EMI Receiver Instructions for Use
Clamp the current injection probe to the signal cable or power line under test, and pass the output signal of the signal source through the
The power amplifier is amplified and added to the current injection probe, and the current detection probe is used to monitor the injection into the wire
Signal current size. In this way, the purpose of sensitivity measurement can be achieved. As shown in Figure 4.6.

4.3. Measuring common-mode and differential-mode signals with a common-differential mode separator
The traditional conduction measurement can only measure the total amount of conduction interference of the device under test from the L/N detection terminal of the LISN.
The total amount of interference includes common-mode components and differential-mode components. I don't know how much each of the common-differential mode components is. This gives EMI
It is difficult for design and modification engineers to choose which filter to use.
With the common and differential mode separation function in the EA3040B integrated analyzer, the common mode can be separated from the total interference
Component and differential mode component, which is convenient for designers and rectification personnel to carry out interference analysis and directional processing.
The specific operation of the common-differential mode separation function is explained below with specific examples.
1) Device connection
Connect the equipment according to the GJB151A/152A conducted emission measurement in section 6.3. After the actual connection as shown in the figure
