RSS是 Really Simple Syndication的缩写(对rss2.0而言,是这三个词的缩写,对rss1.0而言则是RDF Site Summary的缩写,1.0与2.0走的是两个体系)。
RSS 基于XML,所有的 RSS 必须遵循w3c网站上公布的XML 1.0 规范。
在一个RSS文档中,根元素是<rss>,带有一个必备属性version,用以指明该文档遵循的rss规范,如果rss文档遵循本规范,则version值必须是2.0。
<rss>元素只有一个子元素,包含关于频道的一些信息。频道(channel)是整个blog,项(item)指一篇文章或日志(也有称这为post)。

4.3 TEST GROUPS
The test groups are organized in 3 levels. The first level defines the protocol groups representing the protocol services. The second level, separates the protocol services in functional modules. The last level in each branch contains the standard ISO subgroups BV and BI (not shown in Figure 4.3 on page 12).
4.3.1 Protocol groups
The protocol group identifies the kind of test for Bluetooth RF test purposes: ?Transmitter
?Transceiver
?Receiver
4.3.2 Main test group
The main test groups are the capability group, the valid behavior group and the invalid behavior group.This sub group provides testing of the major EUT capabilities aiming to insure that the claimed capabilities are correctly supported, according to the ICS.This sub group provides testing to verify that the EUT reacts in conformity with the Bluetooth standard, after receipt or exchange of a valid Protocol Data Units (PDUs). Valid PDUs means that the exchange of messages and the content of the exchanged messages are considered as valid.1221 March 2005Test Suite Structure

Tester calculates average power PAV over at least 20% to 80% of
the duration of the burst. (The duration of the burst is the time
between the leading and trailing 3 dB points compared to the
average power).
f)Repeat b) to e) while the analyzer centre frequency is set to:
the mid operating frequency; and the highest operating frequency.
These frequencies are defined in Frequencies for testing, loopback,

The test case should be performed using loopback mode. If so, the test sys-tem must ensure that the testcase is not failed due to not correctly recog-nized return packets or payload failure, i.e: The test system must provide a means to check the correct packet type. In addition it is recommended that the payload content is checked as well if required.
However, if it is required and the test system does not provide a means to distinguish packet types, the TX mode might be used instead if supported by both, test system and IUT.

?Reference
[1] (Sections 3.2.1.4 and 3.2.3)
?Initial Condition
a)EUT is connected to tester via a 50 ohm connector or a temporary 50 ohm connector or if there is no antenna connector via a suitable
coupling device.
b)EUT in test mode loop back or TX mode, with whitening off.
c)Hopping off (transmit and receive frequencies are defined in
扩展:蓝牙rf性能测试规范 / 蓝牙2.1 edr / 蓝牙edr
section 6.3.2).
d)EUT transmits at maximum output power back to the tester.
?Test Procedure
a)EUT transmits the longest supported π/4-DQPSK packet type (2-DH1, 2-DH3, 2-DH5, 2-EV3, or 2-EV5). The user payload bytes
contain PRBS9 pseudo-random data. The number of user payload
bytes is 31 for 2-DH1 packets, 58 for 2-EV3 packets, 356 for 2-
DH3 packets, 358 for 2-EV5 packets or 656 for 2-DH5 packets.
b)EUT transmits at the lowest operating frequency.
c)Tester calculates the initial center frequency error for a packet
transmitted by the EUT using the following method applied to the
basic rate portion of the packet:
i.Tester determines the start time of the first preamble bit p0
using the measurement method.
ii.Tester calculates the frequency deviations at the bit centres
(referenced to p0) of the packet header bits, relative to the ideal
carrier frequency.
iii.Tester selects those bits from the header that have the same
value as both the previous and following bits so are not
significantly affected by inter-symbol interference (there will be

