Chapter 4 Features and Functions

System-Related Operations

The name can contain up to 12 characters. The first character must be a letter (A-Z), but the remaining 11 characters can be letters, numbers (0-9), or the underscore character (“ _ ”). Blank spaces are not allowed. An error is generated if you specify a name with more than 12 characters.

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.

Front-Panel Operation:

NAME STATE , STORE STATE , RECALL STATE

After recalling a stored state, you will notice that a new choice

(UNDO RECALL) is added under RECALL STATE. This allows you to cancel the last recall operation and revert to the previous state.

You can also select LAST PWR DOWN to recall the state of the4 instrument at the power-down.

To configure the instrument to recall the power-down state or issue a Factory Reset when power is restored, select from the following.

PWR ON LAST , PWR ON RESET

Remote Interface Operation: Use the following commands to store and recall instrument states (state “0” is the state of the instrument at power down).

*SAV {012345} *RCL {012345}

To assign a name to a stored state to be recalled from the front panel, send the following command. From the remote interface, you can only recall a stored state using a number (0 through 5).

MEM:STATE:NAME 1,TEST_RACK_1

To configure the instrument to automatically issue a Factory Reset

(*RST command) when power is restored, send the following command.

MEMory:STATe:RECall:AUTO OFF
