Shutting Down the Instrument

Shutdown Procedure

The following GPIB command can be used to remotely shut down the E4991A. This

command cannot be used to the instrument’s power on.

• SYST:POFF on page 523

When the above command is used to shut down the E4991A, the standby switch remains

pressed, unlike when the instrument is shut down by using the standby switch on the front

panel. To turn the power on again from this state, use one of the following methods.

• Return the standby switch to the off state and then turn it on again.

• Stop supplying power to the E4991A and then supply power again. The simplest way

to do this is to unplug the power cord attached to the rear panel.

NOTE Once the above command is executed, the same shutdown process of the E4991A is

performed as when the standby switch is pressed. For details on cautions when shutting

down the instrument, refer to the Operation Manual.
