IPMobileNet would like to conference call to resolve any open issues this afternoon. -----Original Message----- From: Mike Kuo [mailto:[email protected]] Sent: Wednesday, June 04, 2003 6:07 PM To: 'Les Payne'; Anne Liang; Mike Kuo Cc: Jim Lukes (E-mail); Erik Tanner (E-mail) Subject: RE: IP MobileNet Inc, FCC ID:MI7-IPM4748, AN03T2870 Hi Les: Reply to question #1: Please provide the spectrum plots with RBW greater than the occupied bandwidth. Please do not use calculation to justify the real output power. The real output power is a specified. normaly, you would use a CW signal to determine maximum output power. This transmitter cannot generate a straight CW signal. It can only generate a modulated data signal as referenced in all of our plots. What we did to confirm maximum output power for you was to connect the unit to a power meter and verify the output power. readings using a power meter were 1 db above the readings referenced on the plots in the report. Reply to question #2: O.K. Reply to question #3: Your statement does not agree with the test block diagram. What is the data rate used during the tests ? Please provide the spectrum plots with CW modulation and with data modulation. Reference answer in number one above. Reply to question #4: The statement used to justify radiated spurious emissions is not acceptable. Through out the FCC/TCB training, FCC has made it very clear that substitution measurement procedures per TIA/EIA 603 procedures shall be used for licensed transmitter. 15.209 worst case is not a issue in this case. Please provide radiated spurious emission test data per TIA/EIA 603. This is top confirm that the substitution method per TIA/EIA 603 was used for these measurements. New Plot supplied Reply to question #5: The limits for section 90.214 is T1:25kHz; t2:12.5kHz,; t3:25kHz. Please indicate your measured value on the plots so the max. freq. difference can be verified. I am in the process of drawing in the limits to the plots that were supplied and I should have them to you shortly. Best Regards Mike Kuo -----Original Message----- From: Les Payne [mailto:[email protected]] Sent: Wednesday, June 04, 2003 1:27 PM To: Anne Liang (E-mail); Mike Kuo (E-mail) Cc: Jim Lukes (E-mail); Erik Tanner (E-mail) Subject: FW: IP MobileNet Inc, FCC ID:MI7-IPM4748, AN03T2870 Greetings Mike, Please review answers to questions below. If you require any additional information please let me know. Kindest regards Les ------------- Question #1: The rated output power of this device is 40W but the measured output power at nominal voltage is 31.62W. 13.8Vdc for all tests supplied by a clean dc source. The rated output power for this radio is 40 W, and was producing 40 watts during testing. The measurement noted on page 30 of the test results was taken with a spectrum analyzer using a marker measurement with the resolution bandwidth set to 3 kHz. The radio was modulated at 4.6 to 5.0 kHz. There for the power over the occupied bandwidth would be 44.7 (@ 477 MHz) plus 10log(4.6kHz/3kHz) or 44.7 dBm + 1.85 dB = 46.55 dBm or 45 watts. Please indicate the nominal voltage used during the output power measurement and provide additional output power measurement with DC voltage varied +/- 15%. 13.8 Nominal VDC Temp (C) Voltage Frequency (MHz) Deviation (kHz) Output Power 20 11.7 470.909 0 31.5W 20 13.8 470.909 0 31.6W 20 15.9 470.909 0 31.6W Question #2:What is the channel spacing of this device used ? Channel spacing is 25 kHz Question #3:Occup. BW \ Emission Mask tests: As indicated in page 28 ( test block diagram ) of test report, there is not data modulation used during the tests. Please provide additional occupied BW plots with max. data transmission. EUT was transmitting in accordance with the manufacturer and communications was monitored. Plots as supplied are transmitting worst case transmissions Question #4: Radiated spurious emission tests: 15.209 limits are used as referenced technical limits. This is FCC Part 90 device and 15.209 is for Part 15 subpart C device which is not applicable to this device. In addition, for all licensed transmitter devices, radiated spurious emission shall be made with substitution method per TIA /EIA 603 measurement guideline. Substitution method is not a filed strength measurement. Please provide additional radiated spurious emission measurement with substitution method. The 15.209 limits were used because there were no descernible radiated spurious emissions observed above the ground floor of the spectrum analyzer. Since the 15.209 limits are the "worst case" limits it was deemed appropriate. This has been acceptable to the FCC in the past. Question #5: Transient frequency behavior test (90.214): please provide the test procedure that was used while doing the tests. The test data plots provided do not have any reference level. Please indicate what is t1/t2/t3 setting and reference level. The Transient frequency behavior test is performed per TIA/EIA 603. Test conditions: The RF port of the EUT is connected to a combiner which combines an audio signal (1kHz, +- 5 kHz deviation) from an audio source the combined signal is connected to the input port of a spectrum analyzer. The audio monitor output of the spectrum analyzer is connected to CH1 of an Oscilloscope. Channel 2 of the Oscilloscope is connected to the TX high test point of the EUT. The transient time under investigation is to be the transistion time of the TX high to complete silence of the 1 kHz to (attack) and the transition time of the TX high to complete recovery of the 1 kHz tone for release time. T1 = +- 25 kHz 10 ms T2 = +- 12.5 kHz 25 ms T3 = +- 25 kHz 10 ms

