The Current Monitoring probes may be used whenever RF current measurements are required. Current measurements are made by placing a current carrying conductor within the “sensing” window of the probe and measuring the probe’s output voltage with an RF detector. Calibration of the probe permits the conversion of the voltages measured to current. Current measurements can be made over the frequency range shown in the transfer impedance curve furnished with each probe. There is virtually no loading of the circuit and the technique permits normal operation of the device under test during measurements. |

The common mode current disturbance signal can be delivered to the EUT using a variety of coupling networks to inject the signal onto the unscreened cables, shielded cables, balanced cables, coaxial cables and power mains. Decoupling networks are used to insure that the disturbance signal does not influence the auxiliary equipment and are placed between the EUT and the auxiliary equipment. |
