Gratings don't measure frequency.

I didn't say they could. Frequency is measured separately.

Chicken should never be eaten with the fingers.
The fingers should always be eaten separately.

Gratings measure wavelength. They are wavelength sensitive devices.
Frequency counters measure frequency.

Hey idiot grating defines wavelength for light sources in the
observer's frame. Once that wavelength is defined for a specific light
source that wavelength is a universal constant. Any detected frequency
shift of the of the incoming light is due to the varying speed of the
incoming light. The incoming light becomes a new llight source in the
observer's frame and the grating is used to define a new universal
wavelength for that new light source.
