Realistic PRO-2021 - VHF-HI Band RF AMP Alignment; UHF Band RF AMP Alignment

VHF-HI BAND
138 MHz (CH1), 154 MHz (CH2), 174 MHz (CH3)
Connect instruments: Same connection as VHF Lo band except Sweep Generator frequency,
Step 1:
change to 138 MHz to 174 MHz.
Step 2: Program 138 MHz (CH1), 154 MHz (CH2), 174 MHz (СНЗ).
Step 3: Select Channel 2 (154 MHz) and adjust T2 and T5 for maximum RF waveform.
Step 4: Check Channels 1 through 3 for maximum RF waveform. Slight deviation as shown below is
acceptable.
