mm-wave VNA system offers real-time power leveling and high stability with wide power level control. It detects IF and RF power and provides correction to the mm-wave power in real time and without the need for software correction feedback. The method delivers stable mm-wave power even at low levels and reduces the risk of overdriving power-sensitive mm-wave devices – inherent in other systems. Faster power calibrations are also achieved with the ME7838A VectorStar, compared to competitive mm-wave VNAs, helping to reduce test time and cost of test.
A 2-port system configuration includes the MS4640A VectorStar and 3739A/SM6522 test set, which operates mm-wave modules.
The VNA system can accurately test 4-port components, as well as differential devices, such as amplifiers used in e-band communications, automotive collision avoidance, airport radar, materials measurement, and imaging systems.
