The EVAL-ADMX3652Z is a 6 ½ digit ±20V dual channel digital voltage meter. Selection within the 3 measurement ranges can be done manually, or through the auto range function. With EVAL-ADMX3652’s small form factor, it can be easily integrated into a system, or can also serve as a benchtop voltmeter when connected with the EVAL-ADMX3652Z-INT, an interface board that enables the EVAL-ADMX3652Z be used with an intuitive GUI for evaluation. This interface communicates from the EVAL-ADMX3652Z via USB to UART with a Windows PC and has 2 voltage measurement channels using banana jack connectors.

The EVAL-ADMX3652Z Evaluation board directly ties its 5V input to the power rail of the EVAL-ADMX3652Z-INT interface board, which eliminates the need for external power supply in the system. To setup for evaluation, use the following sequence::
Figure 3. ADMX3652Z Hardware Setup
Figure 3 illustrates the evaluation system components. To use the system properly, make sure to firmly mount the EVAL-ADMX3652Z to the EVAL-ADMX3652Z-INT board. Next, connect the interface board to the host PC through a USB A to USB B cable. Connect the voltmeter test leads to the banana jack connectors on the interface board, and apply an input stimulus to one or both the interface board measurement channels. Both channels 1 and 2 have a dedicated measurement display on the Software GUI, and contains functions the user can adjust depending on the measurement needs.
From the EVAL-ADMX3652Z webpage the Software pack is available for download. Inside the downloadable zip file should contain 2 installers, the CDM212364 driver and the ADMX3652Z installer. Figure 4 shows the required files for the GUI to be extracted and installed.
Figure 4. ADMX3652Z GUI Driver and Installer
After downloading the files, double-click on the CDM212364 Driver. Run the installer and it will prompt you to extract the driver package, then launch the installer. See Figure 5 for reference.

Next, the License Agreement would appear. Tick “I accept this agreement” then click “Next”. The driver package will then be extracted and installed to your host PC. After it completes the process, click “Finish”. See Figure 6 for reference.
Figure 6. Accept License Agreement then click Finish
This completes the installation of the driver, which will enable the EVAL-ADMX3652Z setup to be automatically detected whenever connected to the host PC.
After downloading the Software pack from the ADMX3652Z webpage, double-click on the ADMX3652Z installer. Run the installer and tick the “I accept the agreement” then click Next. Refer to figure 7.
Figure 7. Run the Installer then Accept License Agreement
Next, select a location where the ADMX3652Z GUI would be installed, then click Finish. Refer to Figure 8.
Figure 8. Select Installation location then click Finish
The software installation is now complete and the ADMX3652 Evaluation GUI is now ready for use.
Figure 9 shows the default setup of the ADMX3652Z GUI after installation and startup.

To start using the GUI, click “Connect”. It will prompt the port selection dialog and will automatically detect the serial port that ADMX3652Z will be using. Click “Confirm”. Refer to Figure 10.

The different functions found within the GUI are the following:
The Connect button changes to Disconnect button when the user has properly established connection with the device. Use this button to disconnect the communication of the GUI with the device. Once disconnected, settings will be disabled and cannot be changed.
If connected, use reset button to change the settings to default and send a signal to the board to reset the EVAL-ADMX3652Z to its default factory settings. Once reset, loading screen willappear (same as the first run) and settings will be disabled.
The status bar displays the status of the GUI, whether it is connected or disconnected. During measurement, it shows the measurement done in one or both the channels.
The measurements displayed in the status bar are also logged into a logs.txt file and can be found on the location where the ADMX3652Z software is installed.
The following measurement configurations are separately available for both channels 1 and 2 of the EVAL-ADMX3652Z. These settings can be configured differently and independently based on user's measurement needs.
Aperture time is the period of time used for reading the input signal. Larger aperture times means better resolution. Select short aperture times for faster measurement speed. The unit used for specifying aperture time with the EVAL-ADMX3652Z is in number of power line cycles (NPLC).
Aperture time can be set and selected either 0.05, 0.1, 0.25, 0.5, 1, 10, or 100.
