NCycle/Gated - Press this operation button to select either NCycle or
Gated for your burst waveform(s). Many controls on the Burst operation
menu change based on the selection made on this control. When NCycle
is selected, you can press the Period operation button and provide a
specific value for the Pulse Period control using the detail dialog.
NOTE: The period time increases if necessary to allow the specified number of
cycles in a burst. The formula applied to this control is:
Burst Period x Carrier Period x Burst Number
N-Cycle has a specific number of waveform cycles and every burst is activated
by a trigger event, whereas a Gated burst is activated by an external source.
Source - This control is only available when NCycle is selected from the
third operation button. Select Internal, External, or Manual. If External
is selected, use the Trig/Gate/Fsk/Burst connector on the Back Panel.
You can also select Manual and specify exact start and stop times.
TrigOut - This control is only available when NCycle is selected from the
third operation button. Select Off, rising edge (↑), or falling edge (↓) as
desired.
Cycles/Infinite - This control is only available when NCycle is selected
from the third operation button. Press this operation button to highlight
and select either Cycles or Infinite amounts for your burst waveform(s).
With Cycle selected, provide a desired amount of repetitions (from 1 to
50,000) using the detail dialog. Infinite generates a continuous
waveform that only stops on a trigger event.
NOTE: The period time increases if necessary to allow the specified number of
cycles in a burst as previously mentioned in the NCycle/Gated bullet. An
external or manual trigger is required in order to activate an infinite burst.
Delay - This control is only available when NCycle is selected from the
third operation button. With Delay selected, you can specify a span of
time between the trigger input and the start of the N-Cycle burst using
the detail dialog. The minimum delay amount is 240 ns.
Polarity - This control is only available when Gated is selected from the
third operation button. Press this operation button to select either
Positive or Negative polarity for your gated signal.
