Source Commands
Source commands program the voltage, current, triggered, and
protection functions.
[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude] <value>|MIN|MAX
[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude]? [MIN|MAX]
[SOURce:]CURRent[:LEVel]:TRIGgered[:AMPLitude] <value>|MIN|MAX
[SOURce:]CURRent[:LEVel]:TRIGgered[:AMPLitude]? [MIN|MAX]
These commands set the immediate and the triggered output current
level. The values are programmed in amperes. The immediate level is
the output current setting. The triggered level is a stored value that is
transferred to the output when a trigger occurs. At *RST, the
immediate and triggered current values = 0.
[SOURce:]CURRent:PROTection:STATe ON|OFF
[SOURce:]CURRent:PROTection:STATe?
This command enables or disables the over-current protection (OCP)
function. The enabled state is On (1); the disabled state is Off (0). If
the over-current protection function is enabled and the output goes
into constant current operation, the output is disabled and OC is set
in the Questionable Condition status register. The *RST value = Off.
An over-current condition can be cleared with the Output Protection
Clear command after the cause of the condition is removed.
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <value>|MIN|MAX
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude]? [MIN|MAX]
[SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPLitude] <value>|MIN|MAX
[SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPLitude]? [MIN|MAX]
These commands set the immediate and the triggered output voltage
level. The values are programmed in volts. The immediate level is the
output voltage setting. The triggered level is a stored value that is
transferred to the output when a trigger occurs. At *RST, the
immediate and triggered voltage values = 0.
The range of values that can be programmed for these commands is
coupled with the voltage protection and the voltage limit low settings.
The maximum value for the immediate and triggered voltage level is
either the value in the following table, or the voltage protection
setting divided by 1.05; whichever is lower. The minimum value is
either the value in the table, or the low voltage setting divided by
0.95; whichever is higher.
Note that triggered values can be programmed outside these limits,
but an error will be generated when the trigger occurs.
