3-108

:LIMit:STATe

:SOURce:VOLTage:LIMit:STATe Control voltage limit

Parameters = 0 or OFF Disable voltage limit

1 or ON Enable voltage limit

Query :STATe? Query state of voltage limit

Description This command is used to enable or disable voltage limit. When enabled, the programmed volt-

age limit is in effect. When disabled, voltage limit is determined by the selected range.

Attempts to enable voltage limit when the present V-Source level (amplitude) exceeds the limit

value will generate a settings conﬂict error.

:MCONnect

:SOURce:VOLTage:MCONnect Control LO connection

Parameters = ON or 1 Enable LO connection

OFF or 0 Disable LO connection

Query :MCONnect? Query LO connection

Description This command is used to control the internal V-Source LO to Ammeter LO connection. When

enabled, V-Source LO is connected to Ammeter LO. This connection simpliﬁes the connection

requirements for ohms measurements and source voltage measure current measurements. When

disabled, this connection is broken.

:CURRent Commands

:RLIMit:STATe

:SOURce:CURRent:RLIMit:STATe Control resistance current limit

Parameters = 0 or OFF Disable resistance current limit

1 or ON Enable resistance current limit

Query :STATe? Query state of resistance current limit

Description This command is used to enable or disable resistance current limit for the V-Source. When en-

abled, a 1MΩ resistor is placed in series with the HI V-SOURCE OUT lead to extend the current

limit capabilities of the V-Source. When disabled, normal current limit occurs at 1mA.

:LIMit[:STATe]?

:SOURce:CURRent:LIMit[:STATe]? Query current compliance.

This command is used to determine if the V-Source has reached its current compliance limit of

1mA. The response message is explained as follows:

0 = Current compliance not reached

1 = Current compliance reached
