For any receive signal path models inserted, the modified samples

can be accessed using Python or MATLAB®, or viewed using the

IIO Oscilloscope software.

COMMON VARIATIONS

Variations are possible on both the data acquisition and signal

generation board and AFE board. For variations on the signal

acquisition and generation paths, refer to the CN0585 circuit note.

The CN0584 allows a wide array of variations to tailor functional-

ity to a specific application. A non-exhaustive set of examples

is provided, but many additional possibilities exist and can be

implemented to create any desired setup for HIL testing or other

applications.

Bypassing the ADA4898 input buffer amplifier is possible for ap-

plications not requiring high input impedance. For higher speed

applications where amplifier bandwidth is critical and slightly higher

noise can be tolerated, the ADA4895 can be used in its place.

For applications where high bandwidth is not as essential but a

wider input voltage range is desired, the LTC6373 can be used.

Alternatively, the ADA4255, which includes overvoltage protection,

can be used for similar applications to replace both the ADA4895

and ADG5421F.

Application-specific variations are possible on the DAC output path

as well. For example, for high voltage operations, the ADHV4702

which can drive outputs up to ±110 V, can be added to the output

signal path.

GETTING STARTED

1. Flash an SD card with the Analog Devices Linux Kuiper image.

2. Configure the SD card with the appropriate boot files.

3. Attach the EVAL-CN0584-EBZ to the EVAL-CN0585-FMCZ

through the AFE connector.

FMC connector.

5. Connect the power supply to the EVAL-CN0585-FMCZ.

6. Connect the Ethernet cable and the UART micro-USB cable to

Zedboard, and the other ends to the host PC.

7. Connect the EVAL-CN0584-EBZ analog I/O ports as shown in

Figure 14 using the SMA cables and terminations.
