Note:
The L02 FREQ ADJ and the 1st 10.7 MHZ IF ADJ and 2nd 10.7 MHz IF ADJ interact. See
paragraph 5.3.6, Distortion Alignment, for additional information.
70 MHz BPF ADJ
Bandpass Filter Adjustments. The alignment of the 70 MHz
(C41,C44,C47)
bandpass filter can be checked indirectly by verifying the
receiver noise performance to within 20
μ
V of the value specified on
the final test data sheet included in this manual. (See paragraph
5.3.2, Receiver Sensitivity).
MUTE THRESHOLD (R18)
Mute Threshold Adjust. Adjusts the mute logic threshold; threshold =
20
μ
V input signal.
BB LVL ADJ (R19)
Baseband Level Adjust. Adjust the output of the baseband including
the composite and MUX levels.
±50 kHz deviation = 3.5 V
p-p
.
BB LVL (TP2)
Baseband Level Test Point. An AC test point used to monitor the
output level of the baseband processor.
±50 kHz deviation = 3.5 V
p-p
.
DEMOD BALANCE (TP1)
Demod Balance Level. Is an indication of quadrature coil balance
(minimum distortion) and/or demodulator free drift
(0 ± 1 VDC).
5.4.8
Double Converter/LO3 (PCL6030/6060)
70 MHz BPF ADJ
Bandpass Filter Adjustments. The alignment of the 70 MHz
(C40,C43,C46,C49)
bandpass filter can be checked indirectly by verifying the
receiver noise performance to within 20
μ
V of the value specified on
the final test data sheet included in this manual. (See paragraph
5.3.2, STL Receiver Sensitivity.
1ST IF FLTR SELECT (E2,E3) Selects proper filter for intended system application.
1ST 10.7 MHz IF ADJ WB (C14)Wideband IF Filter Adjust. Determines selectivity and distortion
specifications.
1ST 10.7 MHz IF ADJ NB (C15) Narrowband IF Filter Adjust. Determines selectivity and distortion
specifications.
1ST 10.7 MHz IF ADJ MONO Mono IF Filter Adjust Determines selectivity and distortion
(C13) specifications.
2ND IF FLTR SELECT (E4,E5) Selects proper filter for intended system application.
2ND 10.7 MHz IF ADJ COMP Composite IF Filter Adjust. Determines selectivity and distortion (C21)
specifications.
2ND 10.7 MHz IF ADJ MONO Mono IF Filter Adjust. Determines selectivity and distortion (C22)
specifications.
LO3 OUT LVL (FL6)
LO3 Output Level. DC voltage sample of 3rd LO at 13.7 MHz (0.3–1.2
VDC).
5.4.9
Preamp/1st Mixer (950 MHz, PCL6060)
RF ATTEN ADJ (R13)
Sets the value of front end attenuation (up to 15 dB).
