Type 9335-2 Multiple Impedance Coupling Clamp
impedance matching injection probe
The Solar Type 9335-2 Multiple Impedance Coupling Clamp is a split toroid, designed as a versatile impedance matching transformer used in conjuction with a generator as an injection probe for conducted susceptibility tests such as methods CS10 and CS11 of MIL-STD-462, Notice 5; CS116 of MIL-STD-462D; DO-160G, Section 22, other specifications.
INJECTION – High power transient generators with source impedances from 0.25 Ω to 50 Ω can use this probe to deliver high peak voltage or high current pulses into the wires or cables passing through the window of the device.
The Type 9335-2 Multiple Impedance Coupling Clamp provides:
1:1.0 voltage or current transfer
These ratios are selected by connecting to one of the four BNC connectors on the side of the Type 9335-2.
Figure 1 shows a family of curves representing the transfer functions for each connector port when the device is used as an injection probe. Through connector port selection, the open circuit voltage or short circuit current can be adjusted for maximum transfer of energy. This is especially useful as an accessory to the Solar Model 9354-2 Transient Pulse Generator with its differing source impedences, enabling it to meet various open circuit voltage and short circuit current requirements.
The design of the Solar Type 2925-1 Calibration Fixture was carefully tailored to provide a 50 Ω characteristic impedance based on the specific dimensions of the Type 9335-2. The fixture maintains a low standing wave ratio from 10 kHz to 10 MHz in a 50 Ω circuit.
