DriverLINX Calibration and Test Utilities
You can test the function of your DDA-08/16 board by updating an
analog output channel with a specified value using DriverLINX.
To test a DDA-08/16 board, perform the following steps:
1. From the DriverLINX DDA-08/16 Calibration and Test Setup panel,
click the Test button to display the Test Panel.
2. On the Test Panel, select the channel to test.
3. Specify the raw count equivalent of the output voltage (or current) for
each channel you want to update by entering the output value in the
binary code text box. As soon as you enter a new value, the analog
output channel is immediately updated with the new value.
4. Follow the instructions in the right frames to measure the output.
5. Repeat steps 2 to 4 to test other channels.
6. Click the Back button to return to the Setup Panel or to exit the
program.
Raw count values are between 0 and 4095. The value of a count value
depends on the output range:
●
For bipolar voltage output, a value of 0 corresponds to negative full
scale, a value of 2048 corresponds to 0V, and a value of 4095
corresponds to positive full scale.
●
For unipolar voltage output, a value of 0 corresponds to 0V and a
value of 4095 corresponds to positive full scale.
●
For current output, a value of 0 corresponds to 4mA and a value of
4095 corresponds to 20mA.
