3.5 Input Channel Setting

Chapter 3 Measurement Procedure

Set the analog channel and logic channel.

3.5 Input Channel Setting

See: "Displaying All Channels for Making the Variable Function Setting" (p.157)

Opening the Channel settings window

You can switch setting

screens by clicking a tab.

Click [DISP]→ [CH.SET] in the

right-click menu.

To hide waveform interpolation

Set the waveform display color in the channel setting window to Off.

See: "1. Waveform Display Color" (p.76)

To copy the settings of one channel to another

See: "7.8 Copying settings to other channels (calculation No.) (Copy func-

tion)" (p.160)

3.5 Input Channel Setting

Chapter 3 Measurement Procedure

The setting workflow for logic channels (standard LOGIC terminals LA - LB (MR8740), LA -LD

(MR8741), expansion LOGIC terminals L1A - L8D) is explained below.

• When input coupling is set to GND, the waveform will have no amplitude and

range setting is not possible.

• Due to the influence of filter attenuation, correct range setting may sometimes

not be possible.

• When making trigger settings, set the vertical axis (voltage axis) range first. If

the range is changed after specifying the trigger, the trigger setting may

change.

• When using the Variable function, set the vertical axis (voltage axis) range first.

If the range is changed after specifying the Variable setting, observation with

sufficient precision may not be possible.

• When using the Variable and Scaling functions together, make the Scaling set-

tings first. If Scaling settings are made after selecting the Variable function, the

intended display result may not be achieved.

1 Make screen display related settings

Setting logic recording width

See:

"1. Logic Width" (p.79)

2 Make display color and display position settings

Set waveform display position

Set waveform display color

See:

"2. Waveform Display Position" (p.79)

"3. Waveform Display Color" (p.79)

• Waveform display position can be specified in 1% increments.

• Not displayed for X-Y1 and X-Y4 screens.

• With MR8740, install the logic units on unit 1 to unit 8. Any logic units installed

on units 9 and after will be invalid.
