R140 1-Port 14 GHz Analyzer

R140 Vector Network Analyzer (cable and antenna analyzer) delivers lab grade performance in a handheld device. This patented (US Patent 9,291,657) analyzer can be connected directly to the antenna or other DUT without the need for a test cable, eliminating measurement uncertainties inherent to cables. Resulting in highly dependable performance and calibration stability. The 1-port VNA comes with all the features engineers have come to expect included standard in our software.


R140 VNA includes an RF measurement module and R software application which runs on Windows or Linux operating system on a PC, laptop, tablet, or x86 board computer connecting to the measurement hardware via USB interface. R software can be installed on multiple computers that share the use of the analyzer measurement module. The R140 network analyzer can be used in the field, in the laboratory, and in production testing. The VNA can be integrated into production test system via Manufacturing Test plug-in.


VNAs and ACMs 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.
