Generating Burst Waveforms; N-Cycle Burst - Teledyne WaveStation 3000 Operator's Manual

Generating Burst Waveforms

Sine, Square, Ramp, Pulse, and Arb waveforms may utilize an N-Cycle Burst or a Gated Burst. Noise
waveforms utilize only a Gated Burst.

N-Cycle Burst

In this method, you either specify a number of cycles after which to begin the burst and its duration (period), or
set an infinite cycle and trigger the burst manually or upon an external event.
1. Generate a basic waveform
function button.
2. Press the NCycle softkey until it is selected.
3. Set the following Burst parameters:
Source - Choose Internal, External, or Manual. If you select External, connect the trigger source to the
l
Trig/Gate/Fsk/Burst connector on the Back Panel.
Start Phase - Enter a specific phase value (in °) to define the starting point of the burst. The phase
l
varies from 0° to 360°; the default setting is 0°. For an Arbitrary waveform, 0° is the first waveform
point.
Burst Period - If using Internal Source, enter the length of the burst period.
l
NOTE: The period time increases if necessary to allow the specified number of cycles in a burst. The
following formula is applied: Burst Period > Carrier Period × Burst Number.
TrigOut (Internal and Manual Sources) or Edge (External Source) - Choose Up (rising edge), Down
l
(falling edge), or Off.
Delay - Press the More softkey to display this option. Specify a span of time between the trigger
l
input and the start of the burst. The minimum delay amount is 240 ns.
Cycles or Infinite - Press the More softkey to display these options. If Cycles is selected, enter the
l
desired number of repetitions (from 1 to 1,000,000). Infinite generates a continuous waveform that
only stops upon a trigger event. Choose External or Manual Source to use Infinite.
4. When all parameters are set, press the appropriate Output button.
5. If you selected Manual source, a red Trigger option appears on the Burst menu. Press the Trigger softkey
to manually start and stop the burst as the waveform is output.
