BURSt:NCYCles {<# cycles>|INFinity|MINimum|MAXimum}
BURSt:NCYCles? [MINimum|MAXimum]
Set the number of cycles to be output per burst (
triggered burst mode only
).
Select from 1 cycle to 50,000 cycles, in 1 cycle increments (see the
restrictions below). The default is 1 cycle. MIN = 1 cycle. MAX = based on
the burst period and frequency as shown below. Select INF to generate a
continuous burst waveform. The :NCYC? query returns the burst count
from 1 to 50,000 or “9.9E+37” (for an infinite count).
•
If the
Immediate
trigger source is selected (
TRIG:SOUR IMM
command
),
the burst count must be less than the product of the maximum burst
period and the waveform frequency as shown below.
Burst Count < Maximum Burst Period X Waveform Frequency
• The function generator will automatically increase the burst period
up to its maximum value to accommodate the specified burst count
(but the waveform frequency will not be changed). From the remote
interface, a “Settings conflict” error will be generated and the burst
period will be adjusted as described.
• For sine and square waveforms, frequencies above 6 MHz are allowed
only with an “infinite” burst count.
•When the gated burst mode is selected, the burst count is ignored.
However, if you change the burst count while in the gated mode,
the function generator remembers the new count and will use it when
the triggered mode is selected.
