HP E1340A Arming and Marker Outputs
Chapter Contents
This chapter shows you how to arm and gate the HP E1340A AFG in order
to start and advance standard and arbitrary waveforms. This chapter also
shows how generate the different marker outputs at the "Aux Out" BNC
connector. The sections of this chapter include:

The ARM Configuration
The HP E1340A AFG uses an ARM triggering configuration to output the
standard and arbitrary waveforms. When initiated, an arm signal enables the
AFG to output the waveforms each time an arm signal is received.
The ARM States The AFG operates within three states: Idle, Wait-for-arm, and Instrument
Action.
When power is applied, or following a reset or an abort, the AFG is in the
Idle state. The AFG is set to the Wait-for-arm state with the
INITiate[:IMMediate] command.
The AFG starts instrument action when it receives an arm from the
specified arm source.
After the instrument action (waveform is output) occurs, the AFG returns to
the Wait-for-arm state until the next arm occurs. When the specified arm
count has been reached, the AFG returns to the Idle state.
