Operational Description

X12-600 Theory of Operation 8/7/01 X12-600 Overview The X12-600 is an ECG amplifier with digital conversion and integrated RF transmitter. The ECG amplifier is a 12 lead device with diagnostic quality digital conversion. The RF transmitter operates in the TV channels 37 through 41 (608 to 632 MHz) meeting FCC Part 15.242. The X12 has a detachable light weight 12 lead patient cable. The X12-600 operates from 2 AA Alkaline batteries for over 30 Hours. When the battery compartment is removed, a power switch and RF channel select switches are exposed. The front panel has a two button keypad and a 51x27 mm segment LCD. The overall dimensions are 140x67x25 mm. The X12 is made up of two circuit boards sandwiched together inside the unit. A single 8 pin header provides interconnectivity. The two boards are the Mortara Front End Card (MFC) and the Mortara Transmit Card (MTC). The MFC is screwed to the back half of the plastic housing. The MTC is screwed to the front plastic housing. The LCD is held in place by the MTC with conductive rubber strips. The rubber strips pass the electrical signals from the MTC to the LCD. Exiting from the top of the unit is a 45mm long antenna. Internal attachment to the PC board is via a standard SMA connector. The antenna is collared by the case thus it is not replaceable unless the case is disassembled. The case mounting screws are hidden by the back label preventing easy removal. The mechanical antenna capture technique is identical to the FCC approved X12-915 (HJR-X12-915). Mortara Front End Card (MFC) The MFC is a low power ECG front end that converts the analog patient signals to digital data. The MFC is designed to operate in handheld or portable devices and to operate from two AA alkaline batteries. The MFC has the patient cable connector mounted directly on the PC board. The digital data and clock interface to the transmit card is through an 8 pin header. There is no isolation boundary required for this board so all signals and power lines connect directly to the transmitter. The two AA Alkaline batteries connect to the MFC through the slide switch. The battery voltage is stepped up to 5 volts by switching regulators U2. This step up supply can operate with the two AA batteries down to ½ volt each. This effectively uses all the energy stored in the batteries. The 5V output is first linear regulated (U3) to 4.3V and then linear regulated (U4) to 3.3V. The 4.3V is only used to power the linear op amps. The 3.3V is 1% accurate and powers the custom A/D converter, voltage references, and other logic components. The linear regulator U3 keeps the MFC in reset until the supply is within operating range. The ECG signals are digitized by a custom 8 channel A/D converter with 20 bit resolution (U1). The A/D is clocked by the 5.12 MHZ clock from the transmit card. The true sample rate for each channel is 10 KHz. A 2.56 MHz serial data stream comprised of all 8 channels encoded in 32 bit packets is sent to the transmit card for processing . Mortara Transmit Card (MTC-600) The X12-600 processing is performed by a Motorola 68HC711 microcontroller on the MTC board. The microcontroller runs at the system clock speed of 5.12 MHz. Besides processing the digital ECG data the microcontroller performs the following tasks. *Writing data to the LCD controller (U13). *Reading the RF channel select switches (S2 and S3). *Reading the key pad. *Activating the speaker tones. *Program the RF oscillator phase locked channel. The two AA Alkaline batteries connect to the MTC through the slide switch. The battery voltage is stepped up to 3.3 by switching regulator U3. This step up supply can operate with the two AA batteries down to ½ volt each. This effectively uses all the energy stored in the batteries. U2 provides a regulation drop out flag that will reset the processor when the 3.3V switcher supply drops below a defined threshold. This condition occurs either at start-up or at battery depletion. Either case, halting the processor prevents transmission of erroneous data or other system malfunction until the supplies are valid. The microcontroller, other logic, and RF oscillator are all powered by the 3.3V supply. The RF oscillator is controlled by a phase locked loop (PLL). The PLL is programmed by the microcontroller based on the channel switch settings. The channel switches and subsequently the channel itself have hexadecimal labels. The lowest channel is 00 and the highest channel is FF. The Table I. below lists the channel numbers and the center RF frequencies. The 2.56 MHz serial data stream from the MFC A/D converter is first processed by U9 the Receiver Gate Array. This device decimates the 10KHz sample rate and formats the data for each sample and channel into two 16 bit words. The effective sample rate out the Receiver is 500 Hz for each channel. The output data is dumped into FIFO’s U7 and U9. When the microcontroller U4 is ready, it reads the data samples from the FIFO’s. The microcontroller processes the ECG data including detecting lead fail. If lead fail is detected the display driver is also informed resulting in the lead fail message being displayed. If in the impedance check mode the microcontroller detects the small stimulus voltages in the data for its magnitude and derives the quality of electrode placement. Finally, the ECG data, lead fail data, error correction, RF channel number, pace maker detect, and ancillary data is formatted into a 40K baud serial data stream. This data stream is Gaussian Filtered then FM modulates the RF carrier with a 20 KHz deviation.

