The magnetic field gradients as well as the harmonics of two 4Ql20 quadrupoles were measured utilizing a rotating coil system at Fermilab`s MTF. One magnet was from the 1975 Series, and another from the TeV II Series. For excitation currents where the remnant field is a small fraction of the total, values of the absolute gradient for the latter magnets are typically 2% lower. Among the harmonics, the skew sextupole component has the highest value for both magnets. The harmonic measurements show small differences between the ``power`` and``return`` ends of the magnet.
