[SOURce:]OUTPut:DFI:SOURce

This command associates the DFI TTL output on the rear panel

with a specified bit in the status byte register (SBR). Once the bit is

associated with the DFI signal, the DFI signal will reflect the state of

the specified bit. The port needs to be in the DFI or RI mode before

using this command. Use the [SOURce:]DIGital:FUNCtion (on page

4-12) command to set the port mode.

*RST value is OFF.
