Anritsu reveals VectorStar ME7838A4 broadband network analyzer

Test solutions company Anritsu Company revealed the launch of VectorStar ME7838A4 4-port broadband vector network analyzer (VNA) system.

VectorStar ME7838A4 analyzer features differential broadband sweep from 70 kHz to 110/125 GHz and utilizes the smallest mmWave modules to conduct stable and fast measurements when characterizing differential devices.

The new ME7838A4 provides on-wafer and signal integrity engineers with a new level of performance when conducting differential measurements so they have greater confidence in their next-generation communications system designs, said Anritsu Company.

3743A mmWave modules are much more compact than competitive alternatives, for easy mounting on space-limited wafer probe station platens. Smaller and lighter modules improve overall performance, including superior raw directivity performance that results in superior calibration stability. Modules are available that can extend the VectorStar ME7838A4 to a 4-port 145 GHz system.

The VectorStar ME7838A4 4-port broadband system uses an internal substrate-mounted source for thermal stability, resulting calibration and measurement stability of 0.1 dB over 24 hours. It features measurement speed of 55 ms for 201 points at 10 kHz IFBW.

Because internal frequency multiplication begins at 54 GHz in the VectorStar ME7838A4 compared to 67 GHz for other 4-port broadband systems, RF cable losses are reduced for improved dynamic range and phase stability.

The company said that probe station position costs are lower due to the compact size and lighter weight of the modules. There is significant savings from the longer interval times between calibrations, said Anritsu Company.
