Command Description SCPI
:TRIGgered
Sets the output voltage to ramp from the present value to
the specified value (first argument) in the specified time
(second argument) upon the trigger command. See
description of the Ramp Function below.
N
:TRIGgered? Returns the output voltage to ramp N
:TRIGgered
Sets the output voltage to the values stored by the
SOURce:VOLTage:TRIGger:AMPLitude command.
C
:TRIGgered?
Returns the voltage level that will be set upon receipt of the
trigger.
C
:CLEar
Clears the value stored by the
SOURce:VOLTage:TRIGger:AMPLitude command.
C
:AMPLitude
Stores the value of the output current to be set when the
SOURce:VOLTage:TRIGGered command is sent.
C
:AMPLitude?
Returns the stored value of the output current to be set
when the SOURce:VOLTage:TRIGGered command is sent.

6.5.3 RAMP FUNCTION
The ramp function allows the user to transition from one voltage or
current to another linearly in a specified time period (100 ms - 99 sec with
100 ms programming resolution). A unit may ramp only voltage or
current, not both at a given time.
For example, SOUR:VOLT:RAMP:TRIG 1 1 followed by
SOUR:CURR:RAMP:TRIG 2 2 will cause the unit to ramp only the output
current to 2 amps in 2 seconds upon the TRIG:RAMP command.
V OLTAGE RAMPING TO A HIGHER VOLTAGE
Requires a programmed current of at least 20% of the full scale value.
Settings less than 20% will significantly lengthen the ramp time due to
charging of the large capacitance in the output section of the power
supply.
V OLTAGE RAMPING TO A LOWER VOLTAGE
Requires an appropriate resistive load. The discharge rate of the large
capacitance in the output section of the power supply, plus other user
capacitance, significantly lengthens the ramp time.
C URRENT RAMPING
Requires an appropriate resistive load.
