Imbalance 1 / Imbalance 2
Imbalance 1
selects the balanced logical port i as the input, the single-ended logical
ports j and k as the output and calculates the imbalance parameter
Imb

Imbalance 2
selects the balanced logical port i as the output, the single-ended logical
ports j and k as the input and calculates the imbalance parameter

Create new trace and select trace name and measurement parameter:
CALCulate<Ch>:PARameter:SDEFine
"<Trace_Name>", "IMB<i>-<j><k>" |
5.9.9 Stability Tab
Selects one of the three two port stability factors K, μ
1
or μ
2
as measured quantities. A
typical application of stability factors is to assess the stability of an amplifier. Stability
factors cannot be calculated in balanced port configurations.
