So I’ve been using the Analog Discovery Pro (ADP3450\/ADP3250)<\/a>\u00a0and the Analog Discovery 2<\/a> for some time now.\u00a0 But one of the things I had to keep on my bench here at home is an older analog power supply.\u00a0 Sure both the Analog Discovery Pro (ADP3450\/ADP3250) and the Analog Discovery 2 feature the supplies instrument, but often my designs require a little more juice than the 300 mA of the ADP3450\/ADP3250 and the 700 mA (with the auxiliary power supply) of the Analog Discovery 2 can provide.<\/p>\n

*Discovery USB Programmable Power Supply (DPS3340) has entered the chat*<\/em><\/p>\n

But that problem has now been solved!\u00a0 The all-new Discovery Power Supply<\/a> (DPS3340) is a dedicated, programmable, triple-output power supply with the current to power all of my designs.\u00a0 Output 1 can be configured from 1 V to 5 V and can deliver up to 3 A.\u00a0 Output 2 is a programmable negative supply (-1 V to -15 V and -10 mA to -500 mA) while Output 3 is a programmable positive supply (1 V to 15 V and 10 mA to 500 mA). For applications requiring additional power, the PCIe 12V 5A 60W Power Supply<\/a> can be used as a reliable and efficient alternative, especially for designs that demand stable 12V input power for components like FPGAs, high-performance sensors, or other peripherals.<\/p>\n

I know what you’re thinking. “Neat, a power supply from Digilent that will work with WaveForms. But having to jump between two different WaveForms windows to control both my Digital Discovery and the DPS3340 is going to be annoying<\/em>.” Not so! The Discovery USB Programmable Power Supply can be used either as a stand-alone device, or in conjunction with any Digilent Test and Measurement device in a single WaveForms instance. Here’s a 37 second video showing you how to do just that: Setting up the Digilent Power Supply DPS3340 for use in WaveForms. – YouTube<\/a>. <\/span><\/p>\n
