Preset State
When the
lpresetJ
key is pressed, the analyzer reverts to a known state called the factory preset
state. This state is defined in
‘Iable
12-3. There are subtle differences between the preset
state and the power-up state. These differences are documented in
Table
12-4. If power to
non-volatile memory is lost, the analyzer
will
have certain parameters set to default settings
‘Ihble
12-5 shows the affected parameters.
When line power is cycled, or the
Lpresqt)
key pressed, the analyzer performs a self-test routine.
Upon successful completion of that routine, the instrument state is set to the conditions shown
in
‘Ihble
12-3. The same conditions are true following a “PRES;” or “RST;” command over
HP-IB, although the self-test routines are not executed.
You also can coniigure an instrument state and define it as your user preset state:
1. Set the instrument state to your desired preset conditions.
2. Save the state (save/recall menu).
3. Rename that register to “UPRESET”.
The
w
key is now toggled to the
##$WC
selection and your defined instrument state

be
recalled each time you press

and when you turn power on. You can toggle back to the

Note
When you send a preset over HP-IB, you will always get the factory preset.
You can, however, activate the user-defined preset over HP-IB by recalling the
register in which it is stored.
