Evaluating Performance with the ADCPro Software

The evaluation software is based on ADCPro, a program that operates using a variety of plug-ins. (The

ADS7953EVM plug-in is installed as described in the previous section.)

To use ADCPro, load an EVM plug-in and a test plug-in. To load an EVM plug-in, select it from the EVM

menu. To load a test plug-in, select it from the Test menu. To unload a plug-in, select the Unload option

from the corresponding menu.

Only one of each kind of plug-in can be loaded at a time. If selecting a different plugin, the previous plugin

is unloaded.

Using the ADS7953EVM-PDK Plug-in

The ADS7953EVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS7953. It

consists of a tabbed interface (see Figure 19), with different functions available on different tabs. These

controls are described in this section.

The user can adjust the ADS7953EVM settings when not acquiring data. During acquisition, all controls

are disabled and settings may not be changed.

When a setting is changed on the ADS7953EVM plug-in, the setting immediately updates on the board.

Settings on the ADS7953EVM correspond to settings described in the ADS7953 product data sheet; see

the ADS7953 data sheet for details.

Because the effective sampling rate of the ADS7953 depends upon settings of the Clock Freq and the

number of channels being sampled, the Sampling Rate indicator in the upper right corner of the plug-in

interface is always visible and updates whenever a setting changes that affects the effective 'per-channel'

sampling rate.
