Variable Input Sensitivity The variable input sensitivity allows you to adjust the input A sensitivity continuously, for example to set the amplitude of a reference signal to exactly 6 divisions. The input sensitivity of a range can be increased up to 2.5 times, for example between 10 mV/div and 4 mV/div in the 10 mV/div range. To use the variable input sensitivity, do the following: 1 Apply the input signal 2 Perform an Auto Set (AUTO must appear at the top of the screen) An Auto Set will turn off the variable input sensitivity. You can now select the required input range. Keep in mind that the sensitivity will increase when you start adjusting the variable sensitivity (the displayed trace amplitude will increase). 3 Display the INPUT A key labels. 1 Using The Scope Acquiring Waveforms 4 Open the Input A Options... menu. 5 Select and accept Variable. 6 Exit the menu.

Variable Input Sensitivity
The variable input sensitivity allows you to adjust the input
A sensitivity continuously, for example to set the amplitude
of a reference signal to exactly 6 divisions.
The input sensitivity of a range can be increased up to 2.5
times, for example between 10 mV/div and 4 mV/div in the
10 mV/div range.
To use the variable input sensitivity, do the following:
1
Apply the input signal
2
Perform an Auto Set (AUTO must
appear at the top of the screen)
An Auto Set will turn off the variable input sensitivity.
You
can now select the required input range.
Keep in mind
that the sensitivity will increase when you start adjusting
the variable sensitivity (the displayed trace amplitude will
increase).
3
Display the
INPUT A
key labels.
4
Open the
Input A Options...
menu.
5
Select and accept
Variable
.
6
Exit the menu.
At the bottom left of the screen the text
A
Var is
displayed.
Selecting Variable will turn off cursors and automatic input
ranging.
7
Press mV to increase the
sensitivity, press V to decrease
the sensitivity.
