Question 12

ADIS16228/PCB-ADISUSB Tutorial

Accepted Answer

Q: 
 How can I use the ADIS16228 evaluation tools to determine if this product meets my performance needs? 
 ----------------------------------------------------------------------------------------------------------------------------------- 
 A: 
 This post illustrates an experimental approach of observing the vibration signature associated with a example system, using the ADIS16228 and its evaluation tools. In this example, we decided to find out if we can use the ADIS16228 to determine the operational state of a compressor, which produces cold air in a temperature control chamber. For this compressor, there are three different states, which appear to have different vibration profiles: OFF, IDLE and ON. The combination of the ADIS16228/PCBZ , ADISUSB , a laptop and the ADIS16228 evaluation software provided a convenient platform for analyzing the vibration on the compressor's enclosure. Since we didn't want to drill holes in the enclosure (at least to start with), we attached the ADIS16228/PCBZ to the top side of the enclosure (in the middle), using double-sided tape. In order to minimize the mass of the sensor, we used a 6" ribbon cable to connect the ADIS16228/PCBZ (J1) to the ADISUSB (J1), as shown below. For complete setup guidelines, please see the ADIS16228-ADISUSB User Guide Wiki . 
 
 Once we secured the ADIS16228/PCBZ on the surface of the enclosure, we plugged the ADISUSB in to the PC-USB port and opened the ADIS16228 Evaluation Software package. Under Main Control, we established (or verified) the following settings: 
 
 Click on Interface , then on USB , to make sure that the board was connected. 
 Under Main Control , select Manual for the Rec Mode 
 Under Main Control , select Hanning for the Window 
 Under Main Control , select None for Storage Options . 
 Check the box for Auto Plot 
 Under Sample Rate , make sure that the check box next to SR0 is selected and that the check boxes next to SR1 , SR2 , and SR3 are not selected. 
 Keep FFT AVGs equal to 1 and the Range equal to 0 to 20g . 
 Click on Null and wait ~1 second for it to complete 
 Click on Start , which will trigger data collection, processing and a plot. 
 
 The following plot showed us that there appears to be vibration, but at levels that are much lower than the 20g range . 
 
 After reviewing this plot, we clicked on the Scale(g) button to scroll down to a range, which better represented the FFT data. 
 
 After observing that the peak vibration energy was at lower frequencies, we changed to the the Sample Rate setting of SR1 and selected a Range of 0 to 5g for this Sample Rate . From the following plot, we can observe the impact of finer frequency resolution. 
 
 We also experimented with using a Sample Rate setting of SR2 , a Range of 0 to 5g and 8 FFT Averages , in order to reduce some of the variation in the vibration signature. Again, after all settings were complete, we hit Start to trigger the capture/FFT analysis process. In the plot, we observed a large peak at bin 193, which was ~0.1288g (see marker). 
 
 Using the same settings, we put the compressor into IDLE mode and ran another FFT (observed a large change in the peak energy. As we can see, the energy at bin 193 was greatly reduced. From this information, we have a clear difference in FFT signature, between the ON and IDLE states. 
 
 In order to find a signature difference between the IDLE and OFF modes, we used the Scale(g) button to scroll down to a lower range option. In doing this, we found "peaking" at bin 80, which was ~0.0277g. 
 
 When the compressor was in an OFF state, we hit Start again and found that the energy at bin 80 reduced by a large amount. 
 
 From this simple experiment, we can conclude the following: 
 
 While we expect that most applications will require a more thorough investigation of potential behaviors and performacne threats, the ADIS16228 's noise, bandwidth and range appear to be sufficient for the stated goal of discerning a vibration difference betwween OFF, IDLE and ON states. 
 
 In concluding this post, we also want to note that using double-sided tape was helpful for this quick demo, but would expect that a complete investigation would want to consider a more rigid attachment approach. The next step in this process will be to determine the appropriate spectral alarm settings for detecting these conditions. More on that in our next post!

Question 13

ADIS16228 Demonstration, Compressor Case

Accepted Answer

Q: 
 Do you have any examples for using the ADIS16228 Evaluation Software and Tools? 
 -------------------------------------------------------------------------------------------------------------------------- 
 A: 
 Yes, here is a simple example, which involved measuring the vibration on the case of a compressor. In this example, we taped the ADIS16228/PCBZ to the top of the compressor, used a ribbon cable (6 inches) to connect it to J1 on the ADISUSBZ. The video provides a quick overview of the application and the three pictures represent the FFT output from the ADIS16228, when the compressor was off, when it was idling and when it was fully operational. From these pictures, one can easily see the difference in vibration on the compressor's case.

