American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 27, 2005 RE: Vyyo Inc. FCC ID: PBJV284 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please provide an internal photograph #5 with all shields removed. 2) Please explain how the 75 to 50 ohm conversions were taken into account in any testing done with a direct attachment to the antenna port (i.e. power, conducted spurious, bandedge etc.). The concern is that many measurements are marginal to limits, and typically the insertion of a minimum-loss pad (75 to 50 ohms) requires a correction of about 5.72 dB. 3) Please explain how power output was calibrated in terms of RMS equivalent voltage according to 27.50(c)(4). 4) Users manual should contain antenna installation instructions regarding RF exposure conditions necessary for the installer/user to be in compliance with RF exposure requirements and/or any co- location limitations. Please update. 5) Please define and justify the use of the emissions designators given on the 731. Note that the measured bandwidths appear different than on the 731. Additionally, please clarify which is intended for QPSK and which is intended for QAM. 6) Please provide both current and voltage applied into the several elements of the final radio frequency amplifying device for normal operation over the power range per (2.1033(c)(8)). 7) FYI....The AC power conducted emissions appear to have an extension between the LISN and Adapter. Generally every effort should be made to plug the adapter as close to the LISN as possible. Please be careful of this in future applications. Timothy R. Johnson Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application.

HERM O N LA BO RA TO RIES November 8, 2005 American TCB 6731 Whittier Ave Suite C110 McLean, VA 22101 Attn: Mr. Timothy Johnson, Examining Engineer RE: your e-mail dated October 27, 2005; Vyyo Ltd. FCC ID: PBJV284, ATCB002867 Dear Mr. Johnson, Please find below the answers to your questions. 1) The revised file “Internal_photographs_16109_rev1” with additional photograph #6 of Tuner without shields was uploaded on November 8, 2005 via Internal Photographs folder. 2) We didn't use any impedance matching network as it is problematic to find one to cover the entire frequency band of measurements (up to 10 th harmonic). We used attenuator to improve return loss and added correction factor of 1.9 dB to spectrum analyzer readings to compensate voltage division between 75 Ohm source and 50 Ohm load. 3) There is no true RMS detector in the spectrum analyzer we used for the test as well as in the most spectrum analyzers of Agilent. Peak detector was used for testing. The peak detector is calibrated in terms of equivalent RMS voltage/power of the envelope detector . 4) The revised “User_Guide_16109_rev1” with corrected Section 3 “Using the Modem” was uploaded on November 8, 2005 via “Users Manual” folder. 5) We used the Emission Designator notation for the maximum channel BW (3.2 MHz), for both 16QAM and QPSK. The Emission Notation is 3M20D1W for 3.2 MHz 16QAM, and 3M20G1W for 3.2 MHz QPSK. The user has several Symbol Rate options (2560, 1280, 640, 320, 160 Ksps), which are related to maximum channel BW (3200, 1600, 800, 400, 200 KHz), for both QPSK and 16QAM. The actual measured occupied BWs were bellow the maximum channel BW for all channel BW and modulation. 6) Please refer to the document “RF_specifications_16109”, page 1, Table “General”, Power Amplifier: 6 V, 650 mA. 7) Thank you for help. Sincerely, Marina Cherniavsky, certification engineer Hermon Laboratories

HERM O N LA BO RA TO RIES November 15, 2005 American TCB 6731 Whittier Ave Suite C110 McLean, VA 22101 Attn: Mr. Timothy Johnson, Examining Engineer RE: your e-mail dated November 14, 2005; Vyyo Ltd. FCC ID: PBJV284, ATCB002867 Dear Mr. Johnson, Please find below the answer to your question. 1). The 1.9 dB voltage division correction factor generally represents the worst case for ideal source, internal impedance 75 Ohm and load. In this configuration the difference between measurements at 50 Ohm and 75 Ohm loads will be expressed by the following equation: V@50 Ohm / V@75 Ohm= Vemf(50/(75+50))/ Vemf(75/(75+75))= 0.8 or in logarithmic units 20 log 0.8 = -1.9 dB. For power correction the situation is even better: P@75 Ohm (dBm) = V@75 Ohm (dBuV) - 108.7 dB P@50 Ohm (dBm) = V@50Ohm (dBuV) - 107 dB Assuming the correction factor will be added, we obtain P@50 Ohm (dBm) = V@50 Ohm (dBuV) - 107 dB - 1.9 dB = V@50 Ohm (dBuV) - 108.9 dB or 0.2 dB correction. The similar corrections used in ESA series of spectrum analyzers from Agilent for 50 and 75 Ohm inputs. The 75 Ohm to 50 Ohm direct transaction corresponds to VSWR=1.5 or 0.2 reflection coefficient. The most of spectrum analyzers yields the same VSWR, so generally saying this is still uncertain will it give the result closer to the "true" one or not. Moreover, the VSWR of the EUT output port is not considered at all, which may be much higher than at the spectrum analyzer input. That is why, we used VSWR=1.5 0.2 reflection coefficient for spectrum analyzer and VSWR=2 0.33 reflection coefficient for EUT antenna port in the measurement uncertainty calculations. These parameters fully cover the range of measurements. Sincerely, Michael Nikishin, EMC& Radio group leader Hermon Laboratories
