How to Set the Vertical System

The

VERTICAL CONTROLS

includes three menu buttons such as

CH1

CH2

CH3

CH4

and

Math

and two knobs such as

Vertical Position

Vertical

Scale

Setting of CH1

– CH4

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

CH3

CH4

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

OFF

Close meascurr

10A/V
100.0 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

Full band
20M

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

1. 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
