How to Set the Vertical System

The

VERTICAL CONTROLS

includes three menu buttons such as

CH1

CH2

and

Math

and four knobs such as

Vertical Position

Vertical Scale

for each channel.

Setting of CH1 and CH2

Each channel has an independent vertical menu and each item is set respectively
based on the channel.

To turn waveforms on or off (channel, math)

Pushing the

CH1

CH2

, or

Math

buttons have the following effect:

• If the waveform is off, the waveform is turned on and its menu is displayed.

• If the waveform is on and its menu is not displayed, its menu will be displayed.

• If the waveform is on and its menu is displayed, the waveform is turned off and its

menu goes away.

The description of the Channel Menu is shown as the following list:

Description

Coupling

DC
AC
Ground

Pass both AC and DC components of the input signal.
Block the DC component of the input signal.
Disconnect the input signal.

Inverted

ON
OFF

Display inverted waveform.
Display original waveform.

Probe

1X
10X
100X
1000X

Match this to the probe attenuation factor to have an
accurate reading of vertical scale.

MeasCurr

Yes
No

If you are measuring current by probing the voltage
drop across a resistor, choose

Yes

A/V
or mA/V

V/A
or mV/A

Turn the

knob to set the Amps/Volts ratio. The

range is 100 mA/V - 1 KA/V.
Amps/Volts ratio

= 1/Resistor value

Volts/Amp ratio is automatically calculated.

Limit (only
for

SDS1102

)

Full band
20M

Get full bandwidth.
Limit the channel bandwidth to 20MHz to reduce
display noise.

To set channel coupling

Taking the Channel 1 for example, the measured signal is a square wave signal
containing the direct current bias. The operation steps are shown as below:

(1)

Push the

CH1

button to show the CH1 SETUP menu.
