:SAVE

:SAVE

Syntax

MEMory:SAVE

Description

This command copies the RAM image to the EEROM. Care should be taken to do this only when necessary, due to the limited life of the EEROM. (Refer to DIAG:EEROM:CYCLES?). Because this is time consuming (over a minute in some cases), it is made to turn on the “switching” light while saving. The CALIBRATING bit in the OPER status register is set when a save begins and cleared when it ends. *OPC can also be used to detect the end of a save.

The following data will be saved:

the VERIFY list

the DRIVE list

the PFAIL list

the serial number and model number

the WIDTH and DELAY times for all switches

all GROUP data, including group names, titles, AUTOSELECT state

what PATHs are in each group

all PATH data, including path names, titles, and values

what channels are in each PATH

In addition, in the “last state” list will be saved:

the current state of all switches in the DRIVE list

the programmed state of all switches not in the DRIVE list

If you know that you have performed a valid SAVE to the EEROM (one that was not interrupted by turning off power and which did not generate an error), and you subsequently get an EEROM invalid error message, you should replace the EEROM.
