M550129-03 Rev L 6-43
*CLS // clear the unit to its power-on default settings.
*RST // reset the unit.
SOUR:VOLT:PROT 4.0 // program the OVP trip point to 4.0 VDC.
SOUR:VOLT:PROT? // confirm the OVP trip point setting (response: 4.0).
SOUR:CURR 1.0 // program output current to 1.0 A.
SOUR:VOLT 3.0 // program output voltage to 3.0 VDC.
STAT:PROT:ENABLE 8 // program the unit to report OVP trip.
STAT:PROT:ENABLE? // confirm that OVP fault is enabled (response: 8).
*SRE 2 // enable the GPIB service request upon a fault.
*SRE? // confirm the GPIB service request enabled (response 2).
STAT:PROT:EVENT? // confirm no faults occurred (response: 0).
// confirm that the OVP led and SRQ led is not active.
SOUR:VOLT 7.0 // program output voltage to 7.0 VDC - cause OVP trip!
// confirm that unit issued a GPIB service request (use a serial
poll).
6.14.3 Trigger Example
Program a unit with no load at the output to change its output voltage and
current to 5 VDC @ 1A at the same time.
// 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:TRIG 1.0 // program output current to 1.0 A upon trigger.
SOUR:CURR:TRIG? // confirm output current set to 1.0 A upon trigger.
SOUR:VOLT:TRIG 5.0 // program output voltage to 5.0 VDC upon trigger
SOUR:VOLT:TRIG? // confirm output current set to 5.0 VDC upon trigger.
MEAS:CURR? // measure the actual output current (response: 0.0).
MEAS:VOLT? // measure the actual output voltage (response: 0.0).
TRIG:TYPE 3 // trigger the unit to implement curr and volt programming.
MEAS:CURR? // measure the actual output current (response: ~ 0. 0 with no
load on output).
MEAS:VOLT? // measure the actual output voltage (response: ~ 5.0).
TRIG:ABORT // turn off trigger mode.
