| Digital bank-isolated DAQ designs provide protection for digital backend circuitry and reduce ground loop and common mode interference between banks. They feature multiple DAQ signal chains per ground plane, and can be implemented with fewer digital isolation devices than channel-to-channel isolated systems. | Digital bank-isolated DAQ designs provide protection for digital backend circuitry and reduce ground loop and common mode interference between banks.

| === Configuring Channel Gains === | === Configuring Channel Gains === |
| The [[ADI>CN-0393]] hardware allows for software-controlled channel gain setting for the two data acquisition channels (channels A and B). It does this by setting the gain address pins on each channel’s [[ADI>AD8251]]s. These gains are configured via the **CA Gain** and **CB Gain** controls in the **Configuration Tab**. **CA Gain** and **CB Gain** set the gains for channels A and B, respectively. When a new gain is selected for either control, the hardware updates the respective channel’s [[ADI>AD8251]] gain setting. When the update is complete, the **Status** bar will display the current gain settings and input ranges for both channels. The **CA Input Range** and **CB Input Range** indicators also show the corresponding input ranges for the current channel gain settings. | The [[ADI>CN0393]] hardware allows for software-controlled channel gain setting for the two data acquisition channels (channels A and B).

| Capturing results/samples can be performed by pressing either the **Single Capture** or **Continuous Capture** controls on the software’s front panel. The **Single Capture** button performs a single set of conversions, and **Continuous Capture** performs repeated sets of conversions. The number of samples in the set of conversions in determined by the **Num Samples** control. For example, if **Num Samples** is set to 8192, then 8192 conversions will be performed, resulting in 8192 results for each channel. Results can be viewed on the **Waveform**, **Histogram**, **FFT**, and **Summary** tabs after the conversions are executed (see **Viewing Results**). | Capturing results/samples can be performed by pressing either the **Single Capture** or **Continuous Capture** controls on the software’s front panel.
