Velocity factor is the ratio of the velocity of wave propagation in a coaxial cable
to the velocity of wave propagation in free space. This velocity depends on the
relative permittivity of the cable dielectric (er).
Velocity factor = 1/sqrt(er)
VF = 0.66 corresponds to wave propagation through a polyethylene dielectric.
VF = 1.0 (default setting) corresponds to wave propagation through free space
(a vacuum).
How to set Velocity Factor
— Press Meas Setup 4 .
— Then Port Extensions
— Then Velocity Factor
— Then enter a value between 0.1 and 1 using the numeric keypad, then press
Enter .
You can also set Velocity Factor by pressing Meas Setup 4 then Calibration
(settings) .
Big Marker Display States (A and B)
This feature, available ONLY in NA Mode, allows you to view up to three Big or
Super Big marker readouts. This is done by using up to two different display
states called A and B. Each display state is comprised of the settings listed
below. When the Big Readout setting is toggled through A and B, these display
states are recalled.
How to create Big Marker Display States
To have big readouts, markers MUST be created using the following procedure.
If you have already set up your display and do not want to lose it, then save the
current state to a state file. Learn how in “State Files” on page 676 . The
following procedure will overwrite your display state.
— Press Mkr ->/ Tools
— Then Big Readout
— A or B - The A or B display state is recalled. If none have been defined,
then the default display state is recalled.
— OFF - The B display state is visible but without the Big Marker
Readout.
— With A or B selected, then press Edit Big Marker (A or B)
— Then edit the following display state settings:
—
Num Traces – Choose the Multi-Trace configuration x1, x2, or x3. Only
Overlayed configurations are allowed. Learn more in “Multi-Trace
Configurations” on page 91 .
