Explanation of test methods
*1: RF AGC delay point adjusting range:
V
RFdp
In the case of VIF gain reduction curve (figure 1), if the RF
AGC delay point adjustment DAC (0 A) goes 00 to 3F, the
internal comparison voltage changes by
V, and the delay point
adjustment range is determined.
*2: AFT discrimination sensitivity:
μ
AFT
Adjust DAC (0C-D7) and DAC (09) so that the AFT output voltage (V
30
) becomes approx. 4.5 V when f
P
=
38.9 MHz.
Measure
V

when f
P
=
38.9 MHz
±
25 kHz.
*3: Refer to "

Technical Information 4. 7) PAL/NTSC, SECAM interface".
*4: Black noise detection level:

*5: Inter modulation: IM
Apply the signal of f
