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 characteristics, 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.

Repeatability measures the ability of the instrument to return to a given power setting after a random excursion to any other frequency and power setting. It is a relative measurement that reflects the difference in dB between the maximum and minimum power readings for a given setting over a specific time interval. It should not be confused with absolute power accuracy, which is measured in dBm.

Specifications for Frequency and Power Characteristics

1. Parentheses denote typical performance.

2. Refer to frequency bands on page 12 for N values.

3. Harmonic performance outside the operating range of the instrument is typical.

4. Spurs outside the operating range of the instrument are not specified.

5. Specifications apply for FM deviations < 100 kHz and are not valid on FM. For non-constant amplitude formats, unspecified spur levels occur up to the second harmonic of the baseband rate.

6. Specifications apply for CW mode only.

7. Calculated from phase noise performance in CW mode only at -2.5 dBm for standard instruments, -0.5 dBm with Option 506, and +2.5 dBm with Option UNB.

8. For other frequencies, data rates, or bandwidths, please contact your sales representative.

FM path 1 and FM path 2 are summed internally for composite modulation. The FM 2 path is limited to a maximum rate of 1 MHz. The FM 2 path must be set to a deviation less than FM 1 path.

Specifications for Analog Modulation

1. All analog performance above 4 GHz is typical.

2. For non-Option UNJ units, specifications apply in phase noise mode 2 [default].

3. Refer to frequency bands on this page to compute specifications.

4. Parentheses denote typical performance.

5. At the calibrated deviation and carrier frequency, within 5 °C of ambient temperature at time of calibration.
