BM:PHASe
[SOURce:]BM:PHASe <degrees>|MIN|MAX sets the starting phase for the burst
(counted burst mode only). Select from -360 degrees to +360 degrees, in 0.001
degree increments. The default is 0 degrees.
MIN = -360 degrees. MAX = +360
degrees. [ Stored in volatile memory ]
Parameters
Comments • For sine, square, triangle, 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 point downloaded to
memory.
BM:PHASe?
[SOURce:]BM:PHASe? [MIN|MAX] queries the starting phase. Returns a value in
degrees.
BM:INTernal:RATE
[SOURce:]BM:INTernal:RATE <frequency>|MIN|MAX sets the burst rate for
internally triggered bursts (counted burst mode). The burst rate frequency defines the
interval between bursts. Select from 10 mHz to 50 kHz. The default is 100 Hz.
MIN
= 10 mHz.
MAX = 50 kHz. [ Stored in volatile memory ]
Parameters
Comments • The burst rate setting is used only when internal triggering is enabled
(triggered mode). The burst rate is ignored when single triggering or external
triggering is enabled.
• It is possible to specify a burst rate which is too fast for the function generator
to output with the specified carrier frequency and burst count. If the burst rate
is too high, the function generator will internally adjust it as needed to
continuously re-trigger the burst. The adjustment is handled internally by the
function generator (querying the burst rate returns the value specified not the
adjusted to value).
