Model Span after Mode Preset Max Span
(can't set higher than this)
CXA opt C75 1.499 GHz 1.58 GHz
MXE 1 GHz 1.000025 GHz
Note that if you are in External Mixing, the maximum Span is Maximum Stop
Frequency – Minimum Start Frequency for the currently selected mixer.
Auto Tune
This is an immediate action control. When it is pressed, it causes the instrument to
change "Center Frequency" on page 1818 to the strongest signal in the tunable
span of the instrument, excluding the LO. It is designed to quickly get you to the
most likely signal(s) of interest, with no signal analysis knowledge required. As such,
there are no configurable parameters for this feature. There are only preselected
values that work in most real-world situations.
