NOTE
When using a Time History DataMode to enable plotting in Infield, ensure that the
Time History sample rate is higher than the camera frame rate. For the maximum
frame rate of 30 Hz, the Time History sample rate must be at least 100 Hz and is
recommended to be 500 Hz or higher.
6.8 Simulation Input Channels
Use a simulation transducer to simulate transducer input into the eDAQ lite . This type
of transducer is independent of the signal conditioning hardware on the eDAQ
lite
.
Simulation transducers are used extensively in the product development cycle at
HBM, primarily to test computed channel and DataMode functionality. There are two
types of simulation transducers available.
NOTE
The full-scale min and max values are required only if the simulation transducer data
is stored in an integer format DataMode (i.e., 16-bit or 8-bit storage modes).
6.8.1 Simulation File
The file-based simulation transducer provides the capability to simulate input based
on an ASCII file definition of the data stream allowing completely arbitrary input data
streams. Because TCE reads the ASCII file using a C
fscanf()
function in float
format, the data entries must be separated by white space only. There is no limit on
the number of points, however be aware that the data points are stored in the
eDAQ
lite
RAM disk consuming data storage memory.
Example Simulation Files
The following examples define the same data stream but use white space differently.
Example 1:
-100.0 500.0 -700.0 300.0
Example 2:
-100.0
500.0
-700.0
300.0
Output Data Type
Select an output data type of 8-bit integer, 16-bit integer or 32-bit float.
