The test subsystem is able to simulate the variation of the RF signal from the base stations reaching the mobile (as well as the signal from the mobile reaching the base stations) when the mobile is moving at speeds of up to 250 km/h. Serveral variations of this have been developed and produced. The simulator attenuates the simulated Base Station signal through three independent attenuators, then combines the signals. Each attenuator has a dynamic range of 60 dB in 1 dB steps. The operation of the unit is via a RS232 interface, ASCII commands can input parameters into the controller. Upon receiving a trigger the controller executes the program to simulate the link loss to all three Base stations as seen from the mobile transceiver.

RF Simulator Block Diagram TRIGGER: The signal to begin a run can be either a hardware based trigger generated external from the controller, or via RS232 command. If it is desirable to synchronize the beginning of a train run with other external hardware/ software, a hardware based trigger is recommended. The controller will also output a status signal to indicate that the train is running. Once triggered, this signal is active for the duration of the run. OPERATOR CONTROLLED PARAMETERS: Using the RS-232 control interface the operator has the ability to control the following parameters to set up any mobile unit simulation: o Base Station Positions (X meters, A station, B station, C station, + offset from the track), 0-3000 meters for station positions and 10-100 meters for offset from the track. o Mobile Transceiver Start/Stop Position (x , y meters): 0-10, 000 meters. o Mobile Velocity (Y km/hr): 0-250 km/hr BS1 BS2 o Time Resolution (1,10,100,1000 mS or auto to fill memory) BS3 o Frequency: 2 to 6 GHz o Ant Gain for Mobile and Base Station 0 15 30 45 60 75 90 105 120 135 Time, seconds Calculated signal level from each Base Station. 150 o Transmitter Antenna Gain: Receiver Antenna Gain: -10 to +10 dB -10 to +10 dB o Loop Command: Used to simulate the train running in a continuos loop.

These custom designed subsystems provide several parallel, extremely low phase noise conversion paths. Specifically designed low phase noise amplifiers, SRD's and divider circuits result in a superior frequency translation capability. Filters are designed to the customers needs to reduce spurious and harmonic content to extremely low levels. These subsystems use frequency multipliers and mixers to generate a set of phase coherent low phase noise carriers. Through the use of ultra low phase noise oscillators driving distribution amplifiers supply the signals that are multiplied by various N values and combined with mixers to achieve the customer required frequencies with excellent phase noise. A bank of filters block the undesired mixer/multiplier products. Aeroflex PN9000 Phase and Amplitude Noise Test Set (shown above) is used to test Aeroflex / Weinschel Translator designs.

Programmable Attenuators IM3 Performance of Electromechanical & Solid State Programmable Attenuators 0 -10 -20 -30 Passive IM3 Measurement Weinschel Series 4206, 4216, 3200 & 150 Low Carrier Frequency: 869.0 MHz High Carrier Frequency: 891.0 MHz IM3 Frequency: 847.0 MHz -40 Through IM3 (dBm) Some custom subsystem designs warrant the use of Low Intermodulation passive components such as programmable attenuators, terminations, fixed attenuators, couplers, cables, connectors and switches. Aeroflex / Weinschel is a leading manufacturer of the first three items. The following paragraphs briefly describe the importance of low intermodulation and some design features and comparative test data for the same. -50 -60 -70 PIN switched - 4216 series FET switched - 4206 series TO5 rela y switched - 3200 series Edge-line reed switched 150 series -80 -90 -100 -110 Historically the most demanding specifications for programmable components and subsystems have been low insertion loss and SWR, combined with a reasonable life expectancy of several million switching cycles. This was usually adequate for RF instruments like spectrum analyzers and signal generators, where the attenuator bandwidth rather than the switching speed was of prime concern. To achieve wide bandwidths, the programmable attenuators were mostly of electromechanical design and the linearity of these passive components was only taken for granted. Intermodulation distortion discussions and problems were usually limited to components such as amplifiers, mixers and filters. In recent years, however, wireless communication systems employing complex digital modulation schemes, increased channel capacity, high transmit power and extremely low receiver sensitivity have put into question the linearity of passive components. Even very low level multi-tone intermodulation products generated by attenuators can seriously degrade the efficiency of a system/instrument if these products fall within the user passband. For two closely spaced tones at frequencies f1 and f2, the third order IM products at 2f1 - f2 and 2f2 - f1 , are the most harmful distortion products. They are harmful because they are close to f1 and f2 and virtually impossible to filter out. In today's base stations the multi-carrier power amplifier (MCPA) is replacing banks of single-channel amplifiers and their corresponding power combining network. MCPAs have the capability of carrying a number of modulation schemes simultaneously and can also employ schemes such as dynamic channel allocation (DCA) to use the allocated frequency spectrum more efficiently. The in-band intermodulation distortion (IMD) performance of these amplifiers is extremely critical and needs to be measured using low distortion programmable multi-tone generators with superior IMD performance. 158 -120 -130 -140 -150 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 1 1 12 1 3 1 4 15 1 6 1 7 18 1 9 2 0 2 1 22 2 3 2 4 25 2 6 2 7 Input Power, Pin (dBm) each tone Electromechanical programmable attenuators obviously provide a far superior IMD performance than their corresponding solid state counterparts employing semiconductor switching elements. However, their slow switch speed, in the order of milli-seconds, and short switch life in the order of 5-10 million cycles make them unattractive in some applications like cell phone testing and other ATE systems. Solid State programmable attenuators do overcome these two problems and are, therefore, included here for IMD performance comparison. The goal is to provide some good basic IMD test data for a variety of commercial programmable attenuators and permit the end user to select the most appropriate type for his system application. Fixed Attenuators & Terminations These seemingly linear components generate low levels of IMD which must be considered, especially when incident power levels are high. Some of Aeroflex / Weinschel custom subsystem designs include low IM versions of medium and high power fixed attenuators and terminations. These components are supplied with specified 3rd order through and reflected intermodulation levels (IM3) measured with a passive IM analyzer. Typically, the IM3 levels for these components are -110 dBC . Standard Models with this LIM (low IM) option are models 33, 24, 49, 53, 57, 58 and the corresponding terminations, ranging in incident power ratings of 25 to 500 Watts. Features of these components include specifically designed connectors and carefully processed and trimmed thin film resistors for low IM performance. Couplers, Cables, Switches, Connectors, etc. For these other passive components Aeroflex / Weinschel works very closely with our suppliers, providing them pertinent design input to achieve the lowest possible IMD performance on such products. 5305 Spectrum Drive, Frederick, MD 21703-7362 TEL: 301-846-9222, 800-638-2048 Fax: 301-846-9116 web: www.aeroflex.com/weinschel email: [email protected] Revision Date: 3/4/09
