The Advantest R3753AH is a 3-port vector network analyzer delivering S-parameter measurements from 5 Hz to 500 MHz with dynamic range up to 115 dB. It characterizes multiport devices through simultaneous measurement of all nine S-parameters (S11, S22, S33, S21, S12, S31, S13, S23, S32) and provides impedance (Z) and admittance (Y) parameter conversion. The instrument displays data in rectangular, Smith chart, and polar coordinate formats across linear/logarithmic amplitude, phase, group delay, VSWR, and complex number representations.
