Agilent Technologies E1441A user service BM:PHASe?, BM:INTernal:RATE, Parameters

BM:PHASe

[SOURce:]BM:PHASe <degrees>MINMAX 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

Parameter Name	Parameter Type	Range of Values	Default Units
degrees	numeric	-360 to +360	degrees

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? [MINMAX] queries the starting phase. Returns a value in degrees.

BM:INTernal:RATE

[SOURce:]BM:INTernal:RATE <frequency>MINMAX 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

Parameter Name	Parameter Type	Range of Values	Default Units
frequency	numeric	10E-03 to 50E+03	Hz

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).
