2.2.4 Single-trace mode

Single-trace mode using the single time base

and internal triggering is a frequently used op-

erating mode. Use this mode if you only want to

observe one signal.

Because this oscilloscope is a dual-trace unit,

there are two particular ways of obtaining

single-trace operation.

2. Use the POSITION knob (16) or (17) to bring

the trace into the centre of the screen

3. Connect the signal lead carrying the signal to

be fed in to the channel you previously selec-

ted. Set the VOLTS/DIV switch so that the

signal amplitude takes up the entire height of

the screen.

4) To stop the signal moving, adjust the trigger

level knob (29) if necessary.

a) If you want to read off the frequency on a

frequency counter at the same time as ob-

serving the signal, select channel 1 (CH 1) as

the signal feed. The signal applied to channel

1 can be picked off on a BNC socket at the rear

of the oscilloscope for further use, but at

reduced amplitude.

b) Channel 2 (CH 2) offers the facility to invert

the signal by means of the POSITION knob

(17), i.e. the signal is rotated through 180°.

Basic settings for single trace mode

1. Set up the oscilloscope for single trace mode as described below. Make sure that the trigger

SOURCE switch (27) and the channel that is used actually match (signal feed in channel 1 => switch

(27) set to CH 1)

Power switch (1) : set to ON

AC/GND/DC switch (10) or (11) : set tof AC

Vertical POSITION (16) or (17) : middle position and depressed

VARIABLE (14) or (15) : right-hand stop and depressed

Vertical MODE switch (18) : set to CH 1 or CH 2

Trigger MODE switch (26) : set to AUTO

Trigger SOURCE switch (24) : set to CH 1 or CH 2

Trigger LEVEL (29) : set to middle position

HOLDOFF knob (28) : set to NORM position = left-hand stop

Warning!

Do not exceed the maximum input values.

Never connect voltages in excess of 300 V DC or

212 V AC rms.
