Burst Phase
Burst phase is defined as the phase of the start point of the burst.
When Burst is enabled, press Start Phase and then use the numeric keyboard or
knob to input the desired phase, the default value is 0 ° and the available range is
from 0 ° to 360 °.
 For Sine, Square and Ramp, 0 ° is the point where the waveform passes
through 0 V (or DC offset value) positively.
 For arbitrary waveform, 0 ° is the first point of the waveform.
 For Pulse and Noise, Start Phase is unavailable.
Burst Period
Burst period is only available for N cycle burst in internal trigger and is defined as
the time from the start of a burst to the start of the next burst.
 Burst period ≥ 1μs + waveform period × number of bursts. Here, waveform
period is the period of burst function (such as Sine and Square).
 If the burst period is too short, the generator will increase this period
automatically to allow the output of the specified number of cycles.
When Burst is enabled, press Type  “N_Cyc” Source “Int”  Burst
Period and use the numeric keyboard or knob to input the desired period value.
The default is 10ms, and the available range is from 2μs to 500s.
Gated Polarity
Polarity is only available in gated burst mode. The instrument outputs burst when
the gated signal at the [Mod/FSK/Trig] connector at the rear panel is “High
Level” or “Low Level”.
When Burst is enabled, press Type  “Gated”  Polarity to select “Pos” or
“Neg”. The default is “Pos”.
