When the setting (voltage) value is out of the changing portion of the

observation waveform, the synchronization sweep stops.

TRG LED

The TRG LED is lit if the triggering conditions are met. Whether the LED

flashes or is lit constantly depends on the frequency of the trigger signal.

(36) HOLD-OFF—Control knob (REAL TIME mode only)

Used when the signal waveform is complex and stable triggering cannot be

attained with the TRIGGER LEVEL(35) knob alone, rotate this control knob

to adjust hold-off time(trigger inhibit period beyond sweep duration). When

control is rotated fully clockwise, the hold-off period is at MINimum

(normal). The hold-off period increases progressively with counterclockwise

rotation.

(37) TRIG EXT—This BNC socket is the external trigger signal input.

Pressing the TRIG. SOURCE (31) pushbutton until the information of “EXT,

slope, coupling” is shown up in the readout switches the input on.

The outer (ground) connection is galvanically connected to the instrument

ground and consequently to the safety earth contact of the line/mains plug.

The maximum input voltages of the input terminal are shown in the section

of 3-6. “Withstanding voltage of Input terminals”. Do not apply voltage

higher than the limit.

Storage Control

The Storage Control select the digital storage function.

(38) STORAGE/REAL TIME mode

Switch the REAL TIME mode to (digital) STORAGE mode by pressing the

button. In this case, all the switches from (39) to (42) are valid.

When the switch is pressed again in the STORAGE mode, the REAL TIME

mode is established again. In the STORAGE mode, the RUN LED blinks in

synchronism with sampling.

(39) MENU

Press the pushbutton to change the acquisition mode, the smoothing ON or

OFF, the interpolation method and the selection of SAVE/RECALL waveform

memory. Each pressing changes the setting mode and the present setting mode

is displayed at the top right on the CRT. The settings in each mode are

changed by the VARIABLE (9) control knob. Please refer to section 5-7 for

details.

(40) RUN/STOP—Pushbutton and indicator LED

Pressing this pushbutton to stop sampling, resulting in the hold state, and the

RUN LED is off. The current setting is indicated by the readout (“STOP”).

Further pressing the pushbutton to release hold state and start sampling states.
