Output Setting and Operation Commands
This section describes low-level commands used to program the power supply.
Although the APPLy command provides the most straightforward method to
program the power supply, the low-level output setting commands give you more
flexibility to change the individual parameters.
CURRent{<current>|MINimum|MAXimum|UP|DOWN}
This command programs the immediate current level of the power supply. The
immediate level is the current value of the output terminals.
The CURRent
command changes the output of the power supply to the newly
programmed value regardless of the output range presently selected.
You can substitute MINimum or MAXimum in place of a specific value for the
current parameter. MIN selects the lowest current values of 0 A. MAX selects
the highest current values allowed for the selected range.
This command also increases or decreases the immediate current level using
the UP or DOWN parameter by a predetermined amount. The command
CURRent:STEP sets the amount of increment or decrement. Notice that a new
increment setting will cause an execution error -222 (Data out of range) when
the maximum or the minimum rated current is exceeded.
CURRent? [MINimum|MAXimum]
Return the presently programmed current level of the power supply. CURR?
MAX and CURR? MIN return the highest and lowest programmable current
levels for the selected range.
CURRent:STEP {<numeric value>|DEFault}
Set the step size for current programming with the CURRent UP and CURRent
DOWN commands. See the example as shown in “Example” on page 111
To set the step size to the minimum resolution, set the step size to DEFault.
The minimum resolution of the step size is approximately 0.052 mA (E3646A),
0.014 mA (E3647A), 0.095 mA (E3648A), and 0.027 mA (E3649A), respectively.
