MW-SCA50 Coaxial HF-Low-current probe

Part Number

MW-SCA50

Designation

Coaxial HF-Low-current probe

APPLICATIONS

Low-Leakage-Current Testing

HF & Microwave Probing

Description

The coaxial Probe is designed for low-level signal probing (lower than 10fA@150°C)

- The probe's single unit design is especially desirable for the best possible electrical characteristics
- The Coaxial Probe is also offered with optional Ground Plane, Kelvin and resistor series /parallel configurations
- The Probes are constructed of microwave-quality components with a 50 Ohm semi-rigid cable shield being achieved through the utilisation a Teflon dielectric
- The probe contact protrudes from the shielding by .150" (3 mm) to maintain low-level signal noise to the probe
- Tips available (replaceable) from 0.5 µm to 20 µm
- The connector is a standard SSMC
