In theory yes but it is the result of more than one adjustment that affects the peak from centering precisely. Some span and bandwidth settings it centers perfectly and in any case you can use the marker readout and the frequency counter readout to obtain very accurate results.
i watched with great interest, I noticed at the end that the peak was not quite centered on the gaticule. Can this be adjusted?
