You should update to the most recent 2013 Version ;)

Interesting to note that Siglent has begun to post firmware updates on their web site as of April 3, 2013.  A serious customer service improvement!

commongrounder:
I am now an owner of a SDG1005.  I checked over some of the functions and immediately found what I think are a couple of bugs.  When set up in sweep mode, it appears that the LOG sweep function is not correct.  It behaves more like an exponential rise, rather than an equal power log10 low to high sweep.  The only way I can get a close approximation of the proper frequency distribution is to reverse the direction of the frequency sweep (high to low rather than low to high).
Can someone who has the Lecroy firmware on their machine check if this is true with that version as well?  A 20 second audio sweep (20hz to 20khz) works well as a test, to allow monitoring of the frequency.
Also, the DB level indication seems way low for the actual output.  An actual measured zero dbm (into a high-z input millivolt-meter) level is shown as something like -32dbm on the generator screen.  The maximum settable dbm level is -13 on channel 1, and I know the maximum open circuit voltage is 20 volts pk-pk.  Am I missing something? 
I plan to forward my concerns to Siglent.  I think this unit has the potential to be very useful, when a few of the bugs are ironed out!

nctnico:
Afaik some of these bugs are fixed in the latest firmware.

commongrounder:
Sorry, I neglected to mention that my unit is running the version....27 firmware.
