Vertical controls

The vertical controls select the displayed signals and control the amplitude

characteristics.

(11) CH1—Pushbutton

(12) CH2—Pushbutton

Pressing briefly the CH1 (CH2) button to set the channel 1 (channel 2) of

the instrument on, the deflection coefficient will be displayed in the readout

indicating the current conditions.

(13) CH1 POSITION—Control knob

The vertical trace position of channel 1 can be set with the control knob. When

X-Y operation in the Storage mode, CH1 POSITION control knob is used for

the X deflection.

(14) CH2 POSITION—Control knob

The vertical trace position of channel 2 can be set with the control knob.

In X-Y operation, CH2 POSITION control knob is used for the Y

deflection.

(15) ALT/CHOP

In the REAL TIME mode, the pushbutton has two functions, which are

required and available only when both channels are active.

ALT—Displays in the readout, indicates alternate channel switching. After

each time base sweeps the instrument internally, switches over from channel

1 and channel 2 and vice versa.

CHOP—Indicates chopper

The channel switching occurs constantly between channel 1 and channel 2

during each sweep.

In the STORAGE mode, ALT or CHOP mode is automatically selected by

TIME/DIV range. The ALT mode is established for the sweep range of

0.5ms/DIV or faster. The CHOP mode is established for the sweep range of

1ms/DIV or slower.

(16) ADD-INV—Pushbutton with double functions.

ADD– Displays the “+” symbol in the readout, indicates additional mode.

Whether the algebraic sum (addition) or the difference (subtraction) of both

input signals is displayed, depends on the phase relationship and the INV

setting. As a result, both signals are displayed as one signal. For correct

measurements, the deflection coefficients for both channels must be equal.

INV—Pressing and holding the pushbutton to set the channel 2 invert

function on or off. The invert on condition is indicated by the “ ” symbol

in the readout. The invert function causes the signal display of channel 2 to

be inverted by 180

o

.

(17) CH1 VOLTS/DIV

(18) CH2 VOLTS/DIV– Control knob for channel 1/channel 2 has double functions.

Turning the knob clockwise to increase the sensitivity in 1-2-5 sequence and

turning it in the opposite direction (CCW) to decrease. The available range is

from 1mV/DIV up to 20V/DIV. The knob is automatically switched inactive if

the related channel is switched off.
