Scale Settings
Adjust the Y-axis scale to see the relevant portions of the data trace. The Y-axis is
divided into 10 graticules.
This setting can be changed at any time without affecting calibration accuracy.
How to set Scale
Press Scale / Amptd .
Then choose from the following methods:
1.

3. Set Scale, Reference Level, and Reference Position
Electrical Delay
Electrical delay is a mathematical function that simulates a variable length of
lossless transmission line. Use the electrical delay feature to compensate for the
linear phase shift through a device and view only the deviation from linear phase
of the device.
You can set the electrical delay independently for each measurement trace. To
apply an electrical delay to all measurement traces, use Port Extensions. Learn
how on page 30.
