agilent infinium scope scale setting problem!!

[Edge]

I have a vi that sets the frequency on an arbitrary waveform generator and the output of that arb is connected to chan1 on the Agilent infinium scope. When the scope gets the frequency, it Autoscales and then if sets the scale to the right divisions per second on its own, now the problem I have is that if I put lets say more than 10MHz on chan1 of the scope, the Autoscale sets the Scope's scale to lets 50ms/div and I want to be able to programmatically set the scale on the scope to what I want, can someone tell me if its possible or do I have to stick with Autoscaling?

The thing is that I want to be able to read a certain voltage on the channle, lets say I want to be able to read 500mv pk-pk, if the scale of the scope
is on lets say 50ms/div, it takes longer to find the pk-pk voltage that I want and sometimes it may not find it...

Can anyone help?

You can turn autoscaling off and use the Configure Channel.vi function to set the vertical range. Autoscaling before every measurement will increase your test time and is something you might want to avoid in any case but what I don't understand is the other problem you're having with the autoscale function. If the scope is not correctly autoscaling and the signal is clipped, then you might want to talk to Agilent and see if there's something wrong with the scope.
