VOLTage:STEP {<numeric value> | DEFault}
Set the step size for voltage programming with the VOLT UP and VOLT DOWN
commands. See the example below.
To set the step size to the minimum resolution, set the step size to ‘‘DEFault’’.
The minimum resolution of the step size is approximately 0.35 mV (E3640A),
1.14 mV (E3641A), 0.38 mV (E3642A), 1.14 mV (E3643A), 0.35 mV (E3644A),
and 1.14mV (E3645A), respectively. 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. At *RST, the step size is the
value of the minimum resolution.
VOLTage:STEP? [DEFault]
Return 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.
Example The following program segments show how to use the VOLT UP or VOLT DOWN
command to increase or decrease the output voltage with the VOLT:STEP
command.
‘‘VOLT:STEP 0.01’’ Set the step size to 0.01 V
‘‘VOLT UP’’ Increase the output voltage
‘‘VOLT:STEP 0.02’’ Set the step size to 0.02 V
‘‘VOLT DOWN’’ Decrease the output voltage
VOLTage:TRIGgered {<voltage>| MINimum | MAXimum}
Program 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]
Query the triggered voltage level presently programmed. If no triggered level
is programmed, the VOLT level is returned.
VOLTage:PROTection {<voltage>|MINimum|MAXimum}
Set 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. An overvoltage condition can be cleared with
the VOLT:PROT:CLE command after the condition that caused the OVP trip
is removed.
