36、t which the signal level becomes 1/10 (-20 dB) of the level of 1 MHz by oscilloscope with one decimal unit of MHz. Calculate the horizontal resolution, Rh, by the following formula. Rh= (3/4) 2 (1 ) (f0 106/fH) 80 f0(TV lines) where fHis the horizontal line frequency (in Hz); is the blanking duratio

37、n rate of the horizontal line (0,17); f0is the frequency which signal level is becoming to 1/10 (-20 dB ) of the level of 1 MHz (in MHz).

38、is reported to 540 TV lines. NOTE 2 In the case where the envelope of the sweep signal appears double, the lower level should be read as the measuring value. In the case where the envelope has a ripple, the dip-point level is read as the measuring value. Test disc EUT Oscilloscope 75 Output IEC 2057
