AG5 with UltraDAS + SDSU Gen.2

NB these figures refer to AG5 when it was used with a Gen. 2 controller. Converted to Gen. 3 on the 29th May 2007

Device Identification

Standard AG5 performance shown below. If the AG5 head is used with a shorter cable and started up under uDAS as AG5XF  then much faster performance is possible. This could be useful for fast photometry observations.
