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 following imbalance parameter:
Imb
jk-i
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 following imbalance parameter:
Imb
i-jk
Remote command:
CALCulate<Ch>:PARameter:MEASure "<Trace_Name>", "IMB<i>-<j><k>"
| "IMB<j><k>-<i>"
CALCulate<Ch>:PARameter:SDEFine "<Trace_Name>", "IMB<i>-<j><k>"
| "IMB<j><k>-<i>"
5.2.9 Stability tab
Selects one of the three two port stability factors K, μ
typical application of stability factors is to assess the stability of an amplifier. Stability
factors cannot be calculated in balanced port configurations.
