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 0.36 mV (E3633A) 
and 0.95 mV (E3634A) respectively. 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>|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 page 133). An overvoltage condition can be cleared 
with the 
VOLT:PROT:CLE
 command after the condition that caused the OVP trip 
is removed.
