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
= –(S
ca
– S
da
)/(S
cb
– S
db
)
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
= –(S
ac
– S
ad
)/(S
bc
– S

)
Remote command:

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.
