Start : Start the Custom Test. Stop : To Stop the Test Cycle Pause : To Pause the Test Temporarily Continue : To Continue the Test Cycle Exit : To exit from this option C) ABOUT Gives information about the Application and other Contact Information D) QUIT Quit from the Application 5) TEST SCRIPT AND PARAMETERS • Speed Data transfer speed, supports SIR (9600, 19.2K, 38.4K, 57.6K, 115.2K), MIR (0.576M,1.152M) and FIR (4M). • Frame size of the test frame, 64, 128, 256, 512, 1024, or 2048 bytes. Note 1: Some device does not support big frame for test even it tell you "I do" during the negotiation. That is only for data transfer. For example, windows IrDA stack support 2048-byte for data transfer but only 256-byte and less for test frame. Note 2: At low speed use big frame may fail cause by the Max Turnaround Time. For example at 9600 and MTAT is 500 ms, to transfer a 512-byte frame may take • Number of frames: 1- 255 • Data Patterns of Test Frame 1. All 00: all 0x00. Each SIR byte has nine IR pulses. 2. All FF: all 0xFF. Each SIR byte has only one IR pulse. 3. Random: pseudo random sequence of bytes 4. 00&FF mixed: Repeated sequence of the following 8 bytes: {0x00,0x00,0x00,0x00,0xFF,0xFF,0xFF,0xFF} 5. Double width: (special for FIR test) all 0x33 6. Mixed pulses: (special for FIR test) Repeated sequence of the following 5 bytes: {0x33,0x33,0xBE,0x88,0x88} • Number of cycles: 0 - 10,000. 0 means no limit. The default is 2. Cycle: have sent and received all test frames with the defined parameters, such as speed, frame size, number of frames, data pattern. 6) THE MEANING OF TEST RESULTS AND ERROR CODES Test Result Error Code Remark Pass 0x00 No error. Frame truncated 0x01 XIR, SNRM, RR, and TEST successful. But the Test response(s) received is (are) truncated. This is allowed according to IrLAP Version 1.1, but the propose of sending and receiving TEST commands/responses are not accomplished (due to this loophole in IrLAP Version 1.1) XID frame failed 0x99 after repeated 0-slot XID commands, IR3200M did not receive correctly formatted XID response. SNRM frame failed 0x89 XID successful, SNRM sent, IR3200M did not receive correctly formatted UA response. RR frame failed 0x79 XID and SNRM successful, IR3200M received UA response indication that the intended data rate is supported and set to this data rate. But after IR3200M repeated sending RR commands at that data rate, IR3200M did not receive correctly formatted response. Rate not supported 0x81 XID and SNRM successful, IR3200M received UA response indicating that the intended data rate to be tested is not supported. First test frame failed 0x09 XIR, SNRM, and RR successful, but IR3200M never received any correctly formatted Test frame response. Test frame failed 0x02 IR3200M will disconnect the connection and quit the current test item if it failed to get correct response to anyone of its test frames. This error means that XIR, SNRM, RR, and at least one TEST successful there after. Pass = no any bit error happened with this cycle. Failed = any error happened with this cycle. Error Rate = failed Cycles / Cycles tested 7) PHYSICAL LAYER TEST Check the frame encoding/decoding (Byte stuffing of SIR, Bit-stuffing of MIR or 4 PPM encoding/decoding). Receiver sensitivity test. To socialite frames from the secondary device for measuring its physical layer parameters, such as transmitter intensity, timing parameters. 8) IRLAP TEST Check the basic IrLAP layer implement, such as Discovery (XID), Negotiate (SNRM), Data sending / receiving at different speed (FIR/MIR/SIR), FCS (Frame Check Sequence) implements, speed support and changing and etc. 9) BER TEST FFS (Far Field Source), NFS (Near Field Source) test. A) PRESCRIPTION: • The device under test (DUT) can be either a Primary or a Secondary Station. But during the test, the DUT always plays the Secondary role. • The DUT will use its native IrDA hardware and native IrDA driver stack, which implemented the Test Frame2 in IrLAP as specified in the IrDA Protocol Spec. No special test software is necessary during the test at the DUT side. • The Tester (Test Reference station) is a PC with IrDA hardware of controlled IR emission intensity (e.g. ACTiSYS IR2000B/L) and a special test software (e.g. ACTiSYS ACT-IR9003SW), but not stack testing. Tester always plays Primary role. • The BER test at low speed is most time costly. Practically communication failures happen mostly at higher speed and the speed 9600 is the common speed at NRM for discovery and negotiation. To accelerate the BER test we will reduce the test bit- amount of 9.6k and 38.4k test from 10 MBITS to 1 MBITS. • We check the working range (distance at different angle) of transmission by the Intensity measurement and Sensitivity tests. So the BER test will be done only at angle 0°. This is also for accelerate the IrDA compliant test and will provide us with the some information we need. • NFS (Near Field Source) Test Measure the BER with a strong signal source at ...
