ADVANTEST R3765CG Network Analyzer

INTRODUCTION

Vector Network Analyzers in the R3765CG/3767CG propose a new RF circuit analysis procedure. Range of measurement frequency is 300 kHz to 3.8 GHz (R3765CG) or 300 kHz to 8 GHz (R3767CG). A unique high-speed signal processing technology adopted to the R3765CG/3767CG has realized enhanced measuring speed. The R3765CG/3767CG are a model with a built-in S parameter test set to deal with forward/reverse directions measurements. Further, lined up, as optional, are a model with a built-in 3- port test set and a model with a built-in 4-port test set. Additional installation of input channels to the receptor assembly of these multi-port models will make them capable of performing simultaneous measurement of 2 different paths to be tested. Adopting this method will result in substantial improvement to measuring efficiency of multi-port devices. Adopted is 8.4-inch TFT color LC monitor that is capable of displaying 4-sectioned screens at a time, thus making possible of choosing independently one measuring path in each section, realizing simultaneous display of a maximum of 4 paths and 8 parameters that results in an instantaneous analysis of variety of items subject to measurements. Sweep time is as short as 150 µs/point, thus realizing a further high speed.

4-port Full Calibration 

By 4-port device testing, it is not possible to remove thoroughly error factors from a system tested by a 2-port full calibration. For high accuracy testing of 4-port devices, error factors other than those in the paths being tested must be taken into consideration. Models having built-in 4-port test set are also equipped with 4- port full calibration function that solves such a problem. When measuring a 4-port device, full 4-port calibration thoroughly corrects errors from measurement system of 4-port networks. Accordingly, when measurements on the path between port 1 and 2 are performed, measurements on the paths between all ports are performed. In other words, the measurement on all possible six paths between 4 ports (1-2, 1-3, 1-4, 2-3, 2-4, and 3-4) are performed, thus all of sixteen S parameters have been obtained.
