Adjusting the softpot value sends information to the radio to increase or decrease the voltage in the corresponding circuit For example left clicking the UP spin button in the New Softpot Value scroll box on the Reference Oscillator screen instructs the radio s microcomputer to increase the voltage across a varactor in the reference oscillator which increases the frequency In ALL cases the softpot value is just a relative number corresponding to a digital to analog D A generated voltage in the radio Perform the following procedures in the sequence indicated NOTE Some of the following screens may vary depending upon the radio under test and the version of tuner software you are using Refer to the software s online help A When keying the radio during a test always transmit into a dummy load Caution Reference Oscillator Alignment Adjustment of the reference oscillator is critical for proper radio operation Improper adjustment will result not only in poor operation but also in a misaligned radio that will interfere with other users operating on adjacent channels For this reason the reference oscillator should be checked every time the radio is serviced or once a year whichever comes first The frequency counter used for this procedure must have a stability of 0 1 ppm or better 6881094C12 A November 11 2004 5 4 Radio Alignment Procedures Transmitter Alignments NOTE Reference oscillator alignmen

This chapter provides a detailed circuit description of the SSE 5000 transceiver and VOCON boards When reading the theory of operation refer to the appropriate schematic and component location diagrams located in the back of this manual This detailed theory of operation can help isolate the problem to a particular component The SSE 5000 radio is a dual mode digital analog microcontroller based transceiver incorporating a digital signal processor DSP The microcontroller handles the general radio control monitors status and processes commands input from the keypad or other user controls The DSP processes the typical analog signals and generates the standard signaling digitally to provide compatibility with existing analog systems In addition the DSP provides digital modulation techniques utilizing voice encoding techniques with error correction schemes This provides the user with enhanced range and audio quality all in a reduced bandwidth channel requirement It allows embedded signaling which can mix system information and data with digital voice to support a multitude of system features The SSE 5000 radio operates within the UHF range 450 to 488 MHz Major Assemblies The SSE 5000 radio includes the following major assemblies see Figure 2 1 VOCON Board contains a dual core processor which includes both the microcontroller unit MCU and a digital signal processor DSP core the processor s memory devices an audio an
