Giới Thiệu Máy Phân Tích Mạng Vector 8GHz, LA 19-13-03


– 300 kHz to 8GHz Operation

– 120 dB dynamic range

– 200µs per point sweep speed

– Access to internal receivers

– Fully featured signal generator mode

– Small footprint


The LA19-13-03 is our latest PC-driven Vector Network Analyser. It provides great flexibility, fast speed and wide dynamic range. It is useful for measuring a wide range of devices from 300 kHz to 8 GHz with 10 Hz resolution. By means of external links on the front panel, the internal couplers can be bypassed for direct access to the internal receivers. This flexibility allows, for example, high power amplifier measurements to be carried out using an external booster amplifier and couplers. It is housed in a small lightweight package making it very portable.
The user interface control software provides many useful features including memory functions, limit lines, de-embedding, time-domain and reference plane extension. Also, utilities such as measurement of power at the 1 dB gain compression point as a function of frequency are provided. Support for third party tools such as VEE and LabView is by means of  DLL libraries.The optional 3.5mm calibration kits use Rosenberger calibration standards and are supplied with measured load data resulting in excellent kit performance.
