The new 2L2H DBBC3 backend also participated in the observations. The firmware DDC_E_v126 was used. The frequency setup was set by FS instead of the DBBC3 configuration files. So, the firmware was not re- loaded before the observations. To support the rapid fringe tests with SFXC, we used two 128 MHz filters (RCP: BBC01 USB, Thread 0; LCP: BBC09 USB, Thread 1) and recorded the two-thread VDIF data as a single file for each scan.
