Rev 1.34, June 2, 2004 5.2. Equipment Handling 5.2.1. Attaching and Detaching SMA Connectors The impedance characteristics of SMA connectors can degrade rapidly if they are not handled properly. Such degradation will almost certainly affect measured tests results. To ensure the accuracy of test results, follow these guidelines when attaching and detaching SMA connectors: • Align center conductors carefully before mating connectors to prevent degradation.
Rev 1.34, June 2, 2004 5.3.2. Statistics Display on a PC Connected to a Transceiver The procedures in this section assume that a single Linux PC is connected to each transceiver. To decode and display streaming MPEG-2 video, follow the guidelines for PC selection in section 2.2.2. 5.4.
Rev 1.34, June 2, 2004 Test Procedure: 1. Set up equipment as indicated in Figure 5. Follow the guidelines in section 5.2.1 when making or breaking RF connections. 2. Turn on all test equipment and allow it to warm up for the length of time specified by the manufacturer. 3. Verify that the UWB transceiver is powered on. 4. Open a command window on the Linux PC. 5. Use the cd command as necessary on the Linux PC to move to the directory containing the mode application supplied with the Motorola SDK. 6.
Rev 1.34, June 2, 2004 14. Change the spectrum analyzer settings as follows: a. Sweep range: 3000 MHz to 11000 MHz b. Markers: 3100 MHz and 10600 MHz 15. Note the RF power output of the transceiver between the two marked frequencies (3100 MHz and 10600 MHz) and verify that it is below the –41.3 dBm ceiling specified in paragraph (c) of section 15.517 of the FCC CFR 47, Part 15. The transmit spectrum should be below -51.3 dBm above 4.9 GHz. 16. Change the spectrum analyzer settings as follows: a.
Rev 1.34, June 2, 2004 different angles to the DUT to be identified as positioners are rotated and stopped at a peak-emission angle. (2) The tests in the GPS bands require 1 kHz RBW resulting in 400 Hz steps covering 76 MHz (190k points) in one band and 51 MHz (127k points) in the other. The ESIB allows 250k points in a band, which allows each GPS band to be measured with a single sweep, significantly reducing the workload and time required to take document these measurements.
Rev 1.34, June 2, 2004 Expected Results: Contact the Motorola factory if the results of this test are not approximately those indicated in the text above. 5.5. Total Average Transmit Power Test Summary Description: This test determines the total average transmitted RF power across the entire frequency band from a Motorola UWB transceiver. Note that this measurement is NOT conducted in the same fashion as that used for determining FCC UWB spectral mask compliance (see section 5.3.
Rev 1.34, June 2, 2004 9. Note the reading on the power meter. It should be approximately -10 to -8 dBm. Save this value as it will also be used for computing the Peak to Average Transmit Power ratio as described in section 5.6. Expected Results: The power meter reading should be between -10 and – 8dBm. 5.6. Peak Envelope Power Test Summary Description: This test computes the peak envelope power (PEP) of a transceiver.
Rev 1.34, June 2, 2004 5. Use the cd command as necessary on the Linux PC to move to the directory containing the mode application supplied with the Motorola SDK. 6.

Set the oscilloscope electrical plug-in as follows: a. Time base: 1 nsec per division. b.
Rev 1.34, June 2, 2004 In addition, this test has two other purposes. First, it determines the throughput (bits per second of payload) from UWB transmitter to UWB receiver for various FEC and raw channel rate settings in a line of sight (LOS) environment using a range of scaled antenna separation distances as simulated with a manual attenuator. This test also measures the effect on FER of various channel rate and FEC settings. Sample measurements are provided.
