Front Panel Menu Reference SCPI Command
Touch a channel to display the channel details.
In the detailed channel view, in the Output dropdown, select
Curve mode. Press the rotary knob to select.
To specify Curve mode:
CURR:MODE SAS, (@1)
l
The output is turned off when switching between Fixed mode and Curve or Table modes.
l
When switching between Fixed and Curve/Table modes, all settings will be reset (see *RST).
l
When switching between Curve and Table modes, solar array settings will be preserved.
l
The settings shown on the display are the true Vmp and Imp values. These values are calculated
based on the running curve parameters or table points.
Specify the Curve Parameters
Specify the I-V characteristic of the curve using Imp, Isc, Vmp, and Voc. These can be programmed
individually, but when programming a new curve, it is best to send all of the parameters on the same
line. This method effects an instant curve change.
The curve parameters can be entered in any order - the instrument determines if all parameters are
within acceptable limits. Any parameter not programmed retains the value of the previously
programmed curve.
Front Panel Menu Reference SCPI Command
In the Curve dialog, enter a value for each of the four
I-V curve parameters. Then press View Curve.
Specify the Imp, Isc, Vmp, and Voc on the same line:
CURR:SAS:ISC 5, (@1);IMP 4.5, (@1);:
VOLT:SAS:VOC 100, (@1);VMP 90, (@1)
l
If the curve parameters are sent individually, an error can occur if the parameter value is outside
the allowable curve characteristic determined by the three existing parameters. Additionally, it
may take up to four curve changes to obtain the final curve.
Output the Curve
To output the curve that was previously programmed:

With the correct channel selected, press the On/Off key. To run the curve on output 1:
OUTP ON, (@1)
