Signal.SetAcquisitionControl()
Signal.SetAcquisitionControl()
Type: INSTANCE FUNCTION
Purpose: To allow the user to specify specific data-acquisition parameters.
This instance function is available for all signals.
Usage: Signal.SetAcquisitionControl (AcqMode, AcqBasePeriod, SampleRate, DutyCycle)
AcqMode | INDEX |
Type of acquisition mode: 0 = Fast Mode 1 = DSP Mode |
|
or | |||
NIL |
Use the default AcqMode. This mode is set based on the output point sample period: Below 100.0 µs the system uses Fast Mode. At or above 100.0 µs, the system uses DSP Mode. |
||
AcquBasePeriod | REAL | The time between each sample point. This number should not be less than the default of 16.666 µs. | |
or | |||
NIL |
Use the default AcqBasePeriod. For ACQ_MODE_FAST, this is not used. For ACQ_MODE_DSP, the default is 16.666 µs. |
||
SampleRate | REAL | The output point rate, in seconds. Output points are the points displayed to the user and saved to the curve. They are made up of one or more sample points. | |
or | |||
NIL | Use the default sample rate specified in the SIGNAL.New call. | ||
DutyCycle | REAL | A number between from 0.0 to 1.0 specifying the duty cycle that is used in sampling. 0.0 always gives one sample, while 1.0 samples as quickly as possible. | |
or | |||
INDEX |
0 = One sample only (duty cycle of 0.0) 1 = Use the default duty cycle of 0.20 2 = Use a duty cycle of 1.0 |
||
or | |||
NIL | Use the default duty cycle of 0.20 |
NOTE: For a PCI4 family potentiostat the parameters are ignored. Only the Fast Mode is available.
