PCS MCPA Top Level Alignment Procedure Page 1 of 12 PCS MCPA Top Level Amplifier Alignment Procedure (Version 1.7) December 6, 2001 Rev 1.7 PCS MCPA Top Level Alignment Procedure Page 2 of 12 1 Purpose: The intent of this document is to describe the specifics of a method to tune and align the PCS MCPA Power Amplifier. This procedure is based upon the Universal Method proposed by Steve Avis. At the beginning of the procedure the operator (engineer, technician or otherwise) will have an un-tuned, complete assembly. If the unit successfully passes through the procedure the assembly will be a fully tuned and functional unit. 2 Outline: This document is divided into 4 major sections to show below. The document will elaborate on each step, giving step-by-step instructions for all portions of the procedure. PROCESS STEPS: I. Prep Check connections and quality of assembly Set default settings for each of the loops II. Network Analyzer Measurements Small signal alignment of Loop1 Small signal alignment of loop2 III. Spectrum Analyzer Measurements Verification of proper Loop1 Carrier Cancellation Verification of proper Loop2 performance/targets IV. Detector Calibration and Alarm settings 3 Procedure 3.1 Prep 3.1.1 Inspection Inspect all RF and DC connections for proper installation. [Refer to the AI-02-000174] Make sure all DC connections are present and firmly plugged in. Make sure all RF cables are installed and firmly plugged in. 3.1.2 Setting Defaults A. Start the GUI B. Attach the cable adapter to the RF/DC connector on the PA. Affix with 4 screws to secure the connection. C. Disconnect RF in from the unit, at the input to the preamp. PCS MCPA Top Level Alignment Procedure Page 3 of 12 D. Set Power Supply to +27V. When brought up, the unit should have about 19.3A of current. (18.6 - 21.5 A spec range) E. Measure the voltage at points and insure the voltage is 27±.1 Vdc F. On the GUI Hit “Cal DC” The DC input should read 26.97V on the GUI. G. Hit “Disable” on the GUI (Note: The fans will turn off when this is done). Unit should be drawing 0.9-1.1A H. Open the “Loop1” window and with Loop1 disabled, and Manual control set to ON, set the DAC Sliders On Loop1 to the following setting: Slider NameSlider Value PA275 PP512 L1A2210 L1P3512 L1A190 L1P1120 Measure voltage between these 2 points Disconnect input cable here. PCS MCPA Top Level Alignment Procedure Page 4 of 12 L1P2120 L1P4“ON” Insert a picture of the GUI 1. Click on <Save to Flash> 2. Click on <Revert> 3. Click on <Manual Control> OFF then <Manual Control> ON to make sure the values got stores. 4. Hit quit and go back to main GUI screen when done. I. Open the “Loop2B” window, 1. make sure Loop2 is disabled, 2. manual control is ON and 3. set the DAC Sliders On Loop2 to the following settings: Slider NameSlider Value L2A2210 L2P3512 L2A190 L2P2120 L2P1120 L2P4“ON” Insert a picture of the GUI 4. Click on <Revert> 5. Click on <Manual Control> OFF then <Manual Control> ON to make sure the values got stores. 6. Hit quit and go back to main GUI screen when done. Finished with Initial Setup – Go to next section! 3.2 Network Analyzer Measurements 3.2.1 Loop 1 Carrier Cancellation Alignment Steps 1. From the Main GUI enable the amplifier 2. Select the Loop 1 GUI 3. In the lower left hand corner of the GUI are the Main amp and Error amp controls. Select off for these amplifiers and click on <Change>. Current should be 6.3-7.2A (6.9A typ). 4. Select <Disable> for the loop. 5. Recall “Loop1” calibration on network analyzer – the calibration should be from 1910MHz to 2010MHz. Note that the measurement bandwidth is 1930-1990MHz in this case. 6. Connect the VNA port 1 to the input to the preamp (if applicable) and port 2 to the output of the carrier cancellation board. (insert a photo here) 7. Disconnect the main path sample cable from J9 and terminate that port in 50 ohms. 8. Go into the manual mode (Manual mode ON) PCS MCPA Top Level Alignment Procedure Page 5 of 12 9. Measure the reference delay path from 1930-1990MHz. Use split screen display on VNA to measure gain and phase at the same time. Set Marker 1 to 1930MHz, Marker 2 to 1960MHz, Marker 3 to 1990MHz. Phase, Channel 1, scale=2°/div, buttons sequence. a) Make Marker 2 active (1960MHz) b) Press <Marker Function>, <Marker to delay>, <Marker to reference> c) <Scale>, <Electrical delay> d) Adjust