Output Setting and Operation Commands

VOLTage:STEP {<numeric value>DEFault}

This command sets the step size for voltage programming with the VOLT UP and VOLT DOWN commands. See the above example in the previous page.

To set the step size to the minimum resolution, set the step size to ‘‘DEFault’’. The minimum resolution of the step size is approximately 0.55 mV. The VOLT:STEP? DEF returns the minimum resolution of your instrument. The immediate voltage level increases or decreases by the value of the step size. For example, the output voltage will increase or decrease 10 mV if the step size is 0.01.

This command is useful when you program the power supply to the allowed minimum resolution. At *RST, the step size is the value of the minimum resolution.

VOLTage:STEP? {DEFault}

This query returns the value of the step size currently specified. The returned parameter is a numeric value. ‘‘DEFault’’ gives the minimum resolution step size in unit of volts.

VOLTage:TRIGgered {<voltage> MINimum MAXimum}

This command programs the pending triggered voltage level. The pending triggered voltage level is a stored value that is transferred to the output terminals when a trigger occurs. A pending triggered level is not affected by subsequent VOLTage commands.

VOLTage:TRIGgered? [MINimum MAXimum]

This query returns the triggered voltage level presently programmed. If no triggered level is programmed, the VOLT level is returned. VOLT:TRIG? MAX and VOLT:TRIG? MIN return the highest and lowest programmable triggered voltage levels.

VOLTage:PROTection {<voltage>MINimumMAXimum}

This command sets the voltage level at which the overvoltage protection (OVP) circuit will trip. If the peak output voltage exceeds the OVP level, then the power supply output is shorted by an internal SCR. The Questionable Status register ‘‘OV’’ bit is set (see page 101). An overvoltage condition can be cleared with the VOLT:PROT:CLE command after the condition that caused the OVP trip is removed.
