Specifications Brochure
Specifications require the injection of large high frequency currents into cable bundles and individual wires, using inserted secondary toroidal transformers placed around the conductors being tested.

The 9120-1N Injection Probe comes in a split toroidal design where the probe can be opened up and clamped over the wire(s) under test. The probe is calibrated for insertion loss and transfer impedance in a test fixture designed for the particular window size.This fixture provides a signal path with a low Voltage Standing Wave Ratio.

Solar Electronics 9120-1N Applications
High power R.F. amplifiers with 50 ohm output impedance are used to deliver voltage to the injection probe. The wire or cable through the window of the probe acts as a secondary of the toroidal transformers. This test method is intended to be used instead of earlier methods, such as CS-01, CS-02, and RS-02 of MIL-STD-461.
