Jeff, My 5370A manual calls for 9x9 & the rest XXX in the test you describe. My unit reads 10x9 for the same test. You might be in need of a full calibration, but beware of the peculiarities of the test equipment required & the need to verify all of it is in cal. It would be interesting to see what a few other folks read for the same test.
