6.1 Reading Measurement Values (Using the A/B Cursors)
120
• Time difference, frequency and potential difference (and when scaling is enabled, scaling values)
can be read as numerical values using the A/B cursors on the Waveform screen. The cursors also
allow specifying the calculation and X-Y synthesis range.
• When displaying the X-Y waveform, the A/B cursors can be used to read the measurement val-
ues. Also with a split screen, A/B cursors can be used separately in the graphs to read the poten-
tial difference between the A and B points.

B Cursors)
A/B Cursor Settings
To open the screen: Right-click and select [DISP] Waveform screen Left-click [AB CSR] A/B cursors
settings window
1
Left-click the [AB CSR] icon.
Left-click the [AB CSR] icon on the top right of
the Waveform screen.
2
Select the Cursor Type.
Select
Move the flashing cursor to the [A/B Cursosrs]
item and select it.
3
Select the movement target for the A/B
cursors
Select
Move the flashing cursor to the [Kind] item and
select it.
4
Select the measurement target channel
([Subject CH]) for A and B
Select
Move the flashing cursor to the [A] or [B] item
and select it.
5
Move the A/B cursors
If you click while the mouse cursor is in the
Waveform screen, the A/B cursors move to that
position. Furthermore, you can also move the A
or B cursor by dragging the A or B cursor mark
on the Waveform screen while holding down the
left button of the mouse.
Off A/B cursors are not used.
div
Move in horizontal axis (time axis) direction (X
axis for X-Y synthesis)
Range
Move in vertical axis (voltage axis) direction (Y
axis for X-Y synthesis)
Trace
Trace waveform data.
A Use only cursor A.
A-b
Use A/B cursors but move only cursor A.
a-B
Use A/B cursors but move only cursor B.
A&B
Move both cursor A and cursor B together.
ALL Shows measurement values for all channels.
(When cursor type is [Trace] or [Range])
Ch1 to
Ch16
Show measurement values in selected channels
out of Ch1 - Ch16 (for 1, 2, 4, 8, 16 screens).
Gr1 to
Gr8
Specify X-Y synthesis for Gr1 to Gr8 (for X-Y
screen)

When there is data on which waveform calculation
has been performed, the cursor target is switched
by analog channel and waveform calculation data.

If numerical values are hard to read
Right-click and select [DISP] to enable display selection. You can display the wave-
form and numerical values separately.
See: "6.7.3 Switching the Waveform Display Width" (p.135)
To view the waveform before or after the A/B cursors when these are off the
screen
When using the A/B cursors, the waveform at an off-screen cursor location can be dis-
played using the Jump function.
See: "6.3.3 Moving the Position" (p.126)
If A/B cursors are activated but do not show up on screen
The position of the A/B cursors can be checked on the scroll bar.(p.125)
If the cursor type is [div] or [Trace] cursors, cursor measurements can be made even
if the A or B cursor is off-screen.

• When Using External Sampling: Value t is the number of samples.
• The data measured with MR8990 Digital Voltmeter Unit is updated at each of
the two movement points of the A and B cursors.
• When the voltage range is changed during measurement by the recorder func-
tion: Trace measurement values are acquired at the range settings when mea-
surement was stopped.
