Section 2, Microwave Path Engineering Basics 1. TRACER 4206 System Manual LINE-OF-SITE The TRACER 4106 and 4206 systems are designed for operation in the license free 2.400 to 2.4835 GHz and 5.725 to 5.850 GHz Industrial, Scientific, and Medical (ISM) bands. Radio wave propagation in these bands exhibit microwave characteristics, which are ideally suited for point-to-point, line-of-sight communications.

TRACER 4206 System Manual Section 2, Microwave Path Engineering Basics Where, in the second equation the path loss has been lumped into a single quantity, LP, as discussed previously. When using decibel notation, it is necessary that all quantities are individually converted to decibels prior to performing addition and subtraction. When d is expressed in miles and f in GHz, the path loss expression in decibels becomes L P 96.
Section 2, Microwave Path Engineering Basics TRACER 4206 System Manual lobes, as shown in Figure 2 on page 18. The antenna alignment step to setting up a microwave link is in fact steering the main lobes of both antennas until the main lobe of one transmitter is centered on the receiving element of the receiving antenna. main lobe side lobes Figure 2.

TRACER 4206 System Manual 9. Section 2, Microwave Path Engineering Basics FADE MARGIN Fade margin is a value indicating the amount of extra signal power available to the receiver to operate at a maximum bit error rate (BER). Higher levels of fade margin are better, and will protect the viability of the microwave link against signal fading. For most applications, 20 to 30 dB of fade margin should ensure a reliable link.
Section 2, Microwave Path Engineering Basics TRACER 4206 System Manual The climate factor is a quantity that compensates the link availability for different types of climates (weather). In general, microwave links operating in areas with high humidity will have less availability than those in arid areas, primarily because water is a dispersive mechanism to microwave energy, and causes the main signal lobe to refract and disperse away from the receiver location.

Section 3, Engineering Guidelines 1. TRACER 4206 System Manual EQUIPMENT DIMENSIONS The TRACER 4106/4206 unit is 17.12” W, 9.34” D, and 1.72” H, weighs 7 lbs, and can be used in rack-mount configurations. 2. POWER REQUIREMENTS The TRACER 4106/4206 system has a maximum power consumption of 20W and a maximum current draw of 0.95A (at 21 VDC). 3.
TRACER 4206 System Manual Section 3, Engineering Guidelines TX PWR Monitoring Interface The TX PWR voltage is a function of the selected transmit power level. This voltage ranges approximately from 0 to 5V, with 0V corresponding to +5 dBm (3 milliwatts) and 5V corresponding to +20 dBm (100 milliwatts). Front Panel LEDs With the TRACER 4106/4206 powered-on, the front panel LEDs provide visual information about the status of the TRACER 4106/4206 system.

TRACER 4206 System Manual Section 3, Engineering Guidelines DC Power Connection The TRACER 4106/4206 can operate from a supply between 21 and 60 VDC, with either polarity referenced to ground, and consumes less than 20 Watts (W). Power supplies should be able to provide up to 30 W at the selected voltage. Current required (in amps) is determined by dividing the power consumed (in watts) by the applied voltage (in volts). For example, at 48 V, TRACER 4106/4206 would draw approximately 0.42 A (25 W/48 V).
Section 3, Engineering Guidelines TRACER 4206 System Manual RS-232 Connection (Terminal Use) The RS-232 connector provides a female DB-25 terminal connection (wired as a DCE interface), which is used for terminal access to the TRACER 4106/4206 system. The RS-232 port provides the following functions: • Accepts EIA-232 input from a PC or terminal for controlling the TRACER 4106/4206 system • Operates at 9600 bps Table 6 on page 28 shows the pinout.

Section 6, Troubleshooting Guide 1. TRACER 4206 System Manual OVERVIEW This troubleshooting guide provides recommended actions for various conditions of the TRACER 4106/4206 system. The status LEDs (located on the front panel of the unit) provide information to help determine the necessary troubleshooting action. Recommended actions for resolving possible status LED indicators are contained in this guide. 2.
TRACER 4206 System Manual Section 6, Troubleshooting Guide RF LOW LED If the RF LOW LED is ON (solid Red), it is an indicator that the received signal is within 10 dB (approximately) of the minimum operable signal. This condition is typically indicative of a path problem. Recommended Actions: 1. Verify the far-end transmitter power setting is the value that the link planning budget allows. 2. Check all coaxial cable connectors for solid connections.
Section 6, Troubleshooting Guide TRACER 4206 System Manual Blue Alarm A remote alarm (alarm indication signal or AIS) is generated by the attached equipment. The root cause must be determined at the attached equipment. A typical cause of a blue alarm is a lack of input to a CSU. Recommended Actions: 1. Verify the input to any attached data equipment. BPV Bipolar violations (BPVs) indicate an improper configuration or faulty wiring. Recommended Actions: 1.
