To: Bill Graff From: Greg Snyder Date: 3/27/01 Reference: FCC ID: M7G-HUHF800-40 1.) All amplifiers will need the three tone intermod test. This has been FCC policy for years. R. This unit is only used as a single channel amplifier and therefore the IM test is not required. See e-mail excerpt from Frank Coperich below: From: Frank Coperich [mailto:[email protected]] Sent: Wednesday, March 21, 2001 11:08 AM To: [email protected] Cc: Raymond Laforge Subject: Re: Question on Amplifier Testing The (three tone) IM test does not apply to single channel amplifiers. 2.) Transmitter radiated spurious must be done using the substitution method as described in TIA/EIA 603, and not just a field strength measurement converted to ERP. R. Radiated spurious emissions have been measured using the signal substitution method. See revised report dated 3/27/01. 3.) The measured power output on the 731 does not seem to track with the power output listed in 3.1. Voltage vs. power is not necessarily a concern, therefore testing at anything other than STV (Standard Test Voltage) is confusing. Is this variation in power due to the characteristics of the exciter or the amp? A table including the output power of the exciter feeding the amp on this table is helpful. R. The output power was re-measured with and a new data table has been inserted in the revised report dated 3/27/01. The input signal was also verified to be at a level of 2 watts for each frequency. 4.) It is useful to include unmodulated plots with all Occupied Bandwidths. Ideally, unmodulated plots would always be set to the top of the reference level before modulation applied. As a bonus, if the cable and attenuator loss are placed into the spectrum analyzer offset, then Reference Level would equal power output in dBm. R. Future submissions will include the unmodulated signal with the Occupied Bandwidth plots. 5.) No RF exposure information is included. There are no instructions as to where this device could be installed. Therefore, it cannot even be identified properly as either Fixed or Mobile. Please address. R. The amplifier is used as fixed basestation applications.

Lavorata Compliance Engineer Date: January 17, 2001 EMR Corporation M7G-UHF 450-70 WLL Project # 4717X 3 FCC CERTIFICATION REPORT For EMR Corporation 1.0 Introduction This report has been prepared on behalf of EMR Corporation in support of their application for FCC Certification under Part 90 of the FCC Rules and Regulations. The Equipment Under Test was a Rack Mounted UHF Power Amplifier (Model: HUHF 800-40). All measurements were performed at Washington Laboratories, Ltd. test center in Gaithersburg, MD. Site description and site attenuation data have been placed on file with the FCC's Sampling and Measurements Branch at the FCC laboratory in Columbia, MD. Washington Laboratories has been accepted by the FCC and approved by NIST NVLAP (NVLAP Lab Code 200066-0) as an independent FCC test laboratory. Measurements were made on the Equipment Under Test in accordance with FCC Rule Part 2, specifically the requirements stipulated in: 2.1046 RF Power Output 2.1047 Modulation Characteristics 2.1049 Occupied Bandwidth 2.1051 Spurious Emissions at Antenna Terminals 2.1053 Field Strength of Spurious Radiation 2.1055 Frequency Stability All results reported herein relate only to the item tested. This report shall not be used to claim product endorsement by NVLAP or any agency of the US Government. The measurement uncertainty of the data contained herein is ±2.3 dB. Refer to Appendix A for Statement of Measurement Uncertainty. 1.1 Summary The UHF Amplifier complies with the technical requirements of Part 90 of the FCC Rules and Regulations. 2.0 Description of Equipment Under Test (EUT) The UHF Amplifier series is intended for use in commercial communication systems. Applications include land mobile repeaters, trunking, and data systems. The amplifier is a 40-watt power amplifier operating in the frequency range of 850-875 MHz. The amplifier is powered by an externally supplied 13.6 VDC power source. Testing was performed at the low, middle, and high frequencies of operation for the amplifier. EMR Corporation M7G-UHF 450-70 WLL Project # 4717X 4 3.0 Test Configuration 3.1 RF Output Power (FCC Rule Part 2.1046) A 2 Watt unmodulated carrier signal was connected to the input of the UHF amplifier. The output from the amplifier was connected to a 40 Watt attenuator and then to the input of an HP 8564E RF Spectrum Analyzer. The analyzer offset was adjusted to compensate for the 40 dB attenuator. The RF output power across a 50 ohm load termination was measured directly by the analyzer. The following table lists the measured output power. Frequency (MHz) Input Power to Amplifier Power Output at Nominal Voltage (13.6 Vdc) 850 2 Watts 40.7 Watts 862 2 Watts 38.9 Watts 875 2 Watts 44.7 Watts 3.2 Modulation Characteristics (FCC Rule Part 2.1047) The EUT is an amplifier only and contains no circuitry to modify the RF signal supplied from an approved radio. Only the power level will be raised. 3.3 Occupied Bandwidth (FCC Rule Part 2.1049) A 2 Watt, 2.5 kHz FM modulated signal with 5 kHz FM deviation was connected to the input of the amplifier and the occupied bandwidth observed. A plot depicting the Occupied Bandwidth of the input signal followed by a plot showing the Occupied Bandwidth of the amplifier signal are shown in Figures 1 and 2. EMR Corporation M7G…