Question 14

ADIS16228/PCBZ Breakout Board Cables

Accepted Answer

Q: 
 I see that the ADIS16228/PCBZ has a 16-pin interface connector. Do you sell cables that will help me connect this to my embedded processor systems? 
 ----------------------------------------------------------------------------------------------------------------------------------------- 
 A: 
 On the ADIS16228/PCBZ , J1 is a dual-row, 16-pin, 2mm connector interface that is compatible with standard, 1mm ribbon cable systems. Analog Devices does not sell ribbon cable connectors or assemblies, but there are other companies that provide full cable assemblies or the raw materials required for assembly. For example, check out www.samtec.com/TSCD and click on "Build A Part Number." Here is an example, that is based on Samtec's web site (November 1, 2012). The boxes reflect input options. Since the connector ends are "dual-row," setting the POSITIONS equal to 8 actually reflects 16 pins on each socket connector. For systems that plan to hand-solder to points on their embedded processor board, changing the END ASSEMBLY to "S:Single End" might be worth consideration. In this example, we selected a LENGTH of 6 inches. For SPI communications, signal integrity is important. Without the use of drivers, damping resistors and filter capacitors, we have found that we can achieve reliable communication over 12 inches of this type of cable. Longer lengths will probably work, but may require additional attention to assure appropriate timing and signal integrity. 
 
 After you click on Use The Part, the web site will tell you the suggested part number and will also tell you if this is a standard part number. 
 
 For direct connection to the EVAL-ADIS evaluation system , we would suggest using a length of 2 inches, which would generate the following part number:TCSD-08-D-02.00-01. 
 We sincerely hope that this information helps you. This post is intended to reflect the style of conversation that we might have, while working in the lab, but it not intended to recognize Samtec as an "official" or "preferred" cable supplier for ADIS16xxx customers. While Samtec has provided the ADIS16228 team with excellent service, we cannot be responsible for managing this relationship for our customers. We encourage your to find a quality connector/cable supplier that meets all of your needs. If you have any issues with Samtec's web site, service or products, please contact their customer service team or your local sales representative. 
 Finally, does anybody else have suggestions for this question? We would encourage you to share your experiences through comments.

Question 19

Vibration Analysis with the ADIS16228

Accepted Answer

Q: 
 How can I test the ADIS16228 evaluation tools? 
 A: 
 --------------------------------------------------------------------- 
 The ADIS16228 http://www.analog.com/ADIS16228 is an advanced vibration sensor, that includes a tri-axial accelerometer, data capture, FFT analysis and spectral alarms. In order to test this product on a PC-based platform, use the ADIS16228/PCBZ with the ADISUSBZ evaluation system. The ADISUSB User Guide (UG-363) provides all of the details that are necessary for installing the ADIS16228/PCBZ on the ADISUSBZ system, but here are some tips to remember: 
 
 Make sure that JP1 is set to +3.3V 
 When connecting J1 on both boards, make sure that you align pin 1 
 For the ADIS16228/PCBZ , J1 has 16 pins, while the ADISUSB comes with a 12-pin ribbon connector. Per UG-363 , either cut pins 13-16 from J1 on the ADIS16228/PCBZ or make a 16-pin, 1mm ribbon cable for this purpose. 
 
 Once the physical setup in complete, download the ADIS16228 evaluation software package from www.analog.com/ADISUSB (under Software and Tools) and follow the installation instructions in UG-363 . After installing the software, plug the ADISUSBZ into the PC-USB port and follow the instructions in UG-363 for installing the USB drivers. Once that the driver installation is complete, start the software package and make all of the following changes to the main screen. See the red circles in the figure below, to identify all of the necessary settings.

Here is an example of how to create "vibration" for a demo like this.

Question 20

How do we communicate with the ADIS16228?

Accepted Answer

Q 
 How do we communicate with the ADIS16228? 
 
 A 
 The ADIS16228&rsquo;s addressable user registers manages access to all data and configuration parameters, through a serial peripheral interface (SPI), which many embedded processor platforms support with dedicate ports and a few lines of code. Note that the ADIS16228 operates as a SPI slave and only supports SPI mode 3. This information can impact the embedded interface selection process for customers.
