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.
