Trace Impedance Measurement
« on: August 17, 2016, 09:21:08 pm »
Hello guys!
Is there any way to measure the impedance of a cooper trace in Altium Designer?
Best regards!

Controlled impedance routing is enabled when there are plane layers in the stackup.

Altium's impedance control is very basic, limited to setting the trace width during routing, based on the calculated value.  There is no check for adjacent copper: a very large polygon pour will not be considered a reference plane (because a polygon is routing copper), and conversely, you are not prevented from routing controlled-impedance traces over a plane keep-out region.

If you need accurate trace impedance, signal quality, or SWR calculations, consider getting an RF-oriented board simulator.

You can trace the impedance measurement by controlling impedance or by applying impedance formula editor. You need to achieve impedance matching by matching components and routing the board to give the required impedance.

Thank you all for your answers!
I am very new with altium and I don't know how to do a lot of things!
