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.
