15、 carry out the test suites: the operating frequency range(s) of the equipment; for each of the frequency ranges, the corresponding nominal re-transmission bandwidth(s) of the equipment; the type of the antenna: integral or dedicated; the intended combination(s) of the radio equipment power settings
16、and one or more antenna assemblies and their corresponding e.i.r.p. spectral density levels; the normal and the extreme operating conditions (e.g. voltage and temperature) that apply to the equipment; the type of equipment, for example: stand-alone equipment, plug-in radio device, combined equipment
17、, etc. 5.3.2 Transmit Frequency Band 5.3.2.1 Test conditions These measurements shall be performed under normal test conditions. For a UUT with antenna connector(s) and using dedicated external antenna(s), or for a UUT with integral antenna(s) but with a temporary antenna connector provided, conduct
18、ed measurements shall be used. For a UUT with integral antenna(s) and without a temporary antenna connector, radiated measurements shall be used. 5.3.2.2 Test methods The transmit frequency bands are the GNSS frequency bands, or part of these bands, in which the GNSS repeater can re-transmit receive
19、d signals (see table 1). 5.3.2.2.1 Conducted measurement The UUT shall be connected to the spectrum analyser. The settings of the spectrum analyser shall be adjusted to optimize the instruments frequency accuracy. The white- noise input signal from a signal generator shall be applied to the UUT. In
20、the case of devices with an external antenna, the antenna and device input and output impedance should be investigated. If these impedances are not equal to those of the spectrum analyser and the noise source, the resulting mismatch uncertainty should be added to the total uncertainty of the conduct
21、ed measurement not exceeding the values in table 4. The Max Hold function shall be selected and the centre frequency shall be adjusted to the centre re-transmission frequency of the UUT. The maximum mean value of the power envelope shall be measured and recorded. The frequency span of the spectrum a
22、nalyser shall be reduced and the marker shall be moved in a positive frequency increment until the upper, (relative to the centre frequency), -10 dBr relative to the maximum of re-transmission is reached. This value shall be noted as f1. The marker shall then be moved in a negative frequency increme
23、nt until the lower, (relative to the centre frequency), -10 dBr point is reached. This value shall be noted as f2. The centre of re-transmission is calculated as (f1 + f2)/2. This value shall be recorded. ETSI ETSI EN 302 645 V1.1.1 (2010-03) 155.3.2.2.2 Radiated measurement The test set up as descr
24、ibed in annex B shall be used with a spectrum analyser of sufficient accuracy and sensitivity attached to the test antenna. NOTE: An open air test site is most likely not usable for this test due to the GNSS signal interfering with the retransmitted signal. The test procedure is as described under c
25、lause 5.3.2.2.1. Mismatch uncertainties do not apply. 5.3.3 GNSS Repeater Total gain 5.3.3.1 Test conditions For a UUT with antenna connector(s) and using dedicated external antenna(s), or for a UUT with integral antenna(s) but with a temporary antenna connector provided, conducted measurements shal
26、l be used. For a UUT with integral antenna(s) and without a temporary antenna connector, radiated measurements shall be used. The UUT shall be configured to operate at the highest stated transmitter output power level, i.e. the highest gain step. 5.3.3.2 Test method 5.3.3.2.1 Conducted measurement T
27、hese measurements need only to be performed at normal test conditions. For the purpose of this test, the minimum transmitter on-time from the signal generator shall be 10 seconds. The transmitter shall be connected to the measuring equipment via a suitable attenuator and the Gain Gtotalas defined sh
28、all be measured and recorded. The Gain Gtotalshall be determined using a spectrum analyser of adequate bandwidth. The Gain Gtotalto be measured is the highest gain found in any 1 MHz band. Step 0: Connect the signal generator transmitter output signal to the spectrum analyser and check that the sign
29、al is set at -80 dBm/20 kHz. Step 1: Connect the UUT to the spectrum analyser and use the following settings: Centre Frequency: The centre frequency of the GNSS re-transmission under test. Resolution BW: 20 kHz. Video BW: 20 kHz. Frequency Span: 2 x Nominal re-transmission bandwidth (e.g. 40 MHz for
30、 a 20 MHz re-transmission bandwidth). Detector Mode: Average. Trace Mode: Max Hold. Step 2: Connect signal generator to UUT. When the trace is complete, record the level against frequency. ETSI ETSI EN 302 645 V1.1.1 (2010-03) 16NOTE: The detector mode “Average“ is often referred to as “RMS Average“
31、 but do not use Video Average. Step 3: When the trace is complete, capture the trace using the “Hold“ or “View“ option on the spectrum analyser. Find the maximum value of the trace and place the analyser marker on this maximum. The difference between this and the -80 dBm/20 kHz level is the amplifie
