SG Series Programming SCPI Command Operation
M550129-03 Rev L 6-45
// value (5.0 A) to 25.0 A in 30 seconds.
6.14.7 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.
6.14.8 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.
