HP 8753E manual Preset State, Register in which it is stored

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 wilI be recalled each time you press m and when you turn power on. You can toggle back to the

factory preset hstment *ateby pressing= ad selecting ~~~~~~~.

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.
