Anritsu has released the world’s first single sweep VNA-Spectrum analyser solution Supporting 70 kHz to 220 GHz. The VectorStar is capable of spectrum-based measurements and conducting single connection VNA to verify active and passive devices during the design, troubleshooting, or characterization stages. The test instruments also allows for spectral domain measurements of harmonics, spurious, other distortion products, and general frequency content. The spectrum analyzer option is compatible with all baseband VectorStar models – broadband and banded system configurations. VNA analyser Power calibration can be conducted at the probe tip for greater accuracy and repeatability. Furthermore, any port of the device can be used as a receiver for scaler measurements when the VNA source of the instrument is used as a stimulus.
According to the company, the VectorStar allows engineers to analyze VNA-like and spectrum-analyzer-like response of a device under test (DUT). Moreover, the spectrum analyzer option is compatible with all baseband VectorStar models – broadband and banded system configurations. The device also allows for quick transfer of a challenging VNA measurement to the spectrum analyser without changing the test setup or using multiple instruments. This feature is extremely useful for applications involving mixers and amplifiers, including those with multiple outputs or input-output comparisons.
The company claims that the VNA-spectrum analyzer solution is ideal for on-wafer measurements. It leverages VectorStar’s inherent advantages of making a direct connection to an on-wafer device. Mounting and demounting of on-wafer devices, which can cause major errors in measurement, are eliminated with the solution. Spectrum analysis for broadband and banded is also available with Anritsu or other millimeter (mmWave) modules. The VectorStar comes in two configurations, the standard VNA mode supports point-based spectrum analysis for faster measurements, and another model is a traditional sweep-based spectrum analyzer.
