Thank you, Roland -----Original Message----- From: Roland Gubisch ES-Box Sent: Thursday, April 27, 2006 2:21 PM To: John Lair ([email protected]) Cc: Terre Wolak ES-Atl Subject: TCB Certification Review, FCC: TDAFMC200 John, Review of this application is underway and no major issues are foreseen. However to expedite the Grant, I would like to raise one point prior to completion of the review. The Request for Confidentiality asks that internal photos be kept confidential, among other items. The FCC asks for additional justification in the case of internal photos, on the grounds that usually anyone can purchase the product and open it to obtain this information. The FCC accepts the following as suitable justifications for keeping the internal photos confidential: 1) The device is sealed (no screws or other removable fasteners) and would be damaged or destroyed by the attempt to open it; and/or 2) The device is potted, and any attempt to examine the interior would damage or destroy it; or 3) The device is professionally installed, and access is limited to authorized personnel only. Please re-submit the Request for Confidentiality, citing in addition to its existing text the added applicable statements (1) and/or (2) above; or, delete "Internal photos" from the list of exhibits to be held confidential.

Report Number 3091276BOX.001 Page 4 of 18 2.0 Test Summary TEST STANDARD RESULTS FCC Part 15 Subpart C 15.225 SUB-TEST TEST PARAMETER COMMENT FCC Parts 15.205, 15.209, 15.215, 15.225 RF Output Power and Radiated and Restricted Band Emissions Emissions below specified limits Pass FCC Part 15.207 Line-Conducted Emissions Emissions below specified limits Pass FCC Parts 15.225 Frequency Stability Frequency drift must not exceed ±0.01% Pass Report Number 3091276BOX.001 Page 5 of 18 3.0 Sample Calculations The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain (if any) from the measured reading. The basic equation with a sample calculation is as follows: FS = RA + AF + CF - AG Where FS = Field Strength in dBμV/m RA = Receiver Amplitude (including preamplifier) in dBμV CF = Cable Attenuation Factor in dB AF = Antenna Factor in dB AG = Amplifier Gain in dB In the following table(s), the reading shown on the data table reflects the preamplifier gain. An example for the calculations in the following table is as follows. Assume a receiver reading of 52.0 dBμV is obtained. The antenna factor of 7.4 dB and cable factor of 1.6 dB is added. The amplifier gain of 29 dB is subtracted, giving a field strength of 32 dBμV/m. This value in dBμV/m was converted to its corresponding level in μV/m. RA = 52.0 dBμV AF = 7.4 dB/m CF = 1.6 dB AG = 29.0 dB FS = 32 dBμV/m Level in μV/m = [10( 32 dBμV/m)/20] = 39.8 μV/m The following is how net line-conducted readings were determined: NF = RF + LF + CF + AF Where NF = Net Reading in dBμV RF = Reading from receiver in dBμV LF = LISN Correction Factor in dB CF = Cable Correction Factor in dB AF = Attenuator Loss Factor in dB To convert from dBμV to μV or mV the following was used: UF = 10 (NF / 20) where UF = Net Reading in μV Example: NF = RF + LF + CF + AF = 28.5 + 0.2 + 0.4 + 20.0 = 49.1 dBμV UF = 10 (48.1 dBμV / 20) = 254 μV/m Report Number 3091276BOX.001 Page 6 of 18 3.1 Measurement Uncertainty Compliance of the product is based on the measured value. However, the measurement uncertainty is included for informational purposes. The expanded uncertainty (k = 2) for radiated emissions from 30 to 1000 MHz has been determined to be: ±3.5 dB at 10m, ±3.8 dB at 3m The expanded uncertainty (k = 2) for mains conducted emissions from 150 kHz to 30 MHz has been determined to be: ±2.6 dB The expanded uncertainty (k = 2) for telecom port conducted emissions from 150 kHz to 30 MHz has been determined to be: ±3.2 for ISN and voltage probe measurements ±3.1 for current probe measurements Report Number 3091276BOX.001 Page 7 of 18 3.2 Site Description Test Site(s): 2, Parking lot by Site 2 Our OATS are 3m and 10m sheltered emissions measurement ranges located in a light commercial environment in Boxborough, Massachusetts. They meet the technical requirements of ANSI C63.4-2003 and CISPR 22:1993/EN 55022:1994 for radiated and conducted emission measurements. The shelter structure is entirely fiberglass and plastic, with outside dimensions of 33 ft x 57 ft. The structure resembles a quonset hut with a center ceiling height of 16.5 ft. The testing floor is covered by a galvanized sheet metal groundplane that is earth-grounded via copper rods around the perimeter of the site. The joints between individual metal sheets are bridged with a 2 inch wide metal strips to provide low RF impedance contact throughout. The sheets are screwed in place with stainless steel, round-head screws every three inches. Site illumination and HVAC are provided from beneath the ground reference plane through flush entry ports, the port covers are electrically bonded to the ground plane. A flush metal turntable with 12 ft. diameter and 5000 lb. load capacity (12,000 lb. in Site 3) is provided for floor-standing equipment. A wooden table 80 cm high is used for table-top equipment. The turntable is electrically connected to the ground plane with three copper straps. The straps are connected to the turntable at the center of it with ground braid. The copper strap is directly connected to the groundplane at the edges of the turntable. The turntable is located on the south end of the structure and the antennas are mounted 3 and 10 meters away to the nort…
