The ME7838A is the first broadband VNA to provide good raw directivity throughout the entire frequency range, due to its innovative design and elimination of the MUX combiners used in traditional systems. This advantage, as well as the fact that the ME7838A transitions at 54 GHz, gives the broadband VNA the widest dynamic range in its class – 107 dB at 110 GHz and 92 dB at 125 GHz. With the ME7838A design, mmWave modules can be mounted close to or directly on the wafer probe. The result is that the ME7838A performs the most accurate gain compression measurements on high-frequency active devices in the industry. The VectorStar® broadband system provides an accurate and fast real-time method to sweep power for compression measurements. The approach employed in the ME7838A takes less time, is less tedious, and more accurate than the conventional method of adjusting power level in the millimeter band through the use of electronically controlled mechanical attenuators and power linearity correction tables. The ME7838A, equipped with the 3743A mmWave module, can accurately measure 28 Gbps SerDes transceivers at the higher frequencies required for proper analysis.Īmong the many advantages of the ME7838A is improved RF performance, due to an industry first, real-time power leveling control that provides the best power accuracy and stability to power levels as low as -55 dBm. The ME7838A is also well suited for conducting signal integrity measurements on emerging high-speed designs, such as 28 Gbps serializer/deserializer (SerDes) transceivers used on servers, routers and other networking, computing and storage products.