MODEL: X12-600 SERIAL: 30012-006-1000A DESCRIPTION: X12-600 Medical Telemetry Transmitter The X12-600 medical telemetry transmitter was found to MEET the radiated emission specification of Title 47 CFR, FCC Part 15, subpart C, for an intentional radiator. No conducted emissions tests were performed, due to the product not being powered off of the public AC power mains. The X12-600 medical telemetry transmitter was also found to MEET the radiated emission specification of Title 47 CFR FCC Part 15, subpart B for emissions with regards to the class B digital sections of the product. This product is a composite device, with the digital section subject to verification. Therefore this technical report will primary contain data that is pertinent to the certification of the transmitter section of the product. L. S. COMPLIANCE, Inc. FCC ID: HJR-X12-600-15 LSC-Mortara-Medical Tx-301314 Page 5 of 39 1.4 INTRODUCTION On August 9 th , 2001, a series of Radiated Emissions tests were performed on a sample model of the Medical Telemetry Transmitter. The X12-600 is an ECG amplifier with digital conversion and integrated RF transmitter. The ECG amplifier is a 12 lead device with diagnostic quality digital conversion. The RF transmitter operates in the TV channels 37 through 41 (608 to 632 MHz) meeting FCC Part 15.242. The X12 has a detachable light weight 12 lead patient cable. The X12-600 operates from two AA Alkaline batteries for over 30 hours. When the battery compartment is removed, a power switch and RF channel select switches are exposed. The front panel has a two button keypad and a 51x27mm segment LCD. The overall dimensions are 140x67x25 mm. These tests were performed using the test procedures outlined in ANSI C63.4-1992 for intentional radiators, and in accordance with the general limits set forth in FCC Part 15.242 and 15.209 for a low power transmitter. Tests were also performed as outlined in ANSI C63.4- 1992 for non-intentional radiators, in order to allow verification of emissions from the digital section of the product. These tests were performed by Thomas T. Lee, of L. S. Compliance, Inc. and witnessed by Brian Sueppel of Mortara Instruments, Inc. 1.5 PURPOSE The above mentioned tests were performed in order to determine the compliance of the product with limits contained in various provisions of Title 47 CFR, FCC Part 15, including: 15.209 15.242 All radiated emissions tests were performed to measure the emissions in the frequency bands described by the above sections, and to determine whether said emissions are below the limits established by the above sections. These tests were performed in accordance with the procedure described in the American National Standard for methods of measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (ANSI C63.4-1992). Another document used as reference for the EMI receiver specification was the International Special Committee on Radio Interference (CISPR) number 16-1 (1993). 1.6 RADIATED EMISSIONS TEST SETUP The test sample was operated within the 3 meter Semi-Anechoic, FCC listed chamber located at L.S. Compliance in Cedarburg, WI. The test sample was operated using two AA alkaline batteries. The battery voltage is stepped up to 5 volts by switching regulators U2. This step up supply can operate with the two AA batteries down to ½ volt each. This effectively uses all the energy stored in the batteries. The test sample was positioned upon an 80cm high wooden table, which was positioned upon the 2meter turntable within the chamber. The measurement antenna, mounted upon a motorized mast was then placed 3 meters from the product perimeter. This allowed the test sample to be scanned in both azimuth and elevation. Measurements were performed for the transmitter fundamental, and harmonics up through the 10 th harmonic, although harmonics above the 4 th harmonic could not be seen in the noise floor. The test sample was set to operate on one of three channels available within …
