Recommended IrDA Certification Test Plan

I. BACKGROUND:

IrDA Test Council has established Inter-Op test plan and certification procedure as well authorized Test Lab's to assure the inter-operability among IrDA-enabled products, even across different device classes. Within each device class, there will be one or more product models qualified and certified as "IrDA Reference Product" which can be used by the Test Lab's or manufacturers as Reference to test the inter-operability and "IrReady" qualification of their IrDA products. Some of the key elements are summarized in this User's Manual and the detail can be found either from IrDA web site: http://www.irda.org or more easily, linked directly to its right location from ACTiSYS web site: http://www.actisys.com.

ACTiSYS Corp. operates two of the first five worldwide IrDA Inter-Op Test Lab's authorized by IrDA Test Council in July 1998. ACTiSYS is the first company among this first group of authorized Test Lab's with full certification capability since October 1998; IrDA Compliance (system hardware and protocol software) Test to qualify DUT for "IrDA Reference Product" certification, and IrDA Inter-Op Test to qualify DUT for "IrReady" certification.

You can now use IR3000M to carry out IrDA BER (Bit Error Rate) self test of your IrDA-enabled products following the procedures recommended below. After you have completed this self test, you may fill out the appropriate Test Lab. report forms available from ACTiSYS at irda-info@actisys.com and submit these forms to any of the IrDA Test Lab. This will enable speedy completion of IrDA certification process at lower cost!

II. "IrDA REFERENCE PRODUCT" QUALIFICATION TEST:

     A. TEST PROCEDURE:

      1. BER Test Using IR3000M In "CUSTOM TEST" Mode

  1. Test File Structure:

    "CUSTOM TEST" setting: 4 test patterns x 2 way test x frame size x number of frames.

      b. Test File Size: (Derived from IrDA Standards - Physical Spec.)
    1.25MBytes (BER in 0 x 10-7): For IR speeds of: 9.6K, 19.2K, 38.4K, 57.6K and 115.2Kbps.

    12.5MBytes (BER in 0 x 10-8): For IR speeds of 1.15M and 4Mbps.

      c. Speed, Distance and Angle:
          Speed: All baud rates.
          Distance: 0 cm, 50 cm, 100cm or maximum capable distance of zero BER.
          Angle: 0 and 15 degrees left/right and up/down. (Only air, no reflective surface in between.)

     d. Reference Station IR Emission Power Level: (IR3000M IR Emission = 200mw/SR)
         Min. Distance Test: 200mw/SR at 1 cm = 500mw/SR (IrDA Spec.NFS) at 1.6 cm.
         Max. Distance Test: 200mw/SR at 144cm = 100mw/SR (IrDA Spec.FFS) at 100cm.
 
     e. Alternative Desktop Tester:
         If you prefer desktop PC with lower-cost IrDA tester and more jumper flexibility than IR3000M, you may
         review our Desktop FIR Tester, ACT-IR2000B/L at www.actisys.com

     2. IrDA Physical Compliance Test
 

     a. Required Equipment
         The following list represents the minimal set of test equipment required to perform the tests outlined in this section:
         Please refer to IrDA Inter-Op Test Plan at www.actisys.com
 
     b. Assumptions

The tests in this section will rely heavily on Bit Error Rate (BER) tests. In order to simplify test results, we will presume that BER tests are pass/fail. In other words, when bit errors begin to occur, the device under test will be deemed to be failing. It will be deemed to be passing when no bit errors occur.

Because of the dependency on BER tests, IrDA reference products must support test frames so that consistent test methods can be established and utilized by all IrDA Inter-op Tests Labs for all candidate reference products.

An IrDA Reference Product must support all SIR baud rates from 9600 bps up to its maximum speed. For example, if a device's maximum speed is 57.6 Kbps, it must also support 38.4 Kbps, 19.2 Kbps and 9.6 Kbps. However, it needs not support 115.2 Kbps if such speed is not suitable for the device. BER tests should be run for all supported speeds.

    III.    HOW TO DESIGN A GOOD IRDA-ENABLED SYSTEM PRODUCTS?

      Most of the IrDA hardware components such as the IR transceiver, the encoder/decoder or the integrated IrDA I/O chip are often tested by the component manufacturer to be IrDA compliant. Each IrDA protocol software layer licensed from third party or developed in-house, can also be individually tested to be IrDA compliant. However, when all these IrDA-compliant components are put together, unexpected result may happen.

      Once the engineering phase is done and manufacturing phase starts, there are many possibilities on the manufacturing line too, due to parts property or assembly variations. Also, after the manufacturing phase is done and the products are shipped, there remains field service issue of screening test in the field or at service centers.

      Methods for system testing must be planned and designed into the IrDA implementation, not an afterthought. A good system test methodology is essential to facilitate both engineering, the production and field service.
       

    IV.   WHAT IrDA MISHAPS CAN OCCUR AND HOW TO TEST THEM?
    Most of engineering mishaps usually are in the area between the Physical Layer and IrLAP. Production mishaps usually are confined to Physical Layer only. Consequently, a very simple and effective system test is to access the "Test Frame" feature of IrLAP as defined in the IrDA Protocol Spec., particularly the test frame feature within a connection. ACTiSYS Corp. has made this test frame source codes available which you may get by contacting: irda-info@actisys.com.

    Most major IrDA hardware or software products have implemented this "test frame" well. These include Microsoft-Windows 95/98 IR drivers, HP-5P/6MP LaserJet printers and many others.

    If implemented well in your IrDA protocol stack, a specially programmed tester tool can fully exercise the Physical Layer and IrLAP layer in the device under test (DUT) automatically. This test can range from very thorough for engineering study or QC diagnosis to very speedy for production, quality control or field screening. Both fashions are especially useful for Inter-op "IrDA Reference Product" and "IrReady" certification tests among different IrDA device classes. ACTiSYS provides such test software, ACT-IR9003SW, IR9000SW, IR3000SW and handheld tester, IR3000M.
