returns the K-factor of 2-port measurement between port 1 and
port 2 of the ENA.
• When a scalar argument of the port number in the function is
out of range (i.e. mu1(1,3) for the 2-port ENA), the ENA
indicates an error message, “Equation runtime error” and
equation is not reflected on the trace.
Z0 means the system characteristic impedance (Z0) which can be
accessed under Cal.
• Although the port impedance for each port can be changed with
the port impedance conversion function by Fixture Simulator,
the change is not reflected on the computed trace by Equation
Editor.
Function Description
A(complex a, complex b,
complex c, complex d)
F
11
conversion = ((1+a)*(1-d) + b*c)/(2*b)
A(scalar i, scalar j) returns A(Sii, Sji, Sij, Sjj)
B(complex a, complex b,
complex c, complex d)
F
12
conversion = Z0*((1+a)*(1+d) - b*c)/(2*b)
B(scalar i, scalar j) returns B(Sii, Sji, Sij, Sjj)
C(complex a, complex b,
complex c, complex d)
F
21
conversion = (1/Z0)*((1-a)*(1-d) -
b*c)/(2*b)
C(scalar i, scalar j) returns C(Sii, Sji, Sij, Sjj)
D(complex a, complex b,
complex c, complex d)
F
22
conversion = ((1-a)*(1+d) + b*c)/(2*b)
D(scalar i, scalar j) returns D(Sii, Sji, Sij, Sjj)
H11(complex a, complex b,
complex c, complex d)
H
11
conversion = Z0*((1+a)*(1+d) - b*c)/((1-
a)*(1+d) + b*c)
H11(scalar i, scalar j) returns H11(Sii, Sji, Sij, Sjj)
H12(complex a, complex b,
complex c, complex d)
H
12
conversion = 2*c/((1-a)*(1+d) + b*c)
H12(scalar i, scalar j) returns H12(Sii, Sji, Sij, Sjj)
