On-Wafer

The answer to your high-stability broadband on-wafer device characterization needs.

VectorStar™ ME7838A Broadband VNA System — Don't let expired calibrations spoil your data.

The VectorStar ME7838A VNA delivers 109 dB dynamic range at 110 GHz for high-sensitivity measurements across 70 kHz to 110 GHz (up to 1 THz with VDI or OML modules) with 0.1 dB and 0.5 degrees S₂₁ stability over 24 hours. This stable broadband performance means you can make high accuracy measurements all day, with the confidence that your calibration remains rock solid! Spend less time calibrating and more time measuring.

For on-wafer measurements, VectorStar offers the smallest, lightest and easiest to position frequency extension modules which connect directly to wafer probes. Bulky, difficult-to-mount frequency extension modules are a thing of the past, even when working with 4-port measurements. New DifferentialView™ enhances accuracy with true mode stimulus (TMS) measurements—giving you confidence to achieve higher product specifications through testing.
