Figure 5-12: N-Cycle burst user interface
(1) When the output signal is Sine, Square, Ramp, Pulse or Arbitrary wave
(except DC), press the front panel Mode function key ,then press the
Burst to enter the burst mode.
(2) Press , , , , or to select the bust waveform. For
example, when selecting a sine wave, press to display the burst
waveform and parameters, and change the parameters. For details,
please refer to Output Sine Wave on page 8. Press the Mode to return to
the burst mode interface.
Note: Before configuring the waveform parameters, you must first select
the channel you want to configure. Press CH1/CH2 to select the
corresponding channel, and the corresponding channel area in the user
interface will light up.
(3) Press the Cycles/Infinite softkey to hightlight Cycles, input the number of
cycles, which is the number of waveform cycles to be output for each
N-cycle pulse train. The range is from 1 to 60 000.
When Infinite is selected, the cycle number of the waveform is set as an
infinite value. The generator outputs a continuous waveform after
receiving trigger signal.
Note: In burst mode, the upper limit of the carrier frequency is half of the
max frequency of the original carrier. Taking a Sine wave as an example,
the maximum frequency is 70 MHz. Press , and set the carrier to 70
MHz, then press the Mode mode key, then press , you can see the
carrier frequency is changed to 35MHz.
Note:
⚫ If needed, Burst Period will increase to cater to the specific number of cycles.
⚫ For an infinite-cycle Burst, External or Manual Trigger is needed to activate
burst.
