S5243 2-Port 44 GHz Analyzer

The S5243 is a 2-port 44 GHz Vector Network Analyzer is CMT’s highest frequency Compact VNA. It features excellent dynamic range and fast measurement speed in a compact package with the maximum standard software feature set.


S5243 VNA includes an RF measurement module and S2 Windows or Linux operating system on a PC, laptop, tablet, or x86 board computer connecting to the measurement hardware via USB interface. S2 software can be installed on multiple computers, making it easy to share the use of the analyzer measurement module.


VNAs are delivered with factory calibration certificates containing no data. The add-on option for ISO17025/Z540-1 Accredited, Traceable Calibration Certificate and Uncertainties is available and needs to be specified at time of order.
