Select Channel
Once the offset is acquired you can write a value (in hex) to
any selected DAC register as follows:
•
to 3FFF) at DAC Word (Hex). Press Return.

3) Acquire/Readback Mode
This mode allows the user to read back the data in a particular
DAC register via the serial interface.
Acquire & Readback
Use this function to acquire VIN and read back the corre-
sponding DAC value as follows:
• Select any channel and enter the required V
at Analog Input Voltage. Press Return.
• Click on Acquire & Readback to acquire V
the DAC value in hex at DAC Code.
Readback
Use this function to readback a particular DAC as follows:

4) Calibrated/SHA Mode
This mode allows the user to determine the output range of
each channel for a particular offset value. Results can be saved
to a file and re-loaded in a later session.
Channel Calibration