The tester may also select other bits from the header , but the frequency deviations of these bits must be compensated to remove inter-symbol interference.iv.Tester calculates the average frequency deviation ?ω1 of those selected packet header bits that represent a transmitted ‘1’.
v.Tester calculates the average frequency deviation ?ω2 of those selected packet header bits that represent a transmitted ‘0’.
vi.Tester calculates the initial frequency error ωi = (?ω1+?ω2)/2.d)Tester compensates the Enhanced Data Rate portion of the packet for the initial frequency error ωi of the packet.
e)Tester applies a square-root raised cosine measurement filter with a roll-off factor of 0.4 and a 3 dB bandwidth of ±500 kHz to the Enhanced Data Rate portion of the packet.
f)Tester partitions the output of the measurement filter into non-overlapping blocks of 50 μsecs beginning at the nominal start of the synchronization symbol following the reference symbol and finishing at the nominal end of the final payload CRC symbol (the number of user payload bytes has been chosen to make this an integral number of blocks).
g)For each block, tester calculates the sampling phase ε0 and frequency error ω0 for the RMS DEVM for the block, as defined in Annex B of Enhanced Data Rate RF Specification (note that this computation includes information from the symbol immediately before the block in order to generate the 50 differential error vectors). The frequency error ω0 and the RMS DEVM for each block are recorded.
h)For each block, tester calculates the DEVM for each symbol in the block using the sampling phase ε0 and frequency error ω0 for the block as calculated in step g). The DEVM for each symbol is recorded.
i)Repeat steps c) to h) for further packets transmitted by the EUT until a total of 200 blocks have been measured (any remaining blocks from the end of the final packet should be discarded).j)Repeat steps b) to i) while the EUT transmits at:
i.The mid operating frequency; and
ii.The highest operating frequency
k)If 8DPSK modulation is supported by the EUT, repeat steps b) to j) using the longest supported 8DPSK packet type (3-DH1, 3-DH3, 3-DH5, 3-EV3, or 3-EV5). The user payload bytes contain PRBS9 pseudo-random data. The number of user payload bytes is 11 for

?Notes
The tester must check that the correct packet type (for loop back and TX test modes) and payload (for loop back test mode only) have been transmitted by the EUT; any invalid packets should be discarded to avoid corruption of the measurements.
For measurements based on basic rate symbols:
-The requirements on the measurement bandwidth of the tester are the same as used in TRM/CA/07/C Modulation Characteristics.
-The method for measuring the position of bit p0 in the basic rate

For measurements based on Enhanced Data Rate symbols:
-The number of user payload bytes has been chosen to be as close as possible to the maximum packet size, subject to the constraint that the synchronization symbols, the two payload header bytes (for n-
DHx packets), the user payload and the two CRC bytes constitute an integer number of DEVM blocks. This ensures that the modulation accuracy of all symbols, other than the trailer symbols, is measured. -The PRBS9 pseudo random generator is initialized with a seed of all ones at the beginning of each test packet. The first PRBS9 output bit represents the least significant bit of the first user payload byte.
-The definition of the square-root raised cosine measurement filter is given in [RF Spec]. The measurement filter frequency response
must be accurate of ±0.25 dB up to 0.65 MHz from the carrier
frequency and must provide at least 40 dB suppression for
frequencies more than 0.8 MHz from the carrier frequency. The
measurement filter requirement is referenced to the connector on the EUT, so includes the contributions due to all aspects of the signal
processing applied by the tester.
-The tester must give an RMS DEVM of less than 3% and a Peak
DEVM of less than 8% when a test signal from a reference signal
generator is applied and the defined test procedure is followed. This requirement must be met when the test signal has any frequency
error up to ±75 kHz and any symbol rate error up to ±20 ppm.

6.6 BIT ERROR RATE (BER) MEASUREMENTS
BER measurements are carried out by comparing data in the payload fields transmitted by the tester with data in the payload fields received from the EUT. If the tester does not support the loop back method of measuring BER for 2 Mbps or 3 Mbps, it is allowed to use an alternative measurement method as specified in Section 6.2.
Payload as used in this Test Specification will mean the EUT transmitted data. Only Payload data is counted for the BER measurement. The Payload header and Payload CRC are ignored.
If the EUT is unable to loop back a packet (e.g. sync not found or header check fails), this packet shall be disregarded from the BER measurement. The EUT shall regenerate the payload CRC based on the actual received payload bits.Let the number of payload bits counted in error be γ , let the number of payload bits received (via loop back) from the EUT be ξ, then:
For BER sensitivity testing and floor testing an Early Exit option applies. If the early exit option is exercised the required number of bits (ξ) and BER Limit are given in Table6.5 and Table6.6

“The measurement uncertainties of the used measurement equipment must be equal or better as described above. The verdicts of the TCs consider already these measurement uncertainties.”
NOTE: All figures reflect a 95 % confidence level.
Note 1: All values are tentative.
Note 2: 4 dB for frequencies above 4 GHz.
The values include the mismatch between the measurement equipment and the EUT or antenna gain uncertainty of the measurement equipment.
6.11 TEST CASE MAPPING
The test case mapping list shown below determines which test case is applica-ble depending on the supported features. The “support” column has to be filled out according to the supported feature. The feature list with their item numbers is derived from the PICS proforma for Radio (RF) document which includes the IXIT table as well. If a feature is supported according to the logical connection under “item”, the corresponding test case has to be performed.
For purpose and structure of the PICS/proforma and instructions for completing the PICS/PIXIT proforma refer to the Bluetooth PICS-PIXIT Proforma docu-ment.
