The Compact Series of Vector Network Analyzers (X1244 and X1444) are designed for testing, tuning, and developing devices in both manufacturing and laboratory settings as part of automated measurement setups. The X1244 and X1444 are 2- and 4-port Vector Network Analyzers operating in the 10 MHz to 44 GHz frequency range. These are the highest-frequency vector network analyzers of the Compact series. They deliver an excellent dynamic range and high measurement speed in a compact enclosure, offering a comprehensive range of software functions to tackle most real-world production measurement challenges.
The X1244 and X1444 Vector Network Analyzers support pulse mode measurements (PLS-X software option).
The device includes an embedded pulse modulator capable of generating pulse signals with a minimum duration of 20 ns, along with a synchronizer and logic generators that support various pulse measurement modes: «Point-in-Pulse», «Pulse profile» and «Asynchronous pulse» mode. The minimum time resolution in Pulse Profile mode is 100 ns.
For convenient, high-quality calibration of the network analyzer, it is recommended to use automatic calibration modules, including XC5244 for measuring RF paths with 2.92 mm and 2.4 mm connectors.
Software
The analyzers are controlled by the 2X-VNA program from an external PC running dedicated software, which processes information and provides GUI. A USB 2.0 interface is used to communicate with the PC.
