Ramp V Example 2

Program a unit with no load at the output, to ramp its output voltage from
5 VDC to 25 VDC in 30 seconds upon the trigger command.

// Use

SYST:ERR?

after each command to verify no programming errors.

// turn on the unit.

*CLS

// clear the unit to its power-on default settings.

*RST

// reset the unit.

SOUR:CURR 33.0

// program output current to 33.0 A.

SOUR:VOLT 5.0

// program output voltage to 5.0 VDC.

SOUR:VOLT:RAMP:TRIG 25.0 30.0

// program voltage to ramp from the present

// value (5.0 VDC) to 25.0 VDC in 30 secs.

// upon the trigger command.

TRIG:RAMP

// start ramp execution.

TRIG:ABORT

// turn off trigger mode.

Power On INIT Example

Program a unit to power-on and initialize to 2 VDC @ 1A with an
overvoltage protection level of 3 VDC. Verify proper power-on
initialization.

// Use

SYST:ERR?

after each command to verify no programming errors.

// turn on the unit.

*CLS

// clear the unit to its power on default settings.

*RST

// reset the unit.

CAL:INIT:CURR 1.0

// set power-on initial current to 1.0 A.

CAL:INIT:CURR?

// confirm power-on initial current setting.

CAL:INIT:VOLT 2.0

// set power-on initial voltage to 2.0 VDC.

CAL:INIT:VOLT?

// confirm power-on initial voltage setting.

CAL:INIT:VOLT:PROT 3.0

// set power-on initial overvoltage protection to 3.0 VDC.

CAL:INIT:VOLT:PROT?

// confirm power-on initial overvoltage protection setting.

CAL:UNLOCK “6867”

// unlock nonvolatile memory for calibration value storage.

CAL:STORE

// store the calibration values in nonvolatile memory.

CAL:LOCK

// lock nonvolatile memory for calibration value protection.

// cycle power to the unit.

// note voltage is initialized to 2.0 VDC via front panel.

SOUR:CURR?

// confirm power-on initial current setting.

SOUR:VOLT?

// confirm power-on initial voltage setting.

SOUR:VOLT:PROT?

// confirm power-on initial overvoltage protection setting.
