No, the -8DIG (8-channel digital output) option is not available for the Model 686 in the 2-channel (2C-SE/D) configuration. Digital output options on the Model 686 require a minimum of 4 analog channels, because the digital outputs are derived from the analog channel DACs. If your application requires both the Model 686’s high-speed AWG performance and digital pattern outputs, you will need to specify a 4-channel configuration. Contact Berkeley Nucleonics to discuss the right Model 686 configuration for your analog and digital channel requirements.