SECTION 1: THEORY OF OEPRATION IPM4748-FCCRpt.doc Page 1 ? General Block Diagram General Block Diagram Definitions For increased data security, the modem supports the Federal Government developed Digital Encryption Standard (DES) data encryption and decryption protocols. This capability requires installation of third party, Internet Protocol (IP) compliant DES encryption and decryption software on the system. The IPM4 mobile radio is comprised of two (2) circuit boards, the digital board and the RF board. The digital circuit board contains the following sections: Input/Output Circuitry associated with the radio’s DB9 data connector providing all the RS232 data and handshake functions, including the necessary level changes. Microcontroller Manages the operation of the radio, the modem, and determines which receiver provides a better signal from a given transmission. Also provides transmit time-out protection in the event a fault causes the radio to halt in the transmit mode. Modem Converts serial data into an analog audio waveform for transmission and analog audio from the receiver to serial data. Within a single chip it provides forward error detection and correction, bit interleaving for more robust data communications, and third generation collision detection and correction capabilities. Power Supply The power supply creates the various voltages required by the digital portion of the mobile radio. SECTION 1: THEORY OF OPERATION The RF circuit board contains the following sections: Transmit Processing Circuitry that amplifies the analog audio signal from the modem and uses it to modulate the voltage controlled oscillator (VCO) and 10 MHz reference oscillator in the injection synthesizer section. Modulating the VCO and reference oscillator simultaneously results in a higher quality FM signal. Injection Synthesizer Provides programmable, ultra stable signals for the radio. Synthesizer incorporates phase lock loop technology used for both receiving and transmitting. Injection In the receive mode, the synthesizer provides a local oscillator signal of 45 MHz above or below the selected receive channel frequency. Transmitter Consists of an exciter and power amplifier module. The transmitter covers the various frequency bands in segments. A different power amplifier module is required for each segment. The transmitter circuitry includes a T/R switch switching the antenna between transmitter and receiver 1 (TX/RX1). Receiver 1/Receiver 2 Required to support the mobile DRS; two (2) discrete receivers are tuned to the same channel and use two (2) antennas. The receivers are double-conversion superheterodyne with a first Intermediate Frequency (IF) of 45 MHz and a second IF frequency of 455 KHz. Each receiver consists of bandpass filters, an RF amplifier, a MMIC mixer, crystal filters, and a one-chip IF system. The injection synthesizer provides the first local oscillator signal. Outputs from each receiver include RSSI and analog audio for the baseband routing circuitry and modem. Power Supply Consists of circuitry that derives the various operating voltages for the RF portion of the mobile radio. SECTION 1: THEORY OF OPERATION ? IPM4 Mobile Radio Section Descriptions The IPM4 Mobile Radio works within a frequency range of 470 to 480 MHz and requires a 1/4-wavelength antenna. This section provides detailed descriptions of each of the sections within the IPM4 Mobile Radio. Refer to Appendix A to view the IPM4 Mobile Radio Circuit Board Diagram. Microcontroller (refer to schematic on page 26 & 27) The microcontroller (U30) is a major component of the radio as it manages the operation of the radio. It also controls the operation of the modem, and determines which receiver provides a better signal from a given transmission. It provides transmit time-out protection in the event a fault causes the radio to halt in the transmit mode. It utilizes a reduced instruction set computer (RISC) architecture which provides low power operation and a powerful instruction set. Other features include a watchdog timer, serial universal asynchronous receiver/transmitter (UART), two 8-bit timers, and 2 KB of electrically erasable programmable read only memory (EEPROM) storage. NOTE : The EEPROM Random Access Memory (RAM) stores the setup data entered by the technician even if there is a loss of power. Support circuitry The support circuitry consists of the following: ??A Supervisor Control Chip (U25) provides power-on reset. ??The clock controls microcontroller operation and is generated by crystal Y3 and a Pierce oscillator circuit (inside the U30-microcontroller). ??The latch (U28) decodes low order address bits (A0-A7) from the address/data bits (AD0-AD7). It is controlled by Address Latch Enable (ALE) output of U30 and the bits are used by the modem. ??A 512Kx8 Static RAM Chip (U31) provides temporary storage of the radio’s configuration data facilitating the technician with access to make changes. ??Control logic is also an important part in the microcontroller section. The RAM chip select (RAMCS*) and modem chip select (MODEMCS*) command lines are created by U26A, U27BCD, and U44ABC. These gates decode four (4) high order address bits (A11-A15). The RAM is addressed by five (5) memory addresses (MA14-MA18) bits decoded by U26D, U27A, and U24. This logic decodes port address bits (PA14-PA18) to produce memory address bits (MA14-MA18) for the RAM chip. Input/Output (refer to schematic on page 28) Input/output components convert serial and handshake data from the modem section to RS232 levels, and vice-versa. Chip U22 is an RS232 transmitter and receiver. It converts data in 5-volt logic form to data in +/-12-volt form, as required by the RS232 standard. A charge pump power supply on the chip converts the +5-volt DC logic power on pin 26 to the +12-volt and –12-volt levels required. Capacitors C106-C109 generate these voltages by a charge pump. These values determine the operating voltages. SECTION 1: THEORY OF OPERA…
