Hardware State Diagram
The following diagram shows the hardware states of the signal generator.
The signal generator can be in one of the following six basic states during
the course of operation.
Idle
—The device is not generating a waveform. All session properties or
attributes can be programmed in the Idle state. In the Idle state, the
properties or attributes have not necessarily been applied to hardware, so
the hardware configuration of the device may not match the session
property or attribute values. The device remains configured as it was the
last time a session was committed. If the computer has just been powered
on, reset, or the niFgen Reset Device VI or the
niFgen_ResetDevice
function has just been called, the device is in the default hardware state.
