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 ApplicationsHigh 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.
