Turns the VXG on or off. The top green LED, when lit, indicates power is on and the system is either booting up or is ready for use. The bottom yellow LED, when lit, indicates the instrument is in standby mode and connected to line power. The yellow LED remains lit while the green LED is lit.

SYSTem:PDOWn NORMal|FORCe |
SCPI Example |
:SYST:PDOW NORM ! Executes a shutdown |
Initial S/W Revision |
A.01.00 |
The front-panel button is a standby switch, not a line switch that disconnects the instrument. The instrument continues to draw power even when the front-panel switch is in standby.
The power cord on the rear of the instrument must be unplugged to disconnect line power and terminate standby mode.
Restart Application (Application Shutdown)
Remote command only.
Restarts the instrument application without rebooting the instrument. Before you send this command, make sure you have saved any data that you want to preserve.
SCPI Command |
:SYSTem:PUP:PROCess |
SCPI Example |
:SYST:PUP:PROC ! You must Wait after this command for the instrument application to restart |
Notes |
You cannot use *WAI or *OPC? to synchronize operation after a restart. This command stops and restarts the instrument application, thus the SCPI operation is terminated and restarted. A remote program must use a fixed wait time to resume sending commands to the instrument. The wait time will be dependent upon which applications are pre-loaded. |

For M9383B, M9384B and M9484C:
Remote command only.
Provides a means to terminate all open Windows applications and log off the current user. This is equivalent to performing the Windows command "shutdown –l –f –t0".
SCPI Command |
SYSTem:LOFF |
SCPI Example |
SYST:LOFF |
Notes |
This initiates an immediate log off of the current user. You cannot use *WAI or *OPC? to synchronize operation. In addition to the instrument application, all other Windows programs will be terminated without the opportunity to save any work in progress. The instrument will require human interaction to perform a Log In to regain instrument operation. |
Initial S/W Revision |
A.01.00 |
Remote command only.
For M9383B, M9384B and M9484C:
This command provides the ability to reboot the instrument. By default, the command executes a Windows Restart. Windows Restart by itself does not bring down the instrument’s power supplies. Therefore, a selection is provided to cycle power during the shutdown and restart process.
GUI Location |
Windows Start Menu > Power > Restart |
SCPI Command |
:SYSTem:REBoot [NORMal]|CPOWer |
SCPI Example |
:SYST:REB ! Executes a shutdown and reboot |
Notes |
You cannot use *WAI or *OPC? to synchronize operation after a restart. This command stops and restarts the instrument application, thus the SCPI operation is terminated and restarted. A remote program must use fixed wait time to resume sending commands to the instrument. The wait time will be dependent upon which applications are pre-loaded. The CPOWer parameter performs programmatic power cycling. If the BIOS of the controller does not support programmatic power cycling the error +617,"Configuration Error; BIOS doesn’t support cycling power" |
