changes the Volts/Div scale in small steps between the coarse settings. Increase in the

clockwise, reduce in the anticlockwise.

2.6.3 Math Functions

Math shows the results after +,-,*, / and FFT operation of the CH1,CH2,CH3 and CH4.

Press the MATH button to display the waveform math operations. Press the MATH

button again to remove the math waveform display.

Table 2-6 MATH function menu:

Function

Setting Introduction

Operation

+、-、*、/、FFT

Math operate between signal

source CHX and CHY.

CHX

Invert

off

Invert the CHX waveform.

Turn off CHX Invert function.

CHY

Invert

off

Invert the CHY waveform.

Turn off CHY Invert function.

Table 2-7 MATH function instruction

Operation

Setting Introduction

＋

CHX+CHY CHX waveform adds CHY

waveform.

CHX-CHY The channel Y waveform is

subtracted from the channel X

waveform.

－

CHY-CHX The channel X waveform is

subtracted from the channel Y

waveform.

* CHX*CHY Source X multiply source Y.

CHX/CHY Source X divides Source Y. /

CHY/CHX Source Ydivides Source X.

FFT Fast Fourier Transform.

CH1 waveform add CH2waveform, see picture 2-18:

Note:X,Y represent CH1,CH2,CH3 and CH4 respectively, but X and Y can’t represent the

same signal source.
