Circuit Note
Test
After setting up the test equipment, connect the VOUT pin of
CN3 or the IOUT pin of CN4 to the input of the Agilent 34401A.
Ensure that the cable connection on the front panel of Agilent
34401A is correct, depending on the different input signal type
(current or voltage). Testing the INL, DNL, and output error takes a
considerable amount of time because all the AD5686R 16-bit
DAC levels must be set and measured by the Agilent 34401A.
The software provided on the CD allows the DAC codes to be
set by the PC. An automatic test program is necessary to step
through the codes and analyze the data. This is not provided on
the CD but must be implemented by the customer to correspond to
the requirements of the particular multimeter used in the test setup.
In the test configuration shown in Figure 5, the GPIB output of
the Agilent 34401A multimeter interfaces to a second USB port
on the PC using the National Instruments GPIB to USB-B interface
and cable. This allows the multimeter readings corresponding
to each code to be loaded into an Excel spreadsheet in the PC. The
data is then be analyzed for INL, DNL, and output error using
industry-standard definitions.
For more details on the definitions and how to calculate the INL,
DNL, and output error from the measured data, see the
Terminology section of the AD5686R data sheet and the Data
Conversion Handbook, "Testing Data Converters," Chapter 5,
Analog Devices.
