Signatone Probe Stations and Accessories
Signatone has manufactured analytical probe stations in the USA since 1968. Configure a manual, semi-automatic, RF / mm-wave, four-point resistivity, high-power, or thermal probe station for on-wafer device characterization from DC to 1.1 THz, on wafers from 5 mm to 300 mm. Every system is factory-direct, built to order, and backed by the engineers who designed it — with the datasheet on every card below.
Manual & Analytical Probe Stations
Signatone's CheckMate and S-1160 probe stations handle DC parametric, CV/IV, high-power, and RF on-wafer test on 150 mm to 300 mm wafers. Choose a precision manual bench or step up to motorized and semi-automatic control, with three-point chuck planarization, micrometer theta rotation, and up to ten micropositioners on the platen.
RF · mm-Wave · THz Probe Stations
WaveLink probe stations are purpose-built for on-wafer RF, mm-wave, and THz measurement — RF to 110 GHz with 2- and 4-port setups, and extender-based configurations from 110 GHz to 1.5 THz. Platens carry multiple RF and DC positioners at once, with local-enclosure variants for shielded, light-tight measurement.
Resistivity Systems
Signatone has built four-point probing solutions since 1968. The Pro4 covers manual sheet and bulk resistivity from 10 µΩ to 100 MΩ per square; the QuadPro2 automates it with full-wafer 2D / 3D contour mapping, up to 14,000 test points, and dual-configuration testing per ASTM F84-99 with NIST-traceable calibration.
Compact & Shielded Systems
The H-150 is an economical bench-top probe station for DC and CV/IV testing on 5 mm to 100 mm samples. Pair any station with the PSDB dark box for light-sensitive, high-power, and high-temperature work, plus multipurpose probe-card adapters and specialty chucks.
Positioners, Probes & Optics
The contact hardware behind every probe station — micropositioners from general-purpose 3-axis to large-area RF / mmW extender mounts, the SP-BT microwave probe series, high-voltage and low-noise probe holders, probing-grade microscopes, and in-house thermal chucks with 0.1 °C control.
