Signal Source

A signal generator with 2 outputs is used to generate the differential signals driving the ADRV9002 inputs.

• Set up the first channel to generate the desired signal
• Set up the second channel for tracking the first channel
• Set up the Second channel for signal inversion.

Run the demonstration locally

Power up the unit using this hardware configuration. Wait approximately 60 seconds for the unit to be fully functional.

IIO Oscilloscope will be automatically launched on the system desktop. No configuration is required.

Enable voltage0 ADC channel

Select a Plot Channel to be displayed in IIO Oscilloscope. Click on the check box in the Plot Channel window adjacent to voltage0

Capture Time Domain Signals

Press the Capture / Stop button to begin the capture process.

Capture Frequency Domain Signals with Frequency Markers enabled

Change the capture mode to Frequency Domain. Select an FFT Size and Average. Press the Capture / Stop button to begin the capture process.

Right click in the IIO Oscilloscope plot area. Select a marker option. Press the Capture / Stop button to begin the capture process with markers.

Note the information in the Marker window. This capture shows a signal source of 100 khz with harmonic components.

Shutting down the demo

• Power down the target. Launch a Root Terminal. Type the following

    $ poweroff  
  

• Wait 30 seconds and then you can safely power down the DataStorm DAQ

Run the demonstration via ethernet

Define the host PC IP address

A wired ethernet point to point connection between the host PC and the embedded target is required. Use this link for instructions on how to assign a static IP address to the host Ethernet adapter. Set the following values

• IP address : 192.168.0.1

• Subnet mask : 255.255.255.0

• No entries required for the other fields

Connect to the target terminal

• A wired Micro USB serial port connection between the host PC and the embedded target is required
• Launch a linux terminal (like Tera Term VT or Putty) and connect using serial port
• Select 115200 baud
• Select the appropriate target COM port

Define the target IP address

Type the following at the terminal prompt to set the target IP address

• $ ifconfig eth0 192.168.0.2 up

Launch IIO Oscilloscope

Note: IIO Oscilloscope creates a .osc_profile.ini file in the Users/UserName/Appdata/Local directory. The next time IIO Oscilloscope is opened, the existence of this file delays connection to the target. It is recommended to delete the .osc_profile.ini (if it exists) prior to launching IIO Oscilloscope.

Connect to the target

• Select the Remote Devices option and enter the IP address 192.168.0.2 and click the Refresh button..
• A successful connection results in discovery of the IIO devices. Press OK to continue.

Enable voltage0 ADC channel

Select a Plot Channel to be displayed in IIO Oscilloscope. Click on the check box in the Plot Channel window adjacent to voltage0

Capture Time Domain Signals

Press the Capture / Stop button to begin the capture process.

Capture Frequency Domain Signals

Change the capture mode to Frequency Domain. Select an FFT Size and Average. Press the Capture / Stop button to begin the capture process.

Enable Frequency Markers

Right click in the IIO Oscilloscope plot area. Select a marker option. Press the Capture / Stop button to begin the capture process with markers.

Note the information in the Marker window.

Shutting down the demo

• Power down the target. Type the following at the terminal prompt

    $ poweroff  
  

• Wait until the linux terminal shows

    $ reboot : System Halted
  

• Close out IIO Oscilloscope and all associated windows
