The Discovery Power Supply (DPS3340) has 3 programmable Digital Voltage Supplies, which can supply between 0 V to +5 V, 0 V to +15 V, and 0 V to -15 V through the Power Supplies ("Supplies") instrument.

Each of the power supply rails is associated with an LED available on the connector, just above the supply's screw terminal, which is used to indicate the operating mode of that supply. When a load doesn't require more current than the supply's current limit, the supply operates in Constant Voltage (CV) mode, and the indicator LED is blue. When the load does try to draw more current than the current limit, the supply operates in Constant Current (CC) mode, and the LED is orange. WaveForms' Supplies instrument UI for the DPS3340 also features these LEDs, showing CV mode with a green indicator and CC with a red indicator.
