The SDG7000A provides 16 digital signal outputs. The digital output function is available with the optional digital output kit. There are two digital levels to choose from: LVTTL and LVDS. The LVTTL kit output converts the LVDS signal output by the device into LVTTL signals and outputs it. Since the level conversion requires a special chip, the kit needs an external USB power supply. The kit providing LVDS output directly leads out the LVDS signal of the device without an external power supply.

The digital outputs are obtained by plugging in a matching Digital Bus Kit (LVDS or LVTTL). The Digital Bus Kit for LVDS output is passive and requires no power supply. The Digital Bus Kit for LVTTL output is active and requires a 5V power supply from the USB Host to transfer signals’ level from LVDS level to LVTTL level.
