Command Syntax

:GRAPh:T:PERcentN:X:DCONstant <dielectric constant>

<dielectric constant> is a double ranging from 1.0 to 100.

Where N specifies one of four {1:4} waveform content windows.

Query Syntax

:GRAPh:T:PERcentN:X:DCONstant?

Description

For the waveforms in the selected Time-% waveform content window, specifies the Dielectric Constant (ε_r), also known as Relative Permittivity, of the DUT path. This discribes the velocity of propagation through the DUT path which enables accurate scaling of the graph's X-axis when distance (meters) is selected using the :UNITs sibling command. The default setting for the X-axis is time (seconds). If you know the Velocity Factor for the DUT path, you can accomplish the same task using the :VFACtor command.
