Burst Phase

The burst phase defines the starting phase of the burst.
• Burst phase: -360 degrees to +360 degrees. The default is 0 degrees.
• From the remote interface, you can set the starting phase in degrees
or radians using the UNIT:ANGL command (see page 228).
• From the front panel, the starting phase is always displayed in degrees
(radians are not available). If you set the starting phase in radians
from the remote interface and then return to front-panel operation,
you will see that the function generator converts the phase to degrees.
• For sine, square, and ramp waveforms, 0 degrees is the point at which
the waveform crosses zero volts (or the dc offset value) in a positive-
going direction. For arbitrary waveforms, 0 degrees is the first
waveform point downloaded to memory. The burst phase has no effect
on pulse or noise waveforms.
• The burst phase is also used in the gated burst mode. When the gate
signal goes false, the current waveform cycle is completed and then
the function generator stops. The output will remain at the voltage
level corresponding to the starting burst phase.
• Front-Panel Operation: To set the burst phase, press the Start Phase
softkey and then use the knob or numeric keypad to enter the desired
phase in degrees.
• Remote Interface Operation:
