has introduced a 4-port configuration for its ME7838A VectorStar VNA that extends the unit’s measurement capability to 750GHz and higher.
With this new configuration, engineers designing 4-port or differential millimetre-wave (mm-wave) components can sweep power across a wide range at frequencies up to 750GHz using external mm-wave modules without the need for manual attenuators.
VectorStar ME7838A vector network analysers have excellent stability with the extremely 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 method delivers stable mm-wave power even at low levels and reduces the risk of overdriving power sensitive mm-wave devices.
