Pressing the Presets/Auto-Set key opens a special
menu as shown.
Standard Preset returns the instrument
to defined settings which include full span, auto RBW, 0dBm level etc.
and which cancel more complex settings such as sweep triggering* and
vertical expansion. This is particularly useful when the instrument has
previously been used for some other purpose.
Preset is a customised version of the standard preset in which
particular settings have been redefined by the user (e.g. centre, span
and level). The user preset can also be called up automatically on
power-up as an alternative to "last used" settings.
Sweep triggering requires option U02
