Obtaining Measurements from the Eye Diagram
A range of signal parameters can be deduced from measurements made on the Eye Diagram.
The OTR 1001’s Auto Measure mode provides an automated read-out of signal amplitude, rise
time and fall time. These and other measurements can also be made using the pairs of voltage
and time cursors that can optionally be overlaid on the Eye Diagram both inside and outside of
Auto Measure mode.
Displaying the Cursors
Control Panel
Mouse & Keyboard
To select which cursors are displayed:
Tick the required cursors in the Properties control.
To toggle between displaying and hiding these cursors:
Either:
Select the
Cursors
option from the Button Bar (highlighted when the cursors are
displayed)
Or:
Tick/clear the
Show Cursors
option in the Properties control.
Moving the Cursors
Control Panel
Mouse & Keyboard
To move the cursors:
Use the HORIZ and VERT knobs.
The cursor moved is the one currently shown
in yellow. Pushing the knob switches over
control to the other cursor (bringing this cursor
back onto the screen if it is currently off-
screen). Pushing and holding the knob centres
the current cursor.
Drag with the mouse.
Signal Amplitude
Control Panel
Mouse & Keyboard
To measure the signal amplitude:
1.
Use the Properties control to display the Voltage Cursors.
2.
Position one Voltage cursor in line with the upper signal line and the other cursor in line with
the lower signal line.
3.
The Voltage Difference (dy) reading in the top right corner of the screen gives the signal
amplitude.
