Overview

The Schwarzbeck CF 9651 is a calibration fixture designed for use with bulk current injection (BCI) clamps and current monitoring probes. It provides a defined and repeatable setup for calibrating transfer impedance and verifying the performance of current clamps used in conducted immunity testing.

At The EMC Shop, customers typically use the CF 9651 together with BCI clamps such as the SW 9600 series to establish accurate calibration conditions before testing. By positioning the clamp around the fixture, engineers can generate a known current path and validate measurement accuracy across the required frequency range.

This ensures consistent test results, improves measurement confidence, and supports compliance with EMC standards such as ISO 11452-4 and related specifications.
