Front Panel Menu Reference SCPI Command
Press the Voltage key.
Enter a value and press Select.
To setthe output voltage to 40 volts:
VOLT 40
When the unit is in current priority mode, you can specify a voltage limit which limits the output voltage
at the specified value. The output current will remain at its programmed setting as long as the load
voltage remains within the voltage limit setting.
Front Panel Menu Reference SCPI Command
Press the Voltage key.
Specify a + Voltage limit. Then press Select.
To setthe voltage limit:
VOLT:LIM 42
Set the Output Current
When the unit is in voltage priority mode, you can specify a positive and negative current limit, which
limits the output current at the specified value. In voltage priority mode, the output voltage remains at
its programmed setting as long as the load current remains within its programmed positive or negative
limit.
Front Panel Menu Reference SCPI Command
Press the Current key.
Specify a positive or negative Current limit. Then press
Select.
To setthe positive current limit:
CURR:LIM 12
To setthe negative current limit:
CURR:LIM:NEG -3
When the unit is in current priority mode, you can specify a positive or negative output current level,
which will be maintained as long as the output voltage remains within its programmed limit.
Front Panel Menu Reference SCPI Command
Press the Current key.
Enter a positive or negative value. Then press Select.
To setthe output current to +5 amperes:
CURR 5
To setthe output current to –5 amperes:
CURR –5
Set the Slew Rate
The voltage slew rate determines the rate at which the voltage changes to a new programmed
setting. This applies to both voltage settings in voltage priority mode, and voltage limit settings in
current priority mode. When set to MAXimum, INFinity, or to a very large value, the slew rate will be
limited by the analog performance of the output circuit. This setting can used to prevent crossover into
current limit while up- and down-programming capacitive loads. Use the following equation to
calculate the maximum slew rate limit to ensure smooth and linear up- and down-programming
performance.
