RAMP FUNCTION

9.5.3
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.
9.5.3.1 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.
9.5.3.2 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.
9.5.3.3 C
URRENT RAMPING
Requires an appropriate resistive load.