delay for flattest phase response 1930-1990MHz (scale 2°/div), <Marker to reference> e) Peak to peak flatness should be less than 2 degrees, if it is more than 2 degrees, then there is something wrong with the reference path – move the unit to the troubleshooting area and mark the test as FAIL and indicate REFERENCE PATH PHASE FLATNESS OUT OF SPEC. f) <Display>, <Data to Memory>, <Data – Memory> g) <Scale>, <phase offset>, on the keypad put in 180 and hit the <x> button. Gain, Channel 2, scale=.2dB/div, buttons sequence. a) <scale>, <marker to reference> b) Using R279 adjust the loop 2 gain slope adjuster for optimum flatness. c) Repeat step a). ** Peak to peak flatness should be less than 1.0dB, if it is more than 1.0dB, then there is something wrong with the reference path – move the unit to the troubleshooting area and mark the test as FAIL and indicate REFERENCE PATH AMPLITUDE FLATNESS OUT OF SPEC. Disconnect this cable (J1) and insert test cable from port 1 of the vector Network Analyzer Disconnect this cable (J10) and insert test cable from port 2 of the vector Network Anal yzer PCS MCPA Top Level Alignment Procedure Page 6 of 12 <Display>, <Data to Memory>, <Data – Memory> 10. Reconnect the main path sample cable to the carrier cancellation board. 11. Enable main amplifier (Loop1 -> Main Amp ON, Error Amp OFF) 12. Using manual gain slider (L1A1) adjust gain to reference value. Use the Loop1 slope adjustment (R34) if necessary to match gain flatness with reference path. This must be done prior to adjusting the phase as it can modify the delay. Main Path should have a flatness of less than 1.0dB peak…

This document may be altered or revised by Compliance Certification Services personnel only, and shall be noted in the revision section of the document. TEST PROCEDURE 1) Three balanced signals were applied to the RF input. One set as close as possible to the bottom of the block edge and one set as close as possible to the top of the block edge. Set the RES BW to 1% of the emission bandwidth to show compliance with the –13dBm limit, in the 1 MHz bands immediately outside and adjacent to the top and bottom edges of the frequency block. 2) For the Out-of-Band measurements a 1 MHz RES BW was used to scan from 15 MHz to 10fo of the fundamental carrier for all frequency block. A display line was placed at –13dBm to show compliance. RESULT The following table indicates the plot number associated with the Input Bandwidth, Output Bandwidth, Block Edges, Intermodulation and Out-of-Band emission plots. All measurements are in peak detector mode.

On a test site, the EUT shall be placed on a turntable, and in the position closest to the normal use as declared by the user. 2). The test antenna shall be oriented initially for vertical polarization located 1m from the EUT to correspond to the frequency of the transmitter. 3). The output of the test antenna shall be connected to the measuring receiver and either a peak or average detector was used for the measurement as indicated on the report. The detector selection is based on how close the emission level was approaching the limit. 4). The transmitter shall be switched on, if possible, without the modulation and the measurement receiver shall be tuned to the frequency of the transmitter under test. 5). The test antenna shall be raised and lowered through the specified range of height until a maximum signal level is detected by the measuring receiver. 6). The transmitter shall than be rotated through 360° in the horizontal plane, until the maximum signal level is detected by the measuring receiver. 7). The test antenna shall be raised and lowered again through the specified range of height until a maximum signal level is detected by the measuring receiver. 8). The maximum signal level detected by the measuring receiver shall be noted. 9). The transmitter shall be replaced by a substitution antenna. 10). The substitution antenna shall be oriented for vertical polarization. 11). The substitution antenna shall be connected to a calibrated signal generator. 12). If necessary, the input attenuator setting of the measuring receiver shall be adjusted in order to increase the sensitivity of the measuring receiver. 13). The test antenna shall be raised and lowered through the specified range of the height to ensure that the maximum signal is received.
