First Steps: Quick Measurement with Eval-ADuCM350 & EKSP Labview GUI

The following is a short easy guide to get an Impedance measurement plotted on your PC on receipt of the ADuCM350 evaluation kit, the Eval-ADuCM350EBZ.

The EKSP is GUI based PC software coupled with firmware running on the Eval-ADUCM350EBZ evaluation board which allows the user to easily perform analog front end (AFE) measurements, without having to write any embedded software.

This process assumes you have not downloaded new code on to part or erased the EKSP.hex file that has been downloaded to the ADuCM350 by default. Please go to ADuCM350 FAQ Evaluation Kit Software Platform if you need to re-download EKSP.hex file.

Step 1. Download EKSP Labview GUI Software

The EKSP installer can be downloaded from the ADuCM350 Design Resources Downloads.  This installer will install the GUI based PC software.

Step 2. Connect Eval-ADuCM350EBZ board to PC

Once the software is installed, connect the emulator board (not yet connected to the motherboard) to the target PC using the USB cable provided and open Device Manager (can be found in Control Panel) on the PC. Under Ports, the emulator board will be recognized as JLink CDC UART Port (COMX, where X is the COM port number). Take note of the COM port number.

Please ensure the Switch Mux Config Board is mounted correctly on the Eval-ADuCM350EBZ board as shown below.


Step 2. Run EKSP Labview GUI

Launch the ADuCM350 EKSP GUI software. ADuCM350_EKSP.exe can be found in the Start menu under All Programs -> Analog Devices -> ADuCM350 or in the installation directory (if the default installation path is used: C:\Program Files (x86)\Analog Devices\ADuCM350).

The software will automatically detect the available COM ports and connect with the board. If more than one board is detected, the user will have the option of which board to connect to.

If the software fails to connect, try some or all of the following:

  • Ensure that the USB-SWD/UART-EMUZ emulator board is connected to the PC and to the Eval-ADUCM350EBZ motherboard
  • Reset the Eval-ADUCM350EBZ motherboard
  • Check that the links on the Eval-ADUCM350EBZ motherboard are in the correct (default) positions see UG-668 in Design Documentation folder.

Step 3. Quick Impedance Measurement (Frequency Sweep)

Once GUI Opens:

  1. Click Go
  2. Click Plot

By default, the ADuCM350 EKSP software is configured to do a frequency sweep impedance measurement, just by clicking Go. The default values will trigger multiple impedance measurements, each with an AC excitation voltage amplitude of 6.36 mV and frequencies from 1 kHz to 50 kHz in 1 kHz steps.

While the measurements are being performed, the mouse cursor will change to the system busy cursor and the Impedance Measurement Status LED will light. Once the measurements are complete, the LED will extinguish and Measurement Return Data will be populated with results.

To view a simple plot of the results, click the Plot button below the results and a plot will open in a separate window, as shown in Figure 6. Click Plot on both the ADuCM350 EKSP Tab and again on the Plot AFE Results Tab, to plot the values specified in the Plot Selection drop down menu (Impedance Magnitude vs. Frequency by default). Alternative plotting options can be found in the Plot Selection drop down menu. Click Close to close this window.

The default plot below is a Measured Versus Theoretical Impedance Frequency Sweep.

For more information on the EKSP Labview GUI  and how to used it please refer to

ADuCM350 FAQ Evaluation Kit Software Platform which is an FAQ and has a link to the EKSP Userguide.
