Step 3a

Choose Config > Bits > Data Bits to open the Bit Mask

screen. Configure the number and location of the data bits

used to calculate the FFTs.

Make sure that the number of bits matches the resolution of the

converter. All of the supported evaluation boards are MSB

justified, so check the number of bits for the converter starting

with Bit 15 (MSB). Exceptions to this are the AD9280, AD9281,

AD9200, and AD9201. For these four ADCs, check the number

of bits starting with Bit 13.

If a single ADC is being evaluated, check only Channel A and

the appropriate bits under Channel A. If a dual ADC is being

evaluated, check Channel A and Channel B on the Channel

Select screen. (Config > Channel Select).

Step 4

If evaluating a demultiplexed ADC, go to Config > Channel

Select, opening the Channel Select pop-up menu, and check the

Interleaved Data box. This automatically selects both Channel

A and Channel B. When using a dual ADC, select only the

appropriate channel that corresponds to the ADC that is being

evaluated. Channel A is the default selected channel at startup.

Step 4a

Note that Channel A in the software corresponds to Channel 1

on the FIFO schematics and the bottom FIFO (U201) on the
