Below are listed a few measurements I made with the experimental Direct Diode Detection Base-Band Q (3D-BBQ) Measurement in year 2004 on the PS machine. I tried to publish measurements which were taken with the same front-end gain. Unless otherwise noted, the gain was ca 60dB (minimal gain = 30dB, maximal gain = 95dB).
Some description of the PS system can be found in the first measurement section. General explanation is in the hardware page.
Do not overlook the possibility to listen to the beam!
