What is the advantage of Write zoom over Read zoom magnification?

• A. Write zoom provides better spatial resolution
• B. Write zoom always provides a higher frame rate
• C. Write zoom reduces noise and side lobes because it is processed in memory
• D. Write zoom allows you to select a location in the image

Answer: (A)

Write zoom magnification increases spatial sampling during acquisition, so you actually collect more detail from the scene. By capturing more samples per feature, you push the system toward higher true spatial resolution, letting you distinguish smaller separations. Read zoom magnification, on the other hand, magnifies after capture by interpolating between existing samples, which does not add new information and can’t improve real resolution. The other statements don’t reflect this fundamental difference: frame rate isn’t guaranteed to be higher with write zoom, and any gains in noise or side-lobe reduction aren’t inherent benefits of writing zoom data. Selecting a location in the image is a UI feature, not the core advantage of write zoom.
