Port
Physical test port of the analyzer. You can define independent offset parameters for all
ports.

Delay / Electrical Length / Mechanical Length
Defines the length offset at the selected port as a delay, an electrical length, or a mechan-
ical length. The three quantities are related by:

Note:
The entered parameters must correspond the actual (one-way) length of the trans-
mission line. To account for the propagation in both directions, the phase shift of a reflec-
tion parameter due to a given length offset is twice the phase shift of a transmission
parameter. For a numeric example see

Remote command:
Permittivity / Velocity Factor
Defines the permittivity (ε
r
) and velocity factor of the dielectic in the transmission line
between the reference plane and the DUT. The velocity factor is 1/sqrt(ε
r
) and is a mea-
sure for the velocity of light in a dielectric with permittivity ε
r
relative to the velocity of light
in the vacuum (velocity factor < 1). Permittivity and velocity factor are coupled parame-
ters.

Remote command:
Adjust Time Gate
Activates the operating mode where the time gate is moved in the opposite direction when
the "Delay" setting (or any other length offset parameter) is changed. The button is avail-
able if a time gate is active ("TRACE > TRACE CONFIG > Time Gate > Time Gate:
On"). In time domain, a positive delay shifts the time gate to the left, a negative delay
shifts it to the right.
