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 0.36 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 103). An overvoltage condition can be cleared
with the
VOLT:PROT:CLE
command after the condition that caused the OVP
trip is removed.
