AS 90MHz re-attenuated

[Jenne, Sheila]

We measured the drive to the 90MHz distribution amplifier, and gave it a 2dB attenuator so that we are now driving the distribution amp with 10dBm rather than 12dBm.  We re-measured the outputs of the distribution amplifier, and now they were a little over 12dBm.  So, each output of the distribution amplifier got a 2dB attenuator, so each of the demod boards is getting the 10dBm that they want for their local oscillators.
