FDL-PT222 SECTION 3 CIRCUIT ADJUSTMENTS 3-1.A BOARD ADJUSTMENT [+4.5V ALIGNMENT (RV601)] [VIF.AFT COARSE ADJUSTMNT (T201, T202)] [SETUP] 1. Set S601 on the A board to VHF position. 2. Apply no signal to JL18 (RF). 3. Connect a 1 kΩ resistor between JL77 (+4.5V) and JL28 (RF AGC). 4. Apply a sweep signal across JL26 (IF) and JL27(IF GND). (Fig. 3-1) Using a digital voltmeter measuring the voltage between JL32 (+4.5V) and JL33 (GND). Adjust RV601 to obtain the value shown below. Standard Value = 4.45V± 0.
FDL-PT222 [AFT FINE ADJUSTMENT(T201)] 3-3.B BOARD ADJUSTMENT 1. Connect a 1 kilohm resistor between JL77 (+4.5V) and JL28 (RF AGC). Note : Perform this adjustment as the last step in the process since drift may occur due to aging. 2. Switch the sweep signal to CW. fo= 45.75 MHz±5 kHz, -30±5dBm Apply the above signal between JL26 (IF) and JL27 (IF GND) and then make a fine adjustment of T201 so that the level between JL31 (AFT) and JL30 (D.GND) reaches2.2V±0.4VDC. 3.
