Output Voltage; Output Current - Agilent Technologies 66111A User Manual

7 - Programming the DC Source

Output Voltage

The output voltage is controlled with the VOLTage command. To set the output voltage to 5 volts, use:
or
VOLT 5
for models that have a second output
VOLT2 5
Maximum Voltage
The maximum output voltage that can be programmed can be queried with:
VOLT? 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:
VOLT:PROT <n>
NOTE: Use the VOLTage:PROTection:STATe 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:
<n> or
CURR
CURR2 <n> for models that have a second output
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:
CURR? 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:
CURR:PROT:STAT
NOTE:
Use the OUTPut:PROTection:DELay command to prevent momentary current limit
conditions caused by programmed output changes from tripping the overcurrent
protection.
