Old EOM Test

The older 3 electrode EOM has been taken apart and reassembled as part of the crystal crisis a few months back. The attached plot shows a sweep of the the reflected RF power using the 45MHz input. The resonance is still close to 45.5MHz, where we would expect it. The 43MHz needed for JAC is pretty far off resonance, also as expected. This should be no worth than what we have installed assuming the Qs are similar.
