Channel 8	`DAS #2 IFP#2-HI 1682 - 1698 MHz USB LCP`
DAS 1 Skyfreq	1650.00 MHz
DAS 2 Skyfreq	1682.00 MHz
Bandwidth	16 MHz
DAS Mode	vsop.pro (telescope)

Please note disks recorded in observatory links below

Connect DAS to VSIC using “Huygens” Cable
Both DAS units are used to give 2 x 256 Mbps = 512 Mbps recording over 8 x 16 MHz channels
DAS#2 should be configured to be the higher frequency and connected to input#2 (input with clock lines connected).

Connect DAS directly to VSIC
One DAS unit is used to give 1 x 256 Mbps recording over 4 x 16 MHz channels.
Record LCP only, matching the four LCP bands shown above. This setup will require splitting the RF signal and setting up two IF chains, one into each IFP of the DAS.
