[SOURce:]VOLTage:MODE

This command determines what happens to the output voltage during a triggered event.

FIXed	The output voltage is unaffected when a trigger occurs.
STEP	The output voltage is programmed to the value set by VOLT:TRIG when a trigger occurs.
Command Syntax		[SOURce:]VOLTage:MODE <mode>, (@<channel list>)
	Parameters	FIXed STEP
	*RST Value	FIXed
	Examples	VOLT:MODE FIX,(@1)
	Query Syntax	[SOURce:]VOLTage:MODE? (@<channel list>)
Returned Parameters		<CRD>

[SOURce:]VOLTage:PROTection:STATe

This command enables or disables the overvoltage protection (OVP) function. The command only applies in voltage priority mode. When enabled, the output of the unit will shut down and the output relays will open when the output voltage exceeds +11.5V (±0.3V), or −11.5V (±0.3V).

CAUTION: Disabling the overvoltage protection function may cause excessive output voltages, such as can occur if remote sense leads are shorted, to damage the equipment under test.

Command Syntax	[SOURce:]VOLTage:PROTection:STATe <bool>, (@<channel list>)
Parameters	0 OFF 1 ON
*RST Value	ON
Examples	VOLT:PROT:STAT 0,(@1)
Query Syntax	[SOURce:]VOLTage:PROTection:STATe? (@<channel list>)
Returned Parameters	<NR1>0 or 1
