3.3.3 VERTICAL SYSTEM OPERATION
(1) VOLTS/DIV switch should be turned to the correct position following the input signal range.
Adjust position [16] to show the whole waveform within the available area. Adjust with VAR [17]
if necessarily, trimming ratio is 2.5:1.
(2) Input coupling options: “DC”is used for observing a signal with a direct current content such as
logic or static signals, “DC” must be used with low frequency. “AC”is used for observing the AC
component of signals. “
⊥
” (ground) is used to establish a trace at a zero volt reference.
(3) X-Y OPERATION: When [11] set at EXT/X, The oscilloscope is used for X-Y operation, at this
moment Input [19] is Y-axis with the same sensitivity, Input [13] as X-axis, [14] can be adjusted
continuously within 0.2V/DIV~0.5V/DIV.
3.3.4 TRIGGER SOURCE
In Fig 3-1, [12] provides 3 sources for selection, INT trigger, EXT trigger input from
[13], LINE input from power source.
3.3.5 HORIZONTAL SYSTEM OPERATION
(1)
Sweep setup : turn the sweep switch to the correct position according to the signal frequency
and adjust POSITION [7] to show the whole waveform within the available area. Adjust with
VAR [8] if necessarily, trimming ratio is 2.5:1.
(2)
There are 3 kinds of Trigger sources: [11] “AUTO”auto sweep, when a triggering signal is
applied, Level [9] will adjust to correct position. The screen showing a steady free run waveform
requires a frequency higher than 20Hz; [11] “NORM”while waiting for sweep with no trace.
When an input signal occurs the scope is triggered to sweep
(3)
and show the waveform . [10] “TV” used to determine TV signals.
(4)
SLOPE selection: Used to select whether the trigger signal crosses trigger level in a
positive or a negative-going direction.
(5)
Level setup : Use to adjust signal sweep on a level at a starting reference.
