Horizontal distance (div) × sensitivity (Time/div)

Rise Time = -----------------------------------------------------------

Horizontal factor

For the example shown in Fig.4-7, the horizontal distance from 10% to 90% is 2.4 divisions, the

sweep TIME/DIV setting is 1µS/DIV, factor x 1. The rise time is calculated as follows:

1µS/DIV × 2.4DIV

Rise Time = ------------------------------ = 2.4µS

4.4 TV Signals measurement

Steps :

(1) Connect TV signals to INPUT jack [19]

(2) Set Trigger method to “TV” [10], Sweep switch turn to 2mS/Div.

(3) Observe the screen, it should be negative synchronize pulse wave.

(4) Adjust VOLTS/DIV and VAR to obtain proper range.

4.5 X– Y mode applications

There are some cases which X axis requires control from external signals, e.g. external

connection of sweep signals, signals of Lissajous patterns or other equipment’s display setup.

X-Y mode operation is turn [11] to EXT/X, input signals through [13], sensitivity to be adjusted

directly with [14], then input Y signal through [19].
