ADJUSTMENT 3-1. Frequency synthesizer - After connecting the RF power meter and dummy load (50 ohm), join the antenna connector of HP8920 with above equipment. - Check the voltage between TP and GND in digital Voltage meter. - The set low channel(CH1, 151.820Mhz) of HP8920 the lowest frequency. - After pressed PTT key of HP8920, check if the lowest frequency of Tx channel to DC 1.2V in the voltage of test point (VT) - After releasing the PTT key of HP8920, check if the highest frequency (CH5,154.600Mhz) of Rx channel is within DC 1.2V in the voltage of test point (VT). 3-2. Transmitter - Connect the RADIO and measure equipment according to block diagram below. - load) after power on. - Connection method - The Conform of Rx sensitivity 1) Set SSG to 1channel(151.820Mhz) frequency. 2) Adjust modulation frequency, 1khz to modulation degree, 1.5khz. 3) After adjusting the frequency of SSG to channel frequency, RF level sets to –47dBm. - The Conform of Squelch sensitivity 1) Set the standard channel (CH1, 151.820Mhz) 2) In squelch mode, SQ variable resister VR101 must be turned counterclockwise. 3) After adjusting SSG to channel frequency, the RF level of SSG is set On SINAD 12~0dB. 3-5. Receiver Test - Rx sensitivity test SSG should be adjusted to 12dB of SINAD point needle seeing wave of Oscilloscope as SSG sets in 1khz frequency deviation. At this time, normal RF level is –122~-124dBm. - Audio Distortion Test 1) SSG should be adjusted like way of point “Rx sensitivity test” and RF level sets to –47dBm. 2) Adjust to 0.7Vrms (8 load) seeing Audio wave. 3) Read the needle of Distortion Meter (Normal condition would be less then 5% Distortion) - Squelch Test After RF level of SSG should be set to the least
