Is there a way for the generator to force an external reference (and never change to the internal reference)?
Currently, the frequency reference is switched to internal (with no indication on the GUI) when the frequency reference is turned off. It's too easy to continue using it thinking that the frequency is still locked (and yielding bad data).
Also, I'm worried that when it defaults to internal reference, it is outputting 10 MHz on it's reference output which is directly connected to another instrument's 10 MHz out. Having two instruments outputting 10 MHz into eachother can't be a good thing. I don't know if the hardware supports it, but it'd be nice to tell it to disable the 10MHz output while using the internal reference.
There are a few parameters (like reference mode, screensaver, language, number format, and beeper) that I'd really like to always have saved (irrespective of the "power-on setting"). Maybe as a work-around, there could be an option to load a particular saved configuration on startup(so the choices would be factory default, particular configuration, or last configuration)?
