Guide for complete ordering information. Literature number 5988-4085EN.

Specifications (spec): Specifications describe the instrument’s warranted performance and apply after a 45 minute warm-up. All specifications are valid over the signal generators entire operating/environmental range unless otherwise noted. Supplemental character- istics, denoted typical or nominal, provide additional [nonwarranted] information useful in applying the instrument. Column headings labeled “standard” imply that this level of performance is standard, without regard for option configuration. If a particular option configuration modifies the standard performance, that performance is given in a separate column.

Typical (typ): performance is not warranted. It applies at 25°C. 80% of all products meet typical performance.

Nominal (nom): values are not warranted. They represent the value of a parameter that is most likely to occur; the expected or mean value. They are included to facilitate the application of the product.

Standard (std): No options are included when referring to the signal generator unless noted otherwise.
