The Vector Network Analyzer, VNA, is a form of RF network analyzer widely used for RF design applications. The LA LA19-13-04B Vector Network Analyzer is a USB controlled, computer-driven VNA suitable for measuring a wide range of devices from 0.3MHz to 8.5GHz. LA19-13-04B uses a four receiver architecture allowing support for 8 error terms calibration techniques as well as traditional 12 error terms correction. In addition to internal bias-Ts for biasing active devices, the internal couplers can be bypassed to test, for example, high power devices. The instrument is housed in a small, lightweight package making it very portable. The control software provides a wide range of features including memory functions, data compare (compares measured data with reference data loaded from disk), network de-embedding, limit lines, time domain and reference plane extension. Measuring parameters include S11, S22, S21, S12, mixer conversion loss, return loss, isolation and compression, P1dB gain compression measurement, AM to PM conversion measurement and a signal generator function able to operate in CW or frequency sweep modes. Demo Kit – SOLT is also an essential tool for vector network analyzing and is a must. See Demo Kit – SOLT from photo section.
