Reading Measured Values (Trace Cursors, Horizontal cursor)
2.1 Reading Measured Values (Trace Cursors,
Horizontal cursor)
You can read measured values (scaled values when the scaling is used) using cursors on the
waveform screen.
The instrument can simultaneously display up to eight cursors, which contains the trace cursors
and horizontal cursors.
You can read differences in measured values and time values between any two cursors you choose
from among all cursors.
The display way of the cursor values varies depending on the chosen cursor type.
Cursor type Cursor value
Trace cursor
When you select trace cursor A and trace cursor B
Time: Time between the trigger point or recording starting point and the trace
cursor
Measured value: The measured value at the point where a waveform crosses a
trace cursor
B-A: Difference in measured values between trace cursor B and trace cursor A
B − A (Time lag)
B − A (Difference between measured values)
A B
Horizontal cursor
When you choose horizontal cursor A and horizontal cursor B
Measured value: The vertical axis value at a horizontal cursor
B − A: Difference in measured value along with vertical value between horizontal
cursor A and horizontal cursor B
A
B
B − A (Difference between measured values)
When the external sampling is used, the time is represented in the number of samples.

Choose two cursors to be used from among [Trace cursor A] through [Trace cursor H].
You can simultaneously use up to eight cursors.
The chosen trace cursors are displayed on the waveform screen.
Drag the trace cursors on the waveform screen to move them.

Click a trace cursor of which you want to display the value.
You can choose up to two cursors from among trace cursor A ([Trace cursor A]) and trace cursor H ([Trace
cursor H]).
