An impedance Z is represented as Z = R + jX, the corresponding admittance as Y =
1/Z = G + jB. For X ≥ 0, we have an inductance L = X/ω, for X < 0 we have a capaci-
tance C = 1/(ωX), where ω denotes the stimulus frequency.

Marker Coupling
It connects the markers of a set of traces.
Marker coupling allows you to compare different measurement results (assigned to dif-
ferent traces) at the same stimulus value. It connects the markers of a set of traces.
Marker coupling can be enabled:
●
either for all traces in the active recall set that have the same stimulus variable as
the active trace
●
or for all traces in a channel
●
or for all traces in a diagram that have the same stimulus variable as the active
trace
When marker coupling is enabled, the same markers are activated for all related
traces: if a marker was active for some related trace, then it is activated for all related
traces.
