 Network Analyzers using PXI software

The Module contains several different transmission and reflection impedance states, as well as electronic changeover switches, two or four RF connectors, and a USB connector. RF connectors are intended for connecting to VNA test ports, and a USB connector is intended for controlling.

Module

States

ACM2506, ACM2509, ACM2708, ACM4000T, ACM6000T

6 reflection states (three for each port), a THRU, and an attenuator.

ACM2520

8 reflection states (four for each port), a THRU, and an attenuator.

ACM2543, ACM8000T

10 reflection states (five for each port), a THRU, and an attenuator.

ACM4509, ACM8400T

16 reflection states (four for each port), a THRU, and an attenuator.

ACM4520

12 reflection states (three for each port), a THRU, and an attenuator.

Calibration is performed by automatically connecting internal transmission and reflection impedance states to the VNA test ports.

Calibration allows determining systematic errors according to the VNA model. The data obtained after calibration is used to correct S-parameter measurement results to increase measurement accuracy.
