Technetters, how does one make impedance measurements on what I think is a grounded coplanar waveguide?

The configuration is, in one plane, what appears to be a signal trace flanked by two much larger conductors.

I have a Tektronix time domain reflectometer with P8018 (for single-ended impedance) and P80318 (for differential impedance) probes.

I called Tektronix, from which I have gotten excellent information in the past on other matters, but the technical support could not advise on this matter.

Thanks for any insight.
