Locating and Isolating Cables :Using MT-7028 Networking Tone & Probe kit to locate and insolate cables using the 1KHz analog, also trace twisted wires (UTP,Cat 5, Cat 5e, Cat 6) and telephone line. Use with a patch cord for RJ45 / RJ11. Coaxial cable, general cable and various wiring boards can be tested by using with alligator clip cable.MT-7028 Transmitter provides two 1 KHz analog toning modes, Hi/Low two-note tone, for location and isolating cables. Both toning signals are available at all connectors on the Transmitter.2. Locating Individual Wire Pairs with the MT-7028 Analog Function To locate cables, do the following steps :1) Connect the black alligator clip of the Transmitter to the ground, andthen connect the red clip to a jack or punch-down block 2) When push , the indicator of “POWER/ BAT LOW” will light upand turn on the power. Push button for cable tracing. When the RED indicator flickers, the low-tone cable tracing is working. Push button again to feature the high-tone cable tracing, the RED indicator will flicker faster. Push button again, the RED indicator will stop and standby for next operation.3) Place the receiver function switch at "scan" or "LED", and push “”on receiver to operate cable tracing function. The tracing sound will be output from speaker. When put on earphone, there will be no sound from speaker, but from the earphone.4) Use the Receiver to find the general location of the tone at a cablerack, patch panel, or behind a wall. In locating mode, the Receiver’s signal status indicator LED will light up, the LED brightnessdepends on signal strength, if the indicator does not light up, there is no signal.5) Adjust the volume control on the receiver to locate the wire pairsfrom 10cm to 30cm. 3. Isolating CablesTo isolate the tone source in the cable bundle or at the patch panel, do the steps as described in the previous section of “Locating Cables”.1) Strip the cable’s shield to a length of between 30 to 45 centimetersand divide the wires into two parts. Do the wire separation to isolate the cables to verify the signal of each part. If the beeper gets louder and LED lights up, you have located the position you are looking for. 2) Adjust the volume control from high low to locate the wire that moredifficult to be identified. Narrowing the length from 30 to 10 centimeters will help to more accurately identify the wire pairs. 3) Repeat the steps of 6 and 7 to isolate the bundled cables. 4. Cable Map Testing :1) Connect the MT-7028 Transmitter or Receiver to RJ45/ RJ11 jacks. 2) Push “”, the indicator of “POWER/ BAT LOW” will light up andturn on the power. Push “” on MT -7028 transmitter for cable mapping and shielded function indication. When the green LED indicator flickers slowly, the slow speed scan is working. Push the “” button again, the green LED indicator flickers faster and the fast speed scan will be operated. Push the “” button again; the product will be standby for next operation.3) Different connectors generate different LED and sound indications• RJ45(8P/8C) LED indication :MT-7028 Transmitter (from 1-8seconds in sequence) is synchronized with the MT-7028 Receiver cable map.• RJ11(6P/6C, 6P/4C, 6P/2C) LED indication :MT-7028Transmitter cable map, 6P/6C each second from 2 to 7 insequence, 6P/4C each second from 3 to 6 in sequence, 6P/2C each second from 4 to 5 in sequence is synchronized with the MT-7028 Receiver cable map. If it encounters an empty line, the indication will cease.4) You can use the MT-7028 Transmitter and Receiver to validate thecable map on RJ11 and RJ45 connectors. The cable map function finds the most common wiring status on twisted pair cabling: good, shorts, opens, and crossed pairs• Good wiring: Each LED that corresponding to an active pinflashes briefly and in a stairway order.• Shorts: If two LEDs turn on for 1 second at the same time,those two pins are shorted together. If more than 2 wires are shorted together, the LEDs for the shorted pins indicate opens. • Opens: If an LED flashes briefly, then no LEDs turn on, that pinis open.