Hints
1. FAST SWEEP is used for systems that do not have scrambled channels. However, the fast
sweep is useful in making rough measurements and adjustments on systems with scrambled
channels. More accurate results can be obtained in a following test with the slow sweep.
2. SLOW SWEEP allows the analyzer to measure the vertical sync pulse level when the horizontal
sync pulse has been suppressed. An H-second sweep normally is optimum for this measurement,
but for analyzer spans greater than 300 MHz, a slower sweep time may be necessary to reduce
trace fluctuations caused by the scrambling.
