7.4 Converting Input Values (Scaling Function)

1. For scaling, set the [Method] to [Ratio].
2. Point the flashing cursor to the conversion rate setting and select [dB Scal-
ing].
3. In the displayed entry field and physical quantity field, enter 40 dB and 60 dB,
respectively.
After entering the values, select [Confirm].
See: "7.1.3 Alphanumeric Input" (p.141)
The conversion rate for the entered dB value is entered. (The offset becomes 0.)

7.5 Variable Function (Setting the Waveform Display Freely)

Chapter 7 Utility Functions

The waveform height and display position can be arbitrarily set along the vertical axis (voltage axis).
The following two setting methods are available:
• Set the displayed amplitude per division (1div setting)
Set the amplitude to be displayed per vertical division and the zero position of
the waveform on the vertical axis (voltage axis).
• Set the Upper and Lower Limits (Upper-Lower setting)
The upper and lower limits on the vertical axis (voltage axis) can be set to dis-
play the waveform amplitude full-screen.
Settings for the Variable function can be made for each individual channel, using
the [Each Ch] sheet accessed from the Channel screen (p.156), or for all chan-
nels using the Display range window (p.157).

play Freely)
Precautions for using the Variable Function
• Verify that the vertical axis (voltage axis) range is set properly for the input sig-
nal.
• The vertical axis (voltage axis) range is unaffected by changes to the upper
and lower limits made by the Variable setting.