• Crossed pairs: If one LED flashes briefly, then another LEDlights for one second, the wire for the first LED is crossed pairs to the pin for the second LED.5) Each LED corresponds to an active pin flashes briefly, it should lightfor about 1 second. The brief flash shows which LED is next in the sequence.5. Live telecommunication equipment and router test:Caution !The feature can only be used for testing cable continuity and opens, cannot be used for cross over and short.1) Connect MT-7028 transmitter and working router by RJ45 cablemap test socket.2)Push button to turn on the power, “POWER/ BAT LOW” indicator will light up. Push button on transmitter to feature cable map function. When the TEST indication green LED flickers slowly, the slow cable mapping is working and the red cable map LED starts scanning. Push button again, the TEST indication green LED twinkles fast, the fast cable mapping is working and the cable map LED starts scanning. Push the button again, the TEST green LED light will be off and the product will be standby for next operation.When the “1~8, G” LED indicator on MT -7028 transmitter lighted one by one, the cable (1~8, G) is good. If any of LED indicators is not lighted, the cable is damaged.6.Coaxial Cable & Continuity Test:DANGER :Before testing, please be sure the power of receiver is OFF.To validate cable shield during cable map tests, do the following as:1) Connect the Transmitter to the circuit. Connect the test leads to thecoaxial cable to be tested.2) Push “” button to turn on the power, “POWER/ BAT LOW”indicator will light up. Push “” button on transmitter for short/ open function, the green LED indicator lights up and the short/ open testing is working. Push “” again, the green LED lights off and the product is standby for next operation.3) When “SHORT” red LED indicator lights up, the cable is connected.(the resistance of cable is less than 300Ω). If the indicator is off, the cable is short or resistance of the cable is over 300Ω . 7.Validating Telephone Service and Polarity :Please follow the following steps to check the polarity of telephone lines: 1) Connect the Transmitter to the circuit. Connect the test leads to thetelephone punch-down blocks, RJ11, and RJ45 jacks.2) Push button to turn on the power, “POWER/ BAT LOW”indicator will light up. Then push to operate the polarity indication feature and the LED indicator will light up. Push the button again to get the product back to standby status. 3) 「POL -/G ,POL +/R 」LED indicator is dual color (Red/ Green). TheLED indicator of the Transmitter indicates the status as below:• Red light :Red test lead at positive (+) polarity ;Black test leadat negative (-) polarity.• Green light :Red test lead at negative (-) polarity ;Black testlead at positive (+) polarity.• No Light :Non service or line fault. 8.NCV (Non-Contact Voltage) Testing :CautionThe feature can be used before locating, isolating, cable mapping to identify if the tested cable is with AC voltage. It can not only help to ensure the safety of user and avoid possible electric shock or personal injury, but also protect the product from being damaged by AC power. 1) Turn the switch to “NCV”, the function is started when the powerindicator is on.2) When doing the NCV testing, place the probe of MT-7028 receiverto the tested cable, the NCV indicator twinkles fast and the buzzer sounds, which means the tested object has AC 90~1000V. If there is no response of indicator and no buzzer sounds, it means the tested object has AC power less than 90V or there is no AC power on it.9.Maintenance & Trouble Shooting :WarningTurn off the Transmitter or Receiver and disconnect all test leads before replacing the battery.CautionTo avoid damaging the case, do not use solvents or abrasive cleansers.

IC DATALBI-39028MAINTENANCE MANUALFORRECEIVER FRONT END MODULE19D902782G5DESCRIPTIONThe Receiver Front End (RXFE) Module amplifies and converts the RF signal to the first IF signal of 70.2 MHz. This is a down conversion process using low side injection. The RXFE module is powered by a regulated 12 volts and draws about 260 mA. The RXFE printed wiring board con-tains the following functional circuits:•Preselector Filter•Preamplifier•Image Rejection Filter•Injection Amplifier•Injection Filter•Double Balanced Mixer•Fault DetectorAll but the Fault Detector circuit in the RXFE modulehave 50 ohm impedance terminations.Printed in U.S.A.U119A704125P1Quad Operational AmplifierU4019A704125P1Quad ComparatorU30RYTUA901201/1Power ModuleCIRCUIT ANALYSISPRESELECTOR FILTERThe received RF sigual (J2) is routed through the Preselec-tor Filter. This filter provides front end selectivity and attenu-ates the potential spurious signals of first conversion.Typically, the filter has an insertion loss of 1.5 dB and an op-erational bandwidth of 19 MHz. The filter is primarily a five-pole dielectric bandpass filter and in the 806-825 MHz range.PREAMPLIFIERThe output from the Preselector is coupled through an im-pedance matching network consisting of L10, C11, and DC blocking capacitor C10 to the base of Preamplifier Q1. Q1 is a broadband common emitter amplifier capable of operating in the 806 to 825 MHz range. The Preamplifier stage is supplied by the regulated +12 Vdc line (VCC1) and draws about 60 mA through R13. It has a low noise figure and high Third Order In-tercept point. Transistor Q2 provides Q1 with a constant volt-age and current