Anritsu extended VectorStar sys frequency coverage to 750GHz with 4-port config

Anritsu Company has introduced a 4-port configuration for its ME7838A VectorStar that extends the Vector Network Analyzer (VNA) measurement system’s capability to 750 GHz and higher. The ME7838A provides R&D engineers designing 4-port or differential millimeter-wave (mm-wave) components with the ability to sweep power across a wide range at frequencies up to 750 GHz using external mm-wave modules without the need for manual attenuators.

The supplier claims that the VectorStar ME7838A is the first mm-wave VNA system with real-time power leveling and has best-in-class stability with the widest power level control. The mm-wave system 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 mmwave power at low levels and reduces the risk of overdriving power-sensitive mm-wave devices. The ME7838A VectorStar also achieves faster power calibrations.

The 2 port system configuration includes the MS4640A VectorStar and 3739A/SM6522 test set, which operates mm-wave modules.

It can test 4-port components and differential devices such as amplifiers used in e-band communications systems, automotive collision avoidance systems, airport radar, materials measurement, and homeland security imaging systems.
