Do not place the MCW-D 100 control unit near digitally controlled equipment. 3. Connect the receiving antennae to the antenna inputs A and B (5) using the appropriate adapter. For stand-alone-operation we recommend using the CA 2411 angled rod antenna and the CA 2444 N(HF) Male - SMA Female adapter. 4. Connect the transmitting antenna to the antenna output (12). For stand-alone-operation we recommend using the CA 2411 angled rod antenna and the CA 2444 N(HF) Male - SMA Female adapter. 5. There must be an unobstructed path between the microphone units and the antennae. The range is around 50 m. For optimum range the surface of the table is important, wood or plastic tables are ideal, but metal tables can cause interferences and reduce the range. 6. Connect the XLR (10) or RCA (14) master output to the input of a mixing console/amplifier. 7. Connect the MCW-D 100 control unit to the mains (7). The internal power supply unit of the control unit can adjust automatically between 110 V and 240 V. 8. Switch on the MCW-D 100 with the On/Off-switch (8) on the rear. The Power LED (1) on the front will illuminate green. 9. Depending on the configuration of the MCW-D 100 control unit 5 or more channel-LEDs will illuminate green (standard: 5 channels). 10. When mounting the MCW-D 100 control unit into a 19"-rack housing leave 1 HU for a ventilation panel. Note •If the system should fail to operate, i.e. the microphone unit is switched on but no sound is heard, press the reset button (3). Should the system still fail to operate, please contact your beyerdynamic representative. •If you press the standby button (2) for more than 3 seconds, you switch off all switched-on MCW-D microphone units within the range of the MCW-D 100 control unit.

During rotation we use the antenna lift system to vary the high from 1 to 4 m. So we find maximum radiation output. At this points we do manual remeasurements. After this we do the same measurements in horizontal position of the receiving antenna. This (horizontal and vertical) is made for all the three planes of the test sample. We use the maximum received results. The detector function and selection of bandwidth are according ANSI C63.2-1996 item 8.2.1 and ANSI C63.4-1992 Item 4.2.

All measurement settings are according to FCC 15.35, 15.205, 15.209, 15.247 and the „Measurement guidelines for FHSS systems“, especially regarding the radiated measurements. It was not possible to do RX-only measurements as according to this communication system the tx is transmitting in packets and listens in the Tx gaps. So we do not have a special RX-only mode. The AF output has been covered, because at the moment special headphones can be connected only. If you need this output please contact beyerdynamic. The samples use the same RF part and the same PCB board. The only difference is in the number of pushbuttons( 1 or 3) and with or without loudspeaker.

Processing gain is defined as the difference in signal to noise ratio between the input and output of the demodulator. The theoretical processing gain of the MAX RF module is dBcodelengthGp Theory 7.11)15log(10 10 ==×= Summary results The measured processing according to the measurement method described in FCC15.247(e)(1) is 10dB. 450-MRE-012-Rev1.docpage 4 of 903/19/02 2:36 PM CONFIDENTIAL Adcon RF Technology B.V.

FCC15.247(e) FCC15.247(e) prescribes the following: “The processing gain of a direct sequence system shall be at least 10 dB. The processing gain represents the improvement to the received signal-to-noise ratio, after filtering to the information bandwidth, from the spreading/despreading function. The processing gain may be determined using one of the following methods: (1) As measured at the demodulated output of the receiver: the ratio in dB of the signal- to-noise ratio with the system spreading code turned off to the signal-to-noise ratio with the system spreading code turned on. (2) As measured using the CW jamming margin method: a signal generator is stepped in 50 kHz increments across the passband of the system, recording at each point the generator level required to produce the recommended Bit Error Rate (BER). This level is the jammer level. The output power of the intentional radiator is measured at the same point. The jammer to signal ratio (J/S) is then calculated, discarding the worst 20% of the J/S data points. The lowest remaining J/S ratio is used to calculate the processing gain, as follows: Gp = (S/N)o + Mj + Lsys, where Gp = processing gain of the system, (S/N)o= signal to noise ratio required for the chosen BER, Mj = J/S ratio, and Lsys = system losses. Note that total losses in a system, including intentional radiator and receiver, should be assumed to be no more than 2 dB.” 450-MRE-012-Rev1.docpage 5 of 903/19/02 2:36 PM CONFIDENTIAL Adcon RF Technology B.V.

Measurement Method To measure the processing gain of the MAX RF module, measurement method (1) of FCC15.247(e) has been used. A reference transmitter is connected to the MAX RF module. n symbols are received by the module. The average signal-to-noise ratio after reception is determined from each symbol, both with the despreading function activated and deactivated. The signal to noise ratio determination is based upon digital samples 1 from the output of the demodulator. The (linear) signal to noise ratio in each case (despreading activated or deactivated) is given by the ratio of the mean energy of the samples divided by the variance of these samples: [] 2 2 2 2 2 1 2 1 _ _ _ _ 1 1 data data lin data data n i dataidata n i idata energynoise energysignal SNR energysignal energynoise k n k n σ μ μ σ μσ μ == = = −= = ∑ ∑ = = where k i is i th sample of a set of n samples. In this measurement the value n equals 5000. The calculated signal-to-noise ratio is converted to a logarithmic scale using )log(10 10 lindB SNRSNR×= The difference between the SNR (dB) values with despreading activated and despreading deactivated is defined as the processing gain (dB).

Measurement Setup The MAX RF module, configured in receive mode, has been mounted on the Adcon Development Platform in order to real-time log all demodulator samples. These samples are stored in a RAM block on the Development Platform. After measurement of 5000 symbols, all sampled data is fed to the RS232 port of the Development Platform for external processing (determining the mean and variance of the samples). The reference t…
