3.22.14 RS-232 Interface Commands

The following commands are provided for control (enabled or disabled) of front panel keys

while using the RS-232 interface.

:LOCal

:SYSTem:LOCal Take 6517A out of remote

Description Normally, the Model 6517A is in local during RS-232 communications. In this state, front panel

keys are operational. However, the user may wish to lock out front keys during RS-232 commu-

nications (see :LLOCkout).

This action command is used to take the Model 6517A out of the remote state and enables the

operation of front panel keys. Note that this command can only be sent over the RS-232 interface.

:REMote

:SYSTem:REMote Place the Model 6517A in remote

Description This action command is used to place the Model 6517A in the remote state. In remote, the front

panel keys will be locked out if local lockout is enabled (see :LLOCkout). Note that this com-

mand can only be sent over the RS-232 interface.

:LLOCkout <b>

:SYSTem:LLOCkout <b> Enable or disable front panel keys

Parameters <b> = 0 or OFF Disable local lockout

1 or ON Enable local lockout

Query :LLOCkout? Query state of local lockout

Description This command is used to enable or disable local lockout. If enabled, the front panel keys are

locked out (non-operational) when the instrument is in remote (see :REMote). If disabled, the

front panel keys are operational in remote. The instrument must be in remote in order to use this

command.

Taking the instrument out of remote (see :LOCal) restores front panel keys operation, but does

not change the status of the :LLOCkout command.

Note that this command can only be sent over the RS-232 interface.

3.22.15 Basic Trigger Commands

The following commands are used to conﬁgure the Model 6517A for basic triggering. See para-

graph 2.15 for details on basic triggering.

[:EXECute]

:SYSTem:MACRo:TRIGger:MODE <name> Specify trigger mode

Description When this action command is sent, the instrument will exit from advanced triggering and select

basic triggering. Sending this command while already in basic triggering has no effect on the

instrument.

:MODE <name>

:SYSTem:MACRo:TRIGger{:EXECute] Select basic triggering
