HoWei Posted July 16, 2019 Share Posted July 16, 2019 I am able to programm the voltage to 1.8V, but whenever the instrument is reset the voltage is back at 3.3V. I need to set it permanently to 1.8V to not destroy/degrade my DUT, which has 1.8V digital inputs only. Is it possible to set the default output voltage to 1.8V permanently?

attila Posted July 16, 2019 Share Posted July 16, 2019 Hi @HoWei The default 3.3V can't be changed, but by default the VIO output is disabled and the DIOs are in high impedance, so no voltage is output. In your application after opening the device first adjust the digital voltage. This before enabling the VIO output or setting DIO outputs.

Question

I am able to programm the voltage to 1.8V, but whenever the instrument is reset the voltage is back at 3.3V.
I need to set it permanently to 1.8V to not destroy/degrade my DUT, which has 1.8V digital inputs only.
Is it possible to set the default output voltage to 1.8V permanently?
