Period
Set the waveform period in terms of the number of samples. The waveform frequency
(in Hz) is defined as the sample rate divided by the period. For example, a period of
100 samples at a sample rate of 1000 results in a 10 Hz signal.
Duty Cycle
Set duty cycle in percent for triangle and square waveforms modes only. The default
value of 50% produces symmetric waveform shapes. Assuming the signal has not
been inverted, the duty cycle represents the percentage of time that the square
waveform is in the low state or the percentage of time that the triangle waveform is in
the ramp up state.
Cycles
Set the value used to define the number of continuous cycles (i.e., passes through the
file) to output. After the outputting the specified number of cycles, the eDAQ
lite
repeatedly outputs the last data value in the file.
Scale
Set the value used to scale the data values as defined in the file on a point-by-point
basis.
Offset
Set the value used to offset the data values as defined in the file on a point-by-point
basis.
Decay
Set the value used to adjust the scale value on a pass by pass basis. The scale factor
is multiplied by the decay factor on each successive pass, which results in an
exponential decay of the signal if the decay factor is a positive fraction. Note that the
default value of one results in a consistent signal from pass to pass with no decay.
Drift
Set the value used to adjust the offset value on a pass by pass basis. The drift factor
is added to the offset value on each successive pass. Note that the default value of
zero results in a consistent signal from pass to pass with no drift.
6.8.3 Simulation Message
Output Data Type
The output data type is always 8-bit unsigned message.
Format
Select either an ASCII or binary message format. The ASCII format pouts a repeating
pattern of the 26 letters from A to Z. The binary format outputs a repeating pattern of
byte values from 0 to 255.
Message Size
Specify the message size in bytes.
Message Interval
Specify the period in seconds for repetitive generation of the simulated message.
