3. SYSTEM TEST CONFIGURATION
3.1 Justification

The system was configured for testing in a typical fashion (as a customer would normally use it).
And its antenna was permanently attached to the EUT with fixed maximum length, 3 inches.

When an audio signal is input, the transmitter’s power is turned on automatically, and the
indicator lights in green. Also, when no audio signal is input for about a minute, the
indicator goes out automatically and the power turns off. (Automatic Power On/Off function)

Testing was performed as EUT was operated at frequency 906~908MHz continuously. The worst
case of EUT operating frequency as 106.7MHz is recorded for final data on Pg. 19.

5. CONDUCTED EMISSION DATA

5.1 Test Methods and Conditions

The EUT was under normal operational mode during the conducted emission test. EMI Receiver
was scanned from 450KHz to 30MHz with maximum hold mode for maximum emission.
Recorded data was sent to the plotter to generate output in linear format. At the input of the
spectrum analyzer, a HP transient limiter is inserted for protective purpose. This limiter has a 10
dB attenuation in the range of 450KHZ to 30MHZ. That factor was automatically compensated by
the receiver, so the readings are the corrected readings. The reference of the plot is the CISPR 22
Class B limit in Figure 5.1 through Figure 5.2.

Emissions that have peak values close to the specification limit (if any) are also measured in the
quasi-peak mode to determine compliance.

6. RADIATED EMISSION DATA

6.1 Field Strength Calculation
The corrected field strength is automatically calculated by EMI Receiver using following:
                               FS = RA +AF + CF + AG

where FS: Corrected Field Strength in dBµV/m
      RA: Amplitude of EMI Receiver before correction in dBµV
      AF: Antenna Factor in dB/m
      CF: Cable Attenuation Factor in dB
      AG: Built-in Preamplifier Gain in dB (Stored in receiver as part of the calibration data)


6.2 Test Methods and Conditions

The initial step in collecting radiated data is a EMI Receiver scan of the measurement range below
30MHz using peak detector and 9KHz IF bandwidth / 30KHz video bandwidth. For the range
30MHz - 5GHz, IF bandwidth / 30KHz video bandwidth are used. Both bandwidths are 1MHz for
above 1GHz measurement.

6.3 Test Data

The following data lists the significant emission frequencies, polarity and position, peak reading of
the EMI Receiver, the FCC limit, and the difference between the peak reading and the limit.
Explanation of the correction and calculation are given in section 5.1.

Testing was performed as EUT was operated at frequency 906~908MHz continuously. The worst
case of EUT operating frequency as 106.7MHz (CH2) is recorded for final data.

(1) The limit for emissions within the 902-928MHz band is 50,000uV/m(94dB). Sec. 15.249. The
limit for field harmonics is 500uV/m(54dB). The limit for other emissions is defined in Sec.
15.249.

(2) Because each peak reading is less than the FCC average limit, it is not necessary to show the
calculated average reading based on the pulse train characteristics.
