The ADC Capture and Analysis tab consists of various analysis routines and displays. This tab is used to:

• Set the capture mode to finite or continuous

• Set the number of samples (block size) in Finite Capture mode

• Set the display to volts or codes

• Set the filter type to None or Notch

• Set the Notch Freq to 50 or 60 Hz when the filter type is set to Notch

• Set Analysis Type to All Domain or Time Domain only

• Auto save after capture selector

• Acquire the data by clicking the Capture button

• When the user selects the auto save after capture selector under the ADC Capture & Analysis tab, the GUI uses the settings selected under Analysis to Save, Channels to Save, Data to Save, and Save File Settings. A Results saved successfully! notification is given after every capture.

The captured data can be analyzed in time domain and frequency domain; the data can also be displayed in a histogram format. The ADC Capture and Analysis tab is shown in Figure 28.

By selecting the Time Domain plot, the data are displayed in time domain format. The units can be converted from codes to volts using the drop-down window in the top-left corner of the GUI. For the time domain plot, the mean voltage, root mean square (RMS) voltage, and peak-to-peak voltage are displayed in the Test Results section, which is a pop-up window that opens when the Scope Analysis button is clicked. The Scope Analysis: Test Results section pop-up window is shown in Figure 29.

By selecting the FFT plot, the data are displayed in the frequency domain by performing an FFT on the channel selected. Details of the FFT (including SNR, THD, and so on) are shown in the Test Results section located in the left side of the GUI.

Selecting the Histogram plot displays the data in a histogram format for the channel selected. The data are arranged in the total number of histogram bins set within the tab following acquisition. The histogram analysis (shown in the Test Results section of the GUI) is used to view the mean voltage, root mean square (RMS) voltage, and peak-to-peak voltage.

Four plot modes can be selected: Single Plot mode, Double Plot mode, Three Plot mode and Four Plot mode. In Single Plot mode, only one plot (Time, FFT, or Histogram) can be viewed and analyzed for post processing. In Double Plot mode, any two plots (Time, FFT or Histogram) can be viewed and analyzed. In Three Plot mode, any three plots and in Four Plot mode, any four plots (Time, FFT or Histogram) can be viewed and analyzed.

The following algorithms have been used to find the # of samples for FFT calculation: (a) # of samples for FFT calc. which is power of 2 ≤ min ( (Data rate (sps) × N where N is the value in the

Show data for the last N secs column) , No. of samples )

(b) If ( (# of samples for FFT calc. == No. of samples) && (Filter Type == “None”) ) then # of samples for

FFT calc. = No. of samples

FFT calc. = No. of samples / 2. This is to allow for filter settling.

(d) If ( # of samples for FFT calc. < 32 samples ) then an error msg “Insufficient # of samples for FFT

calculation” will be displayed.

Examples:

www.ti.com

1. No. of samples = 3 Data rate (sps) = 500 Show data for the last 5 secs Then # of samples for FFT calc. which is power of 2 = 2048 ≤ min ( (500 × 5) , 8192 )

2. No. of samples = 8192 Data rate (sps) = 500 Show data for the last 8 secs Then # of samples for FFT calc. which is power of 2 = 2048 ≤ min ( (500 x 8) , 8192 )

3. No. of samples = 8192 Data rate (sps) = 500 Show data for the last 20 secs # of samples for FFT which is power of 2 = 8192 ≤ min ( (500 x 20) , 8192 ) Since (# of samples for FFT calc. == No. of samples) and if (Filter Type = None) then # of samples for FFT which is power of 2 = 8192 Since (# of samples for FFT calc. == No. of samples) and if (Filter Type = Notch) then # of samples for FFT which is power of 2 = 8192 / 2

4. No. of samples = 30 Data rate (sps) = 500 Show data for the last 1 secs Then display Error message “Insufficient # of samples for FFT calculation” since # of samples for FFT which is power of 2 = 16 ≤ min ( (500 × 1) , 30 )

5. No. of samples = 32 Data rate (sps) = 500 Show data for the last 2 secs # of samples for FFT which is power of 2 = 32 ≤ min ( (500 × 2) , 32 ) Since (# of samples for FFT calc. == No. of samples) and If (Filter Type = None) then # of samples for FFT calc. which is power of 2 = 32 Since (# of samples for FFT calc. == No. of samples) and If (Filter Type = Notch) then an error msg “Insufficient # of samples for FFT calculation” will be displayed since # of samples for FFT calc. which is power of 2 = (32 / 2) < 32 samples

5.1 Power Supply

AFE4403 can operate from 2.0- to 3.6-V Rx analog supply (RX_ANA_SUP), 2.0- to 3.6-V Rx digital supply (RX_DIG_SUP), 3.0- to 5.25-V Tx Control supply (TX_CTRL_SUP) and LED driver supply (LED_DRV_SUP).

The power for the board is derived from the USB input (J4) through a forward-biased diode (D5) to avoid reverse current flow. The USB data bus is ESD protected using TI’s ESD protection diode array TPD4E004DRYR (U7). The USB VBUS is fed to the integrated Li-ion linear charger and system powerpath management module, BQ24032ARHLR (U12), which generates greater than 4.2-V output (VCC_BAT). This output is fed to TI’s low-input boost converter with integrated power diode and input/output isolation, TPS61093 (U9), for generating a boosted voltage of 8.97 V. This output is fed to low-noise voltage regulator LP3878-ADJ (U8) for generating 5 V for the LED_DRV_SUP and TX_CTRL_SUP. The boost converter output is also fed to the ultralow-noise linear voltage regulator TPS7A4901DGN (U13) for generating 3 V for the RX_ANA_SUP and RX_DIG_SUP. The boost converter output is also fed to the ultralow-noise linear voltage regulator TPS7A4901DGN (U14) for generating 3 V for MSP_DVCC and MSP_AVCC.

