2. The challenge accepted by Tektronix and the NetTek is to provide tools for the majority of circumstances. The kinds of tools needed every day. After more than 1 1/2 years of service, the NetTek is pretty well debugged. The hardware has passed the usual round of shake, vibration and drop tests with flying colors… even launch from a trabuchet (not yet a mil spec. test). More important, it has passed the “field technician daily use test. At this point, hardware issues are rare.The challenge accepted by Tektronix and the NetTek is to provide tools for the majority of circumstances. The kinds of tools needed every day.

3. An Economic Choice So the bottom line is: can we afford to continue to purchase more, and more expensive, service monitors for every new mode? Can we reasonably expect field technicians to remember how to operate instruments they might use once a year? Can we interrupt service when we know the end result will still be “replace-the-board”? NetTek starts out in the form you need today, and grows into the form you need tomorrow… all done in software!So the bottom line is: can we afford to continue to purchase more, and more expensive, service monitors for every new mode?

7. The goal of a wireless communications system is to transfer the maximum amount of RF energy in one direction to achieve desired coverage Garden hose and sprinkler To accomplish this, a wireless communications system must “Match” from an RF standpoint Otherwise, reflections occur Reflections affect the overall performance of our system BTS Master TrainingIntroduction to Line Sweeping - RF Basics Wireless communication systems require the proper integration of several components. For example, antennas are connected to the transmitter/receiver, as well as switching and signal processing equipment by means of a coaxial cable. It is important that these components are “matched” from an RF standpoint, otherwise reflections occur. Reflections affect the overall performance of our system. If the level of reflections becomes excessive, the quality and performance of our system is greatly degraded. Thus, a wireless communications system is similar to connecting several garden hoses together with a sprinkler. If the hoses and sprinkler are properly matched, the sprinkler distributes water to the outside environment, covering the desired area. If not, the sprinkler either dribbles water out to the outside environment (loss of signal power) or doesn’t work at all. Although this example is rather simplistic in form, you get the idea. Just remember that the only good reflection is the one you see when you look at yourself in the mirror!! Wireless communication systems require the proper integration of several components.

8. BTS Master TrainingIntroduction to Line Sweeping - RF Basics What do we mean by “Match” In a RF/Wireless communications system, it is often necessary to connect various components together to deliver the signal from the transmitter/radio to the antenna Cables, connectors, adapters, etc. Each of the components within the system must match “electrically” (typically 50 ?) as we are in essence transferring electrical energy 75 ? ? 50 ? What do we mean by “Match”? From an RF standpoint it is important that we match like things with like things. It is like trying to make sure you have the same color socks on in the morning. Finding out later that you have one blue and one brown sock on is quite a shock. In this sense, there is a definite clash, just as if you connected a coaxial cable with a 75? impedance to one with 50?. Why is this important? Well, in RF systems (wireless systems) the various components that comprise the system each have a characteristic impedance (transmitter/receiver, cable, connectors, antenna, etc.), typically 50?. If we connect all our components together, each having the same 50? impedance, our system will transfer the maximum amount of signal energy. If our system is not properly matched (meaning that our components all exhibited different characteristic impedance's), reflections will occur and the performance of our system will be degraded significantly. Let’s go back to our garden hose example. Lets say that we properly matched the various sections of our garden hose to our sprinkler, all with the same, constant resistance. Our result would be a nice flow of water out of the sprinkler, covering the desired area. On the other hand, say we connected several very large-diameter sections of our garden hose to several sections with a very small-diameter. In this case we would in effect have varying resistances within our system, resulting in some of the water to be back-flowed back to where it came from. Obviously this is not a desirable result. Additional info Impedance is essentially the RF/Microwave version of resistance, and is perhaps the most critical component of a transmission line. What do we mean by “Match”?

9. BTS Master TrainingIntroduction to Line Sweeping - RF Basics What do we mean by reflection? Reflections result from component mismatches. This causes the RF signal to be “reflected” back to where it came from. Let’s go back to our garden hose example again. In this example, a reflection occurs when you take a 1-inch diameter garden hose and hold it up against a 3/4-inch hole- you immediately understand what reflected energy is all about when you turn the water on! Whatever amount of water that cannot fit into the hole will find somewhere else to go. In the case of the hole, the water is more likely to spray back into your face. Again, this is extremely simplified definition of a very important concept. Since the RF signal travels through the transmission line (coaxial cable) similar to that of water in our garden hose example, any imperfections or mismatches will cause a disturbance in the signal “flow,” resulting in the signal to be “reflected” back to where it came from. Remember, our goal is to efficiently transmit the maximum amount of RF/Microwave energy, for example, water through the garden hose and ultimately the sprinkler. This occurs when the RF signal energy is flowing in one direction only; either from the transmitter to the antenna, or from the antenna to the receiver. Reflections result from component mismatches.

10. BTS Master TrainingIntroduction to Line Sweeping - RF Basics How can we tell if our system has a reflection or is not meeting specified performance? Two types of measurements VSWR Measurement Return Loss Measurement VSWR and Return Loss Measurements provide a quick pass/fail measurement of a wireless system. Two basic measurements can be used to determine the performance of your communications system. These are the Standing Wave Ratio (also referred to as VSWR) and Return Loss. Mathematically, you can calculate one from the other. However, let the test equipment do the conversion for you, or use a cheat sheet! Think of the old days, when all you had was the Bird Wattmeter or similar. Two basic measurements can be used to determine the performance of your communications system.

11. BTS Master TrainingIntroduction to Line Sweeping - RF Basics This table compares various values of VSWR and Return Loss. It is merely an example to illustrate that VSWR measurements are unit-less and are measured in terms of X:1, wherein the lower the value of “X”, the better the measurement. Conversely, Return Loss measurements are measured in terms of dB and the higher the return loss value, the better the measurement. This table compares various values of VSWR and Return Loss.

14. BTS Master TrainingLine Sweeping Fundamentals  Must have three pieces of information to properly conduct a line sweep 1. Frequency Range This can be determined from your system specs Make sure that your antenna matches the specified frequency range 2. Cable Type(s) This can be determined from your system specs Make sure that your cable(s) match the specified cable type 3. Distance of Cable Run This is not always outlined in your system specs, but is important For less experienced line sweepers, it is suggested that you draw out the system before conducting a line sweep Identifying the problems in a cable and antenna system.
