The SW9606 current clamp is used to inject radio frequency current into a wire or wire harness. The maximum wire diameter is 23mm. This product complies with CISPR16-1-2 or DIN EN 55016-1-2. The conversion ratio is 1:0.125 (I=0.125U), that is, the converter impedance is 8 ohms, and the insertion loss is 16 dB under a 50 ohm system. If the BNC connector has an 8uV voltage injection, there will be 1uA current injection in the wire bundle, that is, 18dBuV voltage injection in the BNC connector, and 1dBuA current injection in the conductor.
This clamp can also be used at frequencies lower than 900kHz, in this case, use it against the conversion factor diagram.
Low insertion loss, sufficient sensitivity, almost unlimited measurement.
The SW9606 current probe is used to measure the RF current on a single wire or wire bundle. The test principle is called BCI. The BCI principle is a power-saving mode of anti-interference test, which is applied to cable bundles or single conductors without interrupting the normal operation of the object under test.
This current clamp can be connected to the cable at a very fast speed. During the BCI test, the required disturbance level is provided by frequency. The running status of the measured object must be monitored at the same time.
This current clamp can also be used to measure the RF common mode current (asymmetric current) on a single wire or wire bundle. Due to the effect of current saturation at low frequencies may occur, it will rapidly change the low frequency to a certain high frequency.
Only the algebraic sum of the currents being considered is important, so individual conductors are more important than complete wire bundles. To evaluate the effect of current saturation at low frequencies, an insertion loss of 1dB needs to be added to the frequency .
