Generating 9 dc signals in the same time

[faisally]

Hi,

I'm wondering if there is a lab equipment that can generate 9 dc analog signals in the same time, I have an embedded system that should receive 9 dc analog inputs with different values in the same time.

Thank you

Hi faisally ,

surely there is such "equipment"!

Do you have any special requirements?

Start with this one…

Thank you for your help, I'll check if I can get that.

For testing purposes, you could just string a bunch of resistors in series as taps then control the voltage source to the network.

Vsupply Return<--^^^--+--^^^--+--^^^--+--  ...  --^^^--+--^^^-->Vsupply

With set resistances, all of the tap voltages will change with Vsupply as a percent of Vsupply.
