State Storage Commands

State Storage Commands

The instrument has six storage locations in non-volatile memory to store instrument states. The locations are numbered 0 through 5. The instrument uses location “0” to automatically hold the state of the instrument at power down. You can also assign a name to each of the locations (1 through 5) for use from the front panel.

*SAV {012345}

Store (save) the current instrument state in the specified storage location. Any state previously stored in the same location is overwritten (no error is generated).

∙ You can store the instrument state in any of the six locations. However, you can only recall a state from a location that contains a previously stored state. You can use location “0” to store a sixth instrument state. However, keep in mind that location “0” is automatically overwritten when power is cycled.

∙ The instrument stores the state of all modules including all channel

configurations, scanning setups, alarm values, and scaling values.

∙ A Factory Reset (*RST command) does not affect the configurations stored in memory. Once a state is stored, it remains until it is overwritten or specifically deleted.

*RCL {012345}

Recall the instrument state stored in the specified storage location. You cannot recall the instrument state from a storage location that is empty or was deleted. When shipped from the factory, storage locations “1” through “5” are empty (location “0” has the power-on state).

You can use location “0” to store a sixth instrument state. However, keep in mind that location “0” is automatically overwritten when power is cycled.

Before recalling a stored state, the instrument verifies that the same module types are installed in each slot. If a different module type is installed, the instrument will perform the equivalent of a Card Reset (SYSTem:CPON command) on that slot.
