For simple single-port or dual-port devices, 2-port mode can be used for measurement; for more complex multi-port networks, such as mobile phone front-end modules, the 4-port mode can simultaneously measure all signal paths, obtaining comprehensive network parameters at once, greatly improving testing efficiency.
- Balanced Measurement Capability The instrument has a built-in balanced measurement function, which can be used to test balanced components such as SAW filters, differential amplifiers, and high-speed digital cables/connectors. During balanced measurement, it can effectively separate common-mode and differential-mode signals and accurately measure mixed-mode S-parameters, providing detailed and accurate data support for the design and optimization of balanced circuits.
(2) Fixture and Impedance-related Functions
- Fixture Embed/De-embed It has fixture embed/de-embed function. In actual tests, the test fixture will introduce some errors into the measurement results. Through this function, the instrument can compensate for the influence of the fixture, eliminating the loss and reflection introduced by the fixture, restoring the true performance of the device under test, and ensuring the accuracy of the measurement results.
- Port Characteristic Impedance Conversion It supports port characteristic impedance conversion and can flexibly adjust the impedance matching of the instrument port according to the characteristic impedance requirements of the device under test. For example, for some devices that require 50Ω or 75Ω impedance matching, the E5070B can easily achieve the corresponding impedance setting, ensuring the integrity of the signal during transmission and avoiding signal reflection and measurement errors caused by impedance mismatch.
(3) Frequency Offset Mode
(4) Built-in Programming Language and Automation
- Built-in Visual Basic® for Applications (VBA) It has a built-in VBA programming environment. Users can use the powerful programming functions of VBA to develop automated test programs according to their specific test needs. By writing code, the automated control of the instrument can be realized, such as automatically setting measurement parameters, starting measurement, data acquisition and analysis, etc., greatly improving testing efficiency and the accuracy of data processing, especially suitable for scenarios that require a large number of repetitive tests.
- Measurement Wizard Assistant (MWA) Software It is equipped with Measurement Wizard Assistant software, which provides users with an intuitive and convenient operating interface. Even engineers who are not very familiar with the operation of network analyzers can quickly complete complex measurement settings through the guidance in the software and easily start various RF measurement work, reducing the threshold of instrument use and improving work efficiency.
