General Settings
The General Settings screen lets you control functions that affect all channels of the Model 725.
To reach this screen, click the General Settings button, or choose Channel>General.
Disable/Enable I/O
On occasion you will need to abort an experiment or quickly place all outputs to your equipment
in a “safe” state. Each of the tabs of the General Settings screen includes buttons that let you
“disable” and “enable” all inputs and outputs to the Model 725. With I/O disabled, input signals
are ignored. Each output will be held at either a logic low or logic high, depending upon its
channel properties. We’ll refer to the “safe” voltage that a channel produces when disabled as the
“quiescent state” (see Channel Properties: Quiescent States). To restore channels functions, click
the Enable I/O button. These functions are nonvolatile: the enabled and disabled states are
restored on power cycle.
You can also disable or enable inputs and outputs from the Model 725 front panel (see
Experimenting: Disable/Enable All).