32、r gain. It shall be recorded Gain. This Gain added to the sum of the attached re- broadcast antennas is the Gain Gtotal. In case of conducted measurements on smart antenna systems operating in a mode with multiple transmit chains active simultaneously, the Gtotalof each transmit chain shall be measu
33、red separately to calculate the total Gtotalfor the UUT. Step 4: Gtotalshall be recorded in the test report. The Gtotalgain limit is 45 dB i.4. Installed cable losses of up to 3 dB can be assumed. 5.3.3.2.2 Radiated measurement When performing radiated measurements on a UUT with a directional antenn
34、a, the UUT shall be configured/positioned for maximum e.i.r.p. in the horizontal plane. A test site as described in annex B and using the applicable measurement procedures as described in annex C shall be used. The test procedure is further as described under clause 5.3.3.2.1. For measuring the RF o
35、utput power, it is likely that a radiated measurement would be performed using a spectrum analyser or measurement receiver, rather than a wide band power sensor. If this is the case and if the resolution bandwidth capability of the measurement device is narrower than the occupied bandwidth of the UU
36、T signal measured, then the method of measurement shall be documented in the test report. Radiated measurements shall be conducted inside an anechoic chamber and a substitution antenna method used to assess the input level to the GNSS repeater against which the gain measurement will be assessed. The
37、 Gtotalgain limit is 45 dB i.4. Installed cable losses of up to 3 dB can be assumed. 5.3.4 Maximum output power (saturation e.i.r.p.) 5.3.4.1 Test conditions For a UUT with antenna connector(s) and using dedicated external antenna(s), or for a UUT with integral antenna(s) but with a temporary antenn
38、a connector provided, conducted measurements shall be used. For a UUT with integral antenna(s) and without a temporary antenna connector, radiated measurements shall be used. The UUT shall be configured to operate at the highest stated transmitter output power level, i.e. the highest gain step. 5.3.
39、4.2 Test method 5.3.4.2.1 Conducted measurement These measurements need only to be performed at normal test conditions. For the purpose of this test, the minimum transmitter on-time from the signal generator shall be 10 seconds. The transmitter shall be connected to the measuring equipment via a sui
40、table attenuator and the power as defined shall be measured and recorded. ETSI ETSI EN 302 645 V1.1.1 (2010-03) 17Step 0: Connect the signal generator transmitter output signal to the spectrum analyser and check that the signal is set at -80 dBm/20 kHz. Step 1: Connect the signal generator to the UU
41、T and connect the UUT to the spectrum analyser and use the following settings: Centre Frequency: The centre frequency of the GNSS re-transmission under test. Resolution BW: 20 kHz. Video BW: 20 kHz. Frequency Span: 2 x Nominal re-transmission bandwidth (e.g. 40 MHz for a 20 MHz re-transmission bandw
42、idth). Detector Mode: Average. Trace Mode: Max Hold. Step 2: When the trace is complete, record the level against frequency. NOTE 1: The detector mode “Average“ is often referred to as “RMS Average“ but do not use Video Average. Step 3: When the trace is complete, the trace shall be captured using t
43、he “Hold“ or “View“ option on the spectrum analyser. Find the maximum value of the trace and place the spectrum analyser marker on this maximum and record its level. Step 4: Increase the signal generator output in steps until the recorded value is less than 1 dB greater than the previous value, if t
44、his condition is not met continue and repeat steps 1-3 increasing the signal generator output by 2 dB each time until it is. Record this analyser value as the saturation output power. The test is now complete. Step 5: The saturation output power shall be recorded in the test report. NOTE 2: If the r
45、ecorded value of the saturation e.i.r.p. is less than the recorded output power of the GNSS repeater value identified during the total gain measurement in clause 5.3.3, then clause 5.3.3 is repeated using a signal generator input signal that is lower than that previously used, (-80 dBm/20 kHz). The
46、new signal generator input signal value for the measurement of gain in clause 5.3.3: is 50 dB below the identified saturation output power of clause 5.3.4. 5.3.4.2.2 Radiated measurement When performing radiated measurements on a UUT with a directional antenna, the UUT shall be configured/positioned
47、 for maximum e.i.r.p. in the horizontal plane. A test site as described in annex B and using the applicable measurement procedures as described in annex C shall be used. The test procedure is further as described under clause 5.3.4.2.1. For measuring the RF output power, it is likely that a radiated
48、 measurement would be performed using a spectrum analyser or measurement receiver, rather than a wide band power sensor. If this is the case and if the resolution bandwidth capability of the measurement device is narrower than the occupied bandwidth of the UUT signal measured, then the method of mea
49、surement shall be documented in the test report.
