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