 1.0 INTRODUCTION


 This document is a report of tests to determine the ElectroMagnetic Interference (EMI)
 characteristics of the Model # RBMC—10C presented by Lutron Electronies of Coopersburg,
 Pennsylvania.


 The purpose of the testing was to evaluate the EMI characteristics of the test sample with
 respect to Subpart B and C of Part 15 of the FCC Rules for intentional and unintentional
 radiators.


 Test setups and procedures are described in RSI‘s Test Procedures 4963E (see Appendix B)
 and test results are summarized herein on graphs.


 All test procedures used meet the requirements of the American National Standards Institute
 Procedure C63.4:    "Methods of Measurement of Radio—Noise Emissions from Low—Voltage
 Electrical and Electronic Equipment in the Range of IkHz to 40GHz", dated 17 July 1992.

2.0 DESCRIPTION OF THE TEST SAMPLE:


The RBMC—10C is a tabletop mounted dimmer powered by batteries.               The RBMC—10C
contains a super—heterodyne receiver, a transmitter, and an antenna. It is used to control table
lamps as part of an integrated lighting control system.


The receiver down converts a 433.9MHz carrier frequency using a 423.2MHz local oscillator
producing a 10.7MHz IF signal.        The signal is further processed to decode data.       The
transmitter uses a SAW oscillator and power amplifier, which is keyed ON/OFF to produce the
modulated carrier. Each RBMC—10C contains a micro controller running at 4MHz to ensure
that all transmissions stop within 5 seconds of the button release or within 5 seconds on the
beginning of the transmission or a transmission actuated automatically shall cease transmission
within 5 seconds after activation. Modulation is AM specifically ON/OFF Keyed (OOK) or
sometimes called Amplitude Shift Keyed (ASK) data at 15.625kbps. The antenna cannot be
modified or easily replaced by the user.


The RBMC—10C derives power from the Battery Source located in a compartment on unit.

 4.0 TEST RESULTS


 4.1 Conducted Power Line Measurements, Paragraphs §15.107


  No measurements were performed on the Model # RMBC—10C because it is a battery
 operated unit.

 4.2 Radiated Emission Measurements, Paragraphs §15.33, §15.35, §15.109, §15.205,
     §15.209 and §15.231



  See Figure 2 for a test setup photograph and Figure 3 for a photograph of the fundamental
 frequency bandwidth. Radiated emission measurements were recorded for the test sample at a
 distance of 3 meters, unless otherwise stated. The results offield strength measurements are
 illustrated on Figures 6 for unintentional radiators and Figures 7 and 8 for intentional radiators.
 Radiated emissions were measured with the antenna in both the horizontal and vertical
 polarizations. The antenna was raised 1 to 4 meters in height and the equipment under test
 (EUT) was rotated 360° to maximize the emission.


 For unintentional radiators, the emissions from the EUT were scanned from 30MHz to
 2000MHz sinceits localoscillatoris 423.2MHz.



 For intentional radiators the field strength of emissions of the EUT were measured out to the
 tenth harmonic of the carrier frequency. The carrier frequency is 433.9MHz. The bandwidth
 of the emission shall be no wider than .25% of the center frequency. Bandwidth is determined
 at the points 20dB down from the modulated carrier.


  An average factor of 20dB was applied to the level of the fundamental emission when
  compared to the FCC limit.


 ALL LEVELS COMPLY WITH APPLICABLE LIMITS.

 5.0 CONCLUSIONS


 The evaluation of the Model # RBMC—10C, configured as described herein, indicated that the
 unit complies with the requirements set forth in Subpart B and C of Part 15 of the FCC Rules
 for unintentional and intentional radiators.


     1. The EUT meets the radiated emission limits for unintentional radiators set forth in
        §15.109. The closest measurement was 1.2dB under the limit.


    2. The EUT meets the radiated emission limits for intentional radiators set forth in §15.205,
       §15.209 and §15.231. The closest measurement was 1.4dB under the limit.


    4. The EUT meets the bandwidth requirements set forth in §15.231 (c).




 Certification by the Federal Communications Commission (FCC)is required. This report,
 RSI‘s Test Procedure 4963E and FCC Form 731 must be submitted to the FCC for approval.
