Notes
Note 1 Video S/N: VoS/N Input SG2 to VIF IN (Pin 20, 21) and measure the video out (TP1) noise in r.m.s. through a 5 MHz (-3 dB) L.P.F..
S/N = 20log
0.7 x Vodet (Vpp) (rms) NOISE
(dB)
Note 2 Video Band Width: BW 1. Measure the 1 MHz component level of Video output TP1 with a spectrum analyzer when SG3 (f2 = 44.75 MHz) is input to VIF IN (Pin 20, 21). At that time, measure the voltage at TP23, and them fix TP23 at that voltage. 2. Reduce f2 and measure the value of (f2-f1) when the (f2-f1) component level reaches -3 dB from the 1 MHz component level as shown below.
TP5
Note 3 Input Sensitivity: VIN MIN Input SG4 (Vi = 90 dBu) to VIF IN (Pin 20, 21) and then gradually reduce Vi and measure the input level when the 20 kHz component of Video output TP1 reaches -3 dB from Vo det level. Note 4 Maximum Allowable Input: VIN MAX 1. Input SG5 (Vi = 90 dBu) to VIF IN (Pin 20, 21), and measure the level of the 20 kHz component of Video output (TP1). 2. Gradually increase the Vi of SG and measure the input level when the output reaches -3 dB. Note 5 AGC Control Range: GR
GR = VinMAX - VinMIN (dB)
Note 6 Capture Range: CR-U 1. Increase the frequency of SG7 until the VCO is out of locked-oscillation. 2. And decrease the frequency of SG7 and measure the frequency fU when the VCO is locked.
CR - U = fU - 45.75 (MHz)
Note 7 Capture Range: CR-L 1. Decrease the frequency of SG7 until the VCO is out of locked-oscillation. 2. And increase the frequency of SG7 and measure the frequency fL when the VCO is locked.
CR - L = fU - 45.75 - fL (MHz)

M61111FP Note 8 Inter Modulation: IM 1. Input SG8 to VIF IN (Pin 20, 21), and measure video output TP1 with an oscilloscope. 2. Adjust AGC filter voltage TP23 so that the minimum DC level of the output waveform is Vsync. 3. At that time, measure TP1 with a spectrum analyzer. The inter modulation is defined as a difference between 0.92 MHz and 3.58 MHz frequency components. Note 9 RF AGC Delay Point (TV Mode): RFDP1 1. Input SG12 to VIF IN (Pin 20, 21) and gradually reduce level and then measure the input level when RF AGC output (TP17) reaches 1/2Vcc, as shown below. 2. At that time, the state of Pin 8 is DC open.

M61111FP Note 12 AFT sensitivity: , Maximum AFT Voltage: AFTH, Minimum AFT Voltage: AFTL 1. Input SG15 to VIF IN (Pin 20, 21) and set the frequency of SG15 so that the voltage of AFT output TP16 is 3 V. The frequency is named f(3). 2. Set the frequency of SG15 so that the AFT output voltage is 2 V. This frequency is named f(2). 3. In the graph shown below, maximum and minimum DC voltage are AFTH and AFTL, respectively.

M61111FP Note 15 Limiting Sensitivity: LIM 1. Input SG23 to LIM IN, and measure the 1 kHz component level of AF output TP11 with FLAT-r.m.s.. 2. Input SG24 to LIM IN, and measure the noise level of AF output TP11 with FLAT-r.m.s.. 3. The input limiting sensitivity is defined as the input level when the difference between each 1 kHz components of audio output (TP11) is 30 dB, as shown below.

1. Measure the frequency of output signal at AFT out (TP16) each when be selected US or JP by SW10. 2. Measured frequency's are defined FaftUS (US Mode), FaftJP (JP Mode). The VCO freerun frequency is calculated by following.
* US Mode FvcofUS = 52.915 (MHz) - 2 x FaftUS (MHz) - 45.75 (MHz) * JP Mode FvcofJP = 65.925 (MHz) - 2 x FaftJP (MHz) - 58.75 (MHz) [MHz] [MHz]
# Case of Fref frequency is 4.00 MHz, SW14 should be set up 2 (Pin 14 is connected 4.7 k to GND). Other Condition's are same as case of 3.58 MHz mode, and the VCO freerun frequency is calculated by following.
* US Mode FvcofUS = 52.952 (MHz) - 9 x FaftUS (MHz) - 45.75 (MHz) * JP Mode FvcofJP = 65.951 (MHz) - 9 x FaftJP (MHz) - 58.75 (MHz) [MHz] [MHz]

Recommendation
* By pass capacitance for Logic Vcc(Pin15) should be mounted close hard by Logic GND(Pin13) * In order to mitigate the surroundings lump by the VIF input, the balanced connection from a SAW filter
to the VIF input pin of 20,21 recommends a putter which serves as a 1t coil by Tip C or the jumper.
