Type 4138 is designed for high-level and very high-frequency measurements and measurements in confined spaces. Being externally polarized, Type 4138 must be used with a classical preamplifier.

High-level and very high-frequency measurements
Applications which require a high degree of spatial resolution or where space is limited, for example, model testing
