Test equipment
Test system 5.1.1.1
Measurement See Section 5.2.9, but demodulation AM
Residual AM with a measuring bandwidth of
30 Hz to 23 kHz..................................................................
≤
0.02 %
5.2.11 Output Level
Test equipment -Power meter (Section 5.1, item 8)
- Precision attenuator (Section 5.1, item 9)
- Spectrum analyzer (Section 5.1, item 2)
- Low-noise preamplifier (Section 5.1, item 10)
Test Methods for Level in the Measuring Range of the Power Meter
Test setup Connect power meter to the RF output socket.
Measurement À Setting at the SME
- RF level to be measured (see below), unmodulated.
À Measure the level at output frequencies of 5 kHz to 1500 MHz
(2200/3000/6000 MHz with SME03E/03/06).
Deviation of the output level from the rated value
at frequency
≤
3 GHz.......................................................max.
≤
1 dB
at frequency > 3 GHz ......................................................max.
≤
2 dB
Frequency response at 0 dBm (difference between the lowest and
the highest level)..............................................................max.
≤
1 dB
Recommended test level 13, 10, 8, 7.9, 5, 0, -5, -10, -20, -30 dBm
Test Methods for Low Levels
Test principle Levels below the measuring range of the power meter can be carried
out by means of a comparison measurement using a precision
attenuator and a sensitive test receiver or spectrum analyzer.
Test setup Connect a precision attenuator to the RF output of the SME and a
spectrum analyzer with screened RF measurement cables to its
output.
