Burst Delay

Burst delay, which is only available for N-Cycle Burst mode, is the duration from the
time when the instrument receives the trigger signal to the time when it starts to
output the burst signal.
Click or tap the Delay input field and use the pop-up numeric keypad to set the delay.
The default delay is 0 s and the resolution is 0.1 ns. The range of burst delay is related
to the trigger source:
• Manual/external trigger: 0 s to 20 s.
• Internal trigger: 0 s to (
than or equal to 20 s.

Burst Phase

In Burst mode, the fundamental phase is no longer in effect. The phase characteristics
are determined by the burst phase. When the burst type is set to "NCycle", click or
tap the Phase input field to set the burst phase. When the burst type is set to
"Gated", click or tap the Start Phase input field to set the phase. It ranges from -360°
to 360°, and the default is 0°. The resolution is 0.01°.
• For Sine, Square, and Ramp, 0° is the point at which the waveform crosses 0 V
(or DC offset) in a positive-going direction.
• Burst phase setting is not available for noise.
• For arbitrary waveforms, 0° is the first waveform point.
TIP
In Burst mode, the fundamental phase is fixed to 0° and cannot be modified.
