Profile Generator; Integrator - HBM SomatXR CX23-R User Manual

CX23-R and EX23-R
sawtooth wave, a duty cycle of 50 results in a triangle wave and a duty cycle of 1
results in a reverse sawtooth wave.
Period samples: Specify the number of samples that comprise one waveform
cycle. Note that the waveform frequency is the input channel sample rate divided
by the period samples.
Cycles: Specify the number of cycles to generate. After this number of cycles,
the output remains constant at the last value of the last cycle.
Scale: Specify the amplitude of the waveform.
Offset: Specify the offset of the waveform.
Drift: Specify the offset drift for each cycle. The drift value is distributed over the
cycle period for a uniform offset drift.
Decay: Specify the amplitude decay for each cycle. A decay value less than one
results in decreasing amplitudes while a decay value greater than one results in
increasing amplitudes. The decay value is distributed over the cycle period for a
uniform decay.
4.4.7 Profile generator
This computed channel is provided for HBM internal use only at this time.
4.4.8 Integrator
The Integrator computed channel generates an output that is the integral of the input
channel.
As long as the integrator is not reset or suppressed, each output sample is the
cumulative sum of the current and all previous input samples multiplied by the scale
factor and added to the initial value.
A logical trigger channel can reset the integrator or suppress integration. The
integrator can also reset when exceeding a user-defined value.
Integration parameters
Initial value: Enter the initial value for the integration.
o
Scale factor: Enter the scale factor for the integration.
o
Trigger reset options
Integrate only when true: If selected, the integration is suppressed when the
o
specified Channel is FALSE.
Enable triggered reset: If selected, the integration resets to the initial value
o
when the specified Channel meets the Reset mode condition.
Channel: Set the trigger channel used for the Integrate only when true and
o
Enable triggered reset options. This field may not be entered until at least one of
those two options is selected.
Reset mode: If the Enable triggered reset option is selected, set the condition
o
for the trigger channel to reset the integration.
When true: Reset when the trigger channel is TRUE.
o
On false - true edge: Reset when the trigger channel transitions from
o
FALSE to TRUE.
