7 - Programming the DC Source
Output Voltage
The output voltage is controlled with the VOLTage command. For example, to set the output voltage to
15 volts, use:
VOLTage 15
Maximum Voltage
The maximum rms output voltage that can be programmed can be queried with:
VOLTage? MAX
Overvoltage Protection
The dc source can be programmed to turn off its output if the output voltage exceeds a preset peak
voltage limit. As explained in chapter 8, this protection feature is implemented with the following
command:
VOLTage:PROTection <n>
where <n> is the voltage protection level.
NOTE:
Use the VOLT:PROT:STAT 0 command to disable the overvoltage protection circuit if
its operation interferes with the proper operation of your phone test.
Output Current
All models have a programmable current function. The command to program the current is:
CURRent <n>
where <n> is the current limit in amperes.
If the load attempts to draw more current than the programmed limit, the output voltage is reduced to
keep the current within the limit.
Maximum Current
The maximum output current that can be programmed can be queried with:
CURRent? MAX
Overcurrent Protection
The dc source can also be programmed to turn off its output if the current limit is reached. As explained
in chapter 8, this protection feature is implemented the following command:
CURRent:PROTection:STATe
NOTE:
Use the OUTP:PROT:DEL command to prevent momentary current limit conditions
caused by programmed output changes from tripping the overcurrent protection.
