EPS200MMW – Easy Sub-THz Measurement Setup

See how easy it is to set up the EPS200MMW manual probe system for 325 GHz on-wafer measurements using the sub-THz SIGMA integration kit.


EPS200MMW – Setup for Various mmW Bands on Single Manual Probe System

Sharing measurements at several mmW bands on a single probe station may present a challenge. We make set up easy for a variety of measurements with SIGMA integration kits.


1.1 THz Calibration on an EPS200MMW Manual Wafer Probe Station

This video gives an overview of a typical calibration run at 1.1 THz on a Cascade EPS200MMW manual probe station with THz SIGMA Kit. WinCal XE calibration software runs directly on a 67GHz PNA from Keysight Technologies. The frequency extenders are 1.1 THz models from Virginia Diodes and probes are Cascade T-Wave Probes.
