The combination of the SIS8300-L digitizer AMC and the DWC8VM1 Rear Transition Module (RTM) can be used as single cavity Low Level Radio Frequency (LLRF) controls solution for cavities with frequencies ranging from 700 MHz to 4 GHz. A first batch of 10 DWC8VM1 modules with different frequencies was build under license of DESY and shipped in March of 2014.
SIS8300-L/DWC8VM1 combination
The DWC8VM1 has 8 downconverter channels, 2 auxiliary analog input channels and one vectormodulator channel. After the analog to digital conversion of the intermediate frequency (IF) you can handle the signal processing in the Virtex 6 of the SIS8300-L digitizer board and control the vectormodulator channel with the dual digital to analog converter. The analog signals in between of the DWC8VM1 and SIS8300-L are routed over the Zone 3 connector.
