Applying VXI technology to DC power supply programming resistors

The legacy F-16 Analog Tester utilised resistor programmable DC power supplies for application of programmable stimulus. Resistor programmable power supplies, although still available in today's market, are becoming a rarity. The F-16 Analog Test Station Sustainment (FATSS) team decided up front to eliminate reliance on the availability of such devices, and engineer a means to convert the existing resistances to an analog voltage, more compatible with modern power supply programming options.
