Waveform type
Characteristics Description
Standard A waveform is selected from a built-in library. The standard waveform parameters are
programmable.
Arbitrary Arbitrary waveform coordinates are downloaded and stored in memory segments. The
arbitrary waveform parameters are programmable.
Sequenced Arbitrary waveforms are downloaded and stored in memory segments. The segments
are arranged in a sequence table that step, loop, jump and nest on segments in a user-
defined configuration. Conditional jump and nest pending an event signal.
Advanced sequences Same functionality as described for sequenced waveforms except sequences are arranged
in the sequence table.
Modulated A modulated waveform is calculated from a built-in library of modulation schemes.
Pulse A pulse waveform is calculated and downloaded to the arbitrary waveform memory.
Run mode
Characteristics Description
Continuous
Self armed
A selected output function shape is output continuously. No start commands are
required to generate waveforms.
Armed No start commands are required to generate waveforms.
Triggered A trigger signal activates a single-shot or counted burst of output waveforms and then
the instrument waits for the next trigger signal.
Normal mode The first trigger signal activates the output; consecutive triggers are ignored for the
duration of the output waveform.
Override mode The first trigger signal activates the output; consecutive triggers restart the output
waveform whether the current waveform has been completed or not.
Gated A waveform is output when a gate signal is asserted. The waveform is repeated until
the gate signal is de-asserted. Last period is always completed.
Standard waveforms
Characteristics Description
General Waveforms are computed and generated every time a standard waveform is selected.
Standard waveform library Built-in, auto computed waveforms: sine, triangle, square, ramp, pulse, sink,
exponential rise, exponential decay, Gaussian, noise and DC.
Standard waveform control The standard waveform parameters can be adjusted to specific requirements. The
waveform is recomputed with each parameter change.