Test point and series jumper resistors are provided to make sure the power supplies to the board are correct. The corresponding voltages on AFE4403EVM are given in Table 2.

10.7 Windows 8 Support for Device GUIs

At GUI Start up, sometimes the GUI might show a broken arrow as seen in Figure 52. One of the reasons for this issue may be due to a missing update of .NET FRAMEWORK 3.5 (includes .NET 2.0 and .NET

3.0).

www.ti.com

The .NET FRAMWORK 3.5 is needed for the GUI to:

• Check if Python is Installed

• Checking and setting environment variables needed for the scripting feature in the GUI

Points to Remember:

• There is no download for the .NET Framework 3.5 for Windows 8 or Windows 8.1. The user must

enable the .NET Framework 3.5 in Control Panel by following the instructions provided in this article.

• Use the .NET Framework 3.5 for apps built for versions 2.0 and 3.0 as well as 3.5.

• Installing a Windows language pack before installing the .NET Framework 3.5 will cause the .NET

Framework 3.5 installation to fail. Install the .NET Framework 3.5 before installing any Windows language packs. (Source: http://msdn.microsoft.com/library/hh506443(v=VS.110).aspx)

There are two methods to resolve this.

10.8 COM Port

It has been observed that on certain machines, the GUI will not work for lower COM ports. When the GUI and the USB drivers are installed correctly and the Device Manager shows the AFE44x0SPO2EVM recognized as a virtual COM port, but the GUI cannot establish communication to the AFE44x0SPO2EVM and shows the Device Communication Error, change the COM port to a higher number (greater than 25).

1. User agrees and acknowledges that EVMs are intended to be handled and used for feasibility evaluation only in laboratory and/or development environments. Notwithstanding the foregoing, in certain instances, TI makes certain EVMs available to users that do not handle and use EVMs solely for feasibility evaluation only in laboratory and/or development environments, but may use EVMs in a hobbyist environment. All EVMs made available to hobbyist users are FCC certified, as applicable. Hobbyist users acknowledge, agree, and shall comply with all applicable terms, conditions, warnings, and restrictions in this document and are subject to the disclaimer and indemnity provisions included in this document.

2. Unless otherwise indicated, EVMs are not finished products and not intended for consumer use. EVMs are intended solely for use by technically qualified electronics experts who are familiar with the dangers and application risks associated with handling electrical mechanical components, systems, and subsystems.

3. User agrees that EVMs shall not be used as, or incorporated into, all or any part of a finished product.

4. User agrees and acknowledges that certain EVMs may not be designed or manufactured by TI.

5. User must read the user's guide and all other documentation accompanying EVMs, including without limitation any warning or restriction notices, prior to handling and/or using EVMs. Such notices contain important safety information related to, for example, temperatures and voltages. For additional information on TI's environmental and/or safety programs, please visit www.ti.com/esh or contact TI.

6. User assumes all responsibility, obligation, and any corresponding liability for proper and safe handling and use of EVMs.

7. Should any EVM not meet the specifications indicated in the user’s guide or other documentation accompanying such EVM, the EVM may be returned to TI within 30 days from the date of delivery for a full refund. THE FOREGOING LIMITED WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY TI TO USER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE. TI SHALL NOT BE LIABLE TO USER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES RELATED TO THE HANDLING OR USE OF ANY EVM.

8. No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or combination in which EVMs might be or are used. TI currently deals with a variety of customers, and therefore TI’s arrangement with the user is not exclusive. TI assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or services with respect to the handling or use of EVMs.

9. User assumes sole responsibility to determine whether EVMs may be subject to any applicable federal, state, or local laws and regulatory requirements (including but not limited to U.S. Food and Drug Administration regulations, if applicable) related to its handling and use of EVMs and, if applicable, compliance in all respects with such laws and regulations.

10. User has sole responsibility to ensure the safety of any activities to be conducted by it and its employees, affiliates, contractors or designees, with respect to handling and using EVMs. Further, user is responsible to ensure that any interfaces (electronic and/or mechanical) between EVMs and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard.

11. User shall employ reasonable safeguards to ensure that user’s use of EVMs will not result in any property damage, injury or death, even if EVMs should fail to perform as described or expected.

12. User shall be solely responsible for proper disposal and recycling of EVMs consistent with all applicable federal, state, and local requirements.

Certain Instructions. User shall operate EVMs within TI’s recommended specifications and environmental considerations per the user’s guide, accompanying documentation, and any other applicable requirements. Exceeding the specified ratings (including but not limited to input and output voltage, current, power, and environmental ranges) for EVMs may cause property damage, personal injury or death. If there are questions concerning these ratings, user should contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the applicable EVM user's guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using EVMs’ schematics located in the applicable EVM user's guide. When placing measurement probes near EVMs during normal operation, please be aware that EVMs may become very warm. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use EVMs.

Agreement to Defend, Indemnify and Hold Harmless. User agrees to defend, indemnify, and hold TI, its directors, officers, employees, agents, representatives, affiliates, licensors and their representatives harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of, or in connection with, any handling and/or use of EVMs. User’s indemnity shall apply whether Claims arise under law of tort or contract or any other legal theory, and even if EVMs fail to perform as described or expected.

Safety-Critical or Life-Critical Applications. If user intends to use EVMs in evaluations of safety critical applications (such as life support), and a failure of a TI product considered for purchase by user for use in user’s product would reasonably be expected to cause severe personal injury or death such as devices which are classified as FDA Class III or similar classification, then user must specifically notify TI of such intent and enter into a separate Assurance and Indemnity Agreement.
