AD7194 Plugin Install

After the AD7194 Plugin is downloaded follow the steps to install the file: - Double click on the AD7194 Plugin. - Connect up your EVAL-AD7194ASDZ to your pc through a controller board. Alternatively, the AD7194 Plugin can be installed through the steps bellow:

  1. From the Start menu of the PC, select All Programs > Analog Devices > ACE> ACE.exe to open the ACE software main window shown below.
  2. Click on the Plug-in Manager Tab in the top left panel in Ace.
  3. Click on the Settings… button.
  4. Hit the + button next to the Zipped Plug-in Sources.
  5. Under the Name write “AD7194”
  6. Under Source hit the … button and set the path to where you have stored the AD7194 Plugin.
  7. Press “Ok”.
  8. Press “Close”.

ACE software Operation

Launching the software

After the EVAL-AD7194ASDZ and controller board are properly connected to the PC, launch the ACE software by taking the following steps:

  1. From the Start menu of the PC, select All Programs > Analog Devices > ACE> ACE.exe to open the ACE software main window shown below
  2. If the EVAL-AD7194ASDZ is not connected to the USB port via the controller board when the software launches, the AD7194 Eval Board icon does not appear in the Attached Hardware section in ACE (see Figure below).To make the AD7194Eval Board icon appear, connect the EVAL-AD7190ASDZ and the controller board to the USB port of the PC, wait a few seconds, and then follow the instructions in the dialog box that opens.
  3. Double click the AD7194 Eval Board icon to open the AD7194 Eval Board view window shown below:
  4. Double click the AD7194 chip icon in the AD7194 Eval Board view window to open the AD7194 chip view window shown below:
  5. Click Software Defaults and then click Apply Changes to apply the default settings to the AD7194

Chip view window

After completing the steps in the Software Installation Procedures section and the Evaluation Board Set-up Procedures section, set up the system for data capture by taking the following steps:

  1. Block icons that are dark blue are programmable blocks. Click a dark blue block icon to open a configurable pop-up window to customize the data capture.
  2. The “Proceed to Memory Map” button brings the user to the memory map of the AD7194. This allows the user to configure the AD7194.
  3. The “Proceed to Analysis” button brings the user to the Analysis tab. This allows the user to see the performance results of the AD7194 and displays the data.

Waveform Window

The Waveform tab graphs the conversions gathered and processes the data, calculating the peak-to-peak noise, rms noise, and resolution.

1) Waveform graph and controls

The data waveform graph shows each successive sample of the ADC output. Zoom in on the data in the graph using the scroll wheel on your mouse or by selecting the magnifying glass.

2) Analysis Channel

The Result section shows the analysis of the channel selected

3) Samples

The Samples numeric control set the number of samples gathered per batch. This control is unrelated to the ADC mode. You can capture a defined sample set or continuously gather batches of samples. In both cases, the number of samples set in the Samples numeric input dictates the number of samples. The Noise Analysis section displays the results of the noise analysis for the selected analysis channel, including both noise and resolution measurements.

4) Capture

Click the Run Once button to start gathering ADC results. Click the Run Continuously button to start gathering ADC results continuously. Results appear in the waveform graph (Label 1).

5) Display Units and Axis Controls

Click the Codes drop-down menu to select whether the data graph displays in units of voltages or codes. This control affects both the waveform graph and the histogram graph. The axis controls is fixed. When selecting Fixed, the axis ranges can be programmed; however, these ranges do not automatically adjust after each batch of samples.

Memory map Window

Use the Memory Map tab to access the registers of the AD7194, shown in the figure below. This tab changes register settings and shows additional information about each bit in each individual register.

1) Export Buttons

The Export buttons on the Register Map tab allow the user to save and load register settings. Click Save to save all the current register settings to a file for later use. Click Load to load a previously saved register map.

2) Register

The Register section shows the value that is set in the selected register. Check the value of the register in this window by clicking on the bits. Clicking any individual bit changes the bit from 1 to 0 or 0 to 1, depending on the initial state of the bit. The register value can also be changed by writing the hexadecimal value in the input field to the right of the individual bits.

3) Bitfields

The Bitfields section shows the individual bitfield of the selected register. The register is broken by name into its bitfields, name of the bitfields, a description of each bitfield, and access information. Show each individual bitfield by pressing the show bitfield button (label 3). Apply these changes using label 4. Search for specific registers using label 5.

4) Register and Bitfield Description and dropdowns

For more information of the register and the bitfields in the register, double click on the register shown by label 2. This will show up the register description shown by label 6.
