Programming Voltage and Current
The following statements program both voltage and current and return the actual output from the sense terminals:
OUTP OFF | Disable the output. |
VOLT 45;CURR 25 | Program the voltage and current. |
VOLT?;CURR? | Read back the programmed levels. |
OUTP ON | Enable the output. |
MEAS:VOLT?;MEAS:CURR? | Read back the outputs from the sense terminals. |
Programming Protection Circuits
This example programs the voltage and current, programs an overvoltage protection value, and turns on the overcurrent protection. It then reads back all the programmed values.
VOLT:LEV 45;PROT 47.5 | Program the voltage and overvoltage protection. |
CURR:LEV 25;PROT:STAT ON | Program the current and overcurrent protection. |
VOLT:LEV?;PROT?;:CURR:LEV?;PROT:STAT? | Read back the programmed values. |
Note the required use of the optional LEVel header in the above example (see "The Effect of Optional Headers", given previously).
Changing Outputs by Trigger
If you do not program pending triggered levels, they default to the programmed (immediate) output levels. The following statements shows some basic trigger commands.
OUTP OFF | Disable the output. |
VOLT:LEV:IMM 22;TRIG 25 | Program the (immediate) voltage level to 22V and the pending |
| triggered level to 25 V. |
CURR:LEV:IMM I5;TRIG 25 | Program the (immediate) current level to 15 A and the pending |
| triggered level to 25 A. |
VOLT:LEV:IMM?;TRIG?;:CURR:LEV:IMM?;TRIG? | Check all the programmed values. |
OUTP ON | Enable the output. |
MEAS:VOLT?;CURR? | Read back the immediate levels from the sense terminals. |
INIT;TRIG | Arm the trigger circuit and send a single trigger. |
INIT;*TRG | Same as above, except using a common command. |
MEAS:VOLT?;CURR? | Read back the triggered levels from the sense terminals. |
If you need to send two or more triggers, program the trigger circuit for continuous arming.
OUTP OFF | Disable the output. |
VOLT:LEV:IMM 5O;TRIG 25 | Program the (immediate) voltage level to 50 V and the pending |
| triggered level to 25 V. |
INTIT:CONT ON | Program the trigger circuit for continuous arming. |
OUTP ON | Enable the output to 50 V. |
TRIG | Trigger the output voltage to 25 V. |
VOLT:TRIG 50;:TRIG | Set the pending trigger level to 50 V and trigger the output |
| voltage back to 50 V. |
INTIT:CONT OFF | Remove the continuous triggger arming. |
