Anritsu ME7838A VectorStar VNA system

A four-port configuration for the ME7838A VectorStar VNA extends the unit’s measurement capability to 750 GHz and higher. The instrument now provides engineers, designing four-port or differential millimeter-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 device, said to be the first mm-wave VNA system with real-time power levelling, has good stability with the wide power level control. The mm-wave system detects IF and RF power and provides correction to the mm-wave power in real time, without the need for software correction feedback.

This delivers stable mm-wave power, even at low levels, and reduces the risk of overdriving power sensitive mm-wave devices.
