In this application, the LCR meter supports the test phase of iterative development processes to optimize device performance. The critical difference is that this higher frequency performance allows you to test components in situ on a circuit board at their intended operating frequencies to validate their performance in real-world conditions. LCR meters go beyond the capabilities of typical digital multimeters by providing more accurate and precise measurements across broader frequency ranges. These measurements are vital in characterizing components' real-world impedance, precision, and performance when integrated into your circuit design. However, their application goes beyond simple measurements to supporting precision evaluation and validation of components to optimize your design.Ī good LCR meter can measure inductance, capacitance, and resistance along with more complex parameters, including phase angle, dissipation factor, reactance, and conductance. The meter will then calculate the impedance values from these three measurements. They achieve this function by measuring current flow through the component or circuit you're testing, the voltage across it, and the phase angle between the two measurements. The software will cross probe to the item on the target document.At the basic level, these are potent instruments for measuring a circuit's inductance, capacitance, and resistance with precision and speed. Position the crosshair on any component or net then click.
You can use this tool by choosing Tools > Cross Probe from the main menus. the PCB document and the schematic document are open on different monitors. The best way to use this tool is by working on two monitors, i.e. Altium Designer has a Cross Probe tool that helps you to find components on the PCB by clicking on the component in the schematic and vice versa. Some components must be placed close to each other in order for them to work correctly. Additionally, good placement of passive components will allow forming a proper decoupling and device configuration.Ĭorrect component placement requires attention to the schematic. Good placement of high-speed ICs allows your interfaces to run at maximum speed without any errors. The correct placement of the power components will create good conditions for the correct function of the power-distribution network, help to avoid unnecessary voltage drop-downs, and reduce power ICs noise on high-speed ICs. The correct placement of the connectors can be organized to ensure the correct ergonomics of the device. It is at this stage that a significant part of possible future problems can be solved. Competent placement of components has a huge impact on the quality of board routing and behavior. Now we've come to one of the most interesting parts of the PCB design process - component placement.
