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 re turne d. VOLT:TRIG? MAX
and VOLT:TRIG? MIN return the highest and lowest programmable triggered
voltage levels.
VOLTage:PROTection {<voltage>|MINimum|MAXimum}
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 page101). An overvoltage condition can be cleared
with the VOLT:PROT:CLE command after the condition that caused the OVP
trip is removed.