source. The bias on Q1 is monitored by the Fault Detector circuit via R40. Capacitors C40 and C41 pre-vent the RF component from entering the fault circuit. The out-put signal is coupled to the Image Rejection Filter via an im-pedance matching network consisting of C12 and L12.IMAGE REJECTION FIL TERFollowing the Preamplifier is the Image Rejection Filter.The Image Rejection Filter is a fixed 3-pole dielectric bandpass filter and can meet the desired image rejection of the 806-825MHz frequency band.INJECTION AMPLIFIERThe local oscillator input (J3) from the Receiver Synthe-sizer is coupled through a DC blocking capacitor C20 to U20which is a MMIC that has about 10dB power gain in the 736-755 MHz range. R20 and R25 provide necessary DC biasing for U20. L20 is a RF blocking inductor.The second stage of the Injection Amplifier, consisting of Q20, Q21, and associated circuitry, is capable of amplifying the injection signal from 10 dBm to +19 dBm in the 736 to 755MHz range. The amplifier is powered by the regulated +12Vdc line (VCC1) and draws about 70 mA through R24. Tran-sistors Q4 and Q7 provide Q3 and Q8 with a constant voltage and current source. The bias on Q20 and U20 is monitored by the Fault Detector circuit via R20, R25, and R24 respectively.Capacitors C42, C43 and C44 prevent the RF component from entering the fault circuit. The output signal is coupled to the Injection Filter via an impedance matching network consisting of C23 and L23.INJECTION FILTERFollowing the Injection Amplifier is the Injection Filter which is a dielectric bandpass filter. It has a bandwidth of 736 to 755 MHz and is used to attenuate the harmonics of the Injection Amplifier. The filter also has an insertion loss of about 2 dB.DOUBLE BALANCE MIXERThe Double Balance Mixer (DBM) is a broadband mixer.It converts an RF signal in the 806-825 MHz range to the 70.2 MHz first conversion IF frequency. The mixer uses low side injection driven by a local oscillator signal of +17 dBm.The mixer conversion loss is typically about 6.0 dB. The IF signal is then coupled to a diplexer, consisting of R30, L30,C30, C31 and L31. Finally, the IF signal is routed to the out-put connector (J4).FAULT DETECTORThe Fault Detector circuit monitors the operation of pre-amplifier and injection amplifier devices. Operational ampli-fiers U40.1 and U40.2 compare the bias on the Preamplifier Q1 to preset levels, while U40.3 and U40.4 compare the bias levels on Injection Amplifiers Q20 and U20.When the bias for Q1, Q20, and U20 is within the preset window limits, the output from the comparators is a high level. This causes Q40 to conduct, turning off Q41 and the fault indicator, CR40. A high level signal is also sent to the Controller on the FLAG 0 line.If the biasing for the amplifiers is not within the proper operating range, the fault detector circuit will pull the FLAG 0 line low. This turns off Q40 causing Q41 to conduct. Q41now provides a ground path for CR40, turning on the fault indicator.Copyright© December 1993, Ericsson GE Mobile Communications Inc.Table 1 - General SpecificationsFigure 1 - Block DiagramLBI-390281MAINTENANCETEST PROCEDUREThe RXFE module has to be tested for Noise Figure, Gain, Third Order Intercept Point, Isolation etc.. With proper current drawing of devices, Bandwidth and Conversion Gain the RXFE module will meet its specifications. The following are test procedures will verify proper Conversion Gain and current drain:1.Supply 12 Vdc to pin 15A, B, C. (1C is ground.)2.Inject the desired RF signal into RF IN at a level of-10 dBm.3.Inject the desired local oscillator signal into LO IN ata level of 0 dBm (LO frequency = RF frequency-70.2 MHz).4.Measure the IF OUT power at 70.2 MHz, the ratio ofRF IN to IF OUT is -2 dB ±1 dB.5.Measure the current drawn by the RXFE module.Typical current drain is 260 mA.PARTS L ISTTROUBLESHOOTING GUIDE*NOTE: For troubleshooting the gain or loss, the RXFE needs to be under the normal operating condition:•I2 Vdc supply.•Inject L.O. power at a level of 0 dBm into LO IN (J3), (LO freq. = RF freq. - 70.2 MHz).•Inject the desired RF signal at a level of -10 dBm into RF IN (J2).•Terminate the IF OUT (J4) with a good 50 ohm impedance.Use a Spectrum Analyzer and 50 ohm probe (with good RF grounding) to probe at the input and output of each stage to check its gain or loss (see schematic diagram).RECEIVER FRONT END MODULE19D902782G5ISSUE 1*COMPONENTS, ADDED OR DELETED OR CHANGED BY PRODUCTION CHANGESLBI-39028 2OUTLINE DIAGRAM RECEIVER FRONT END PWB19D902490G5(19D902490, Sh. 6, Rev. 1)LBI-390283ASSEMBLY DIAGRAM LBI-39028RECEIVER FRONT END MODULE19D902782G5(19D902782, Sh. 3, Rev. 1)4SCHEMATIC DIAGRAMLBI-39028RECEIVER FRONT END MODULE19D902782G5(19D904935, Sh. 1, Rev. 4)5。
