06 | Keysight | Measurement Applications for the E6640A EXM Wireless Test Set - Solution Brochure Broadest Multi-Format Coverage EXM delivers fast and accurate measurements using high-throughput manufacturing applications for cellular and wireless connectivity devices. These feature-rich applica - tions allow you to choose the capabilities you need and help ensure you achieve your manufacturing test goals for today’s multi-format devices. X-Series measurement applications Based on the library of industry-proven X-Series measurement applications for benchtop signal analyzers the X-Series cellular and wireless connectivity applications are tailored for the EXM. True to the traditions of X-Series products, each application allows you to characterize, troubleshoot, and rapidly create test code for the manufacture of your design. For cellular communications measurement, these applications cover a full range of technologies — from existing 2G/3G systems to evolving 3.5G and 4G communication systems. These measurement applications are based on the 3GPP and 3GPP2 standards, and closely follow standards as they change, allowing you to stay on the leading edge of your design and manufacturing challenges. The wireless connectivity measurement applications cover a full range of technologies, including 802.11a/b/g/n/j/p/ac, WLAN MIMO, Bluetooth 1.0 to 4.2, ZigBee, WiSUN (MR-FSK), and Mobile WiMAX. Giving you added flexibility, you can choose from two product categories of EXM X-Series applications for cellular and wireless communication technologies: V90xxB These applications cover transmit measurements only. They allow you to use the 150 waveform slots included with each EXM for output of specific test waveforms. If addi - tional waveforms are needed, additional slots can be purchased in 5-pack or 50-pack quantities. Y90xxB These applications provide the transmit measurements as well as the ability to play unlimited waveforms for the technology purchased, eliminating any maximum waveform restriction for those test cases that require a large number of waveforms 1. Signal Studio applications Keysight Signal Studio helps you simplify signal creation for receiver measurement and it is the benchmark for test stimuli in the cellular industry. Signal Studio is a comprehen - sive suite of 2G, 3G, and 4G-compliant solutions. These applications address current and emerging standards with tools that reduce the time you spend on signal creation and simulation while providing a high degree of flexibility in waveform creation. EXM measurement applications available by cellular and wireless technology are summarized in Tables 1 thru 4. 1. Receiver test waveforms may be played through EXM’s source ARB function to make the receiver measurements that are available in the chipset being tested. Waveforms may be provided by the chipset provider, generated by the user through Keysight Signal Studio software, or using any of several third-party software programs.
