Variables are:
• PI 3.1415926...
• Z1 Port 1 Reference Impedance
• Z2 Port 2 Reference Impedance
• Z3 Port 3 Reference Impedance
• Z4 Port 4 Reference Impedance
Operators include:
• addition (+)
• subtraction (−)
• multiplication (*)
• division (/)
• exponentiation (^)
Functions include:
ABS X ( )
= A
CONJ X ( )
= A JB
REAL X ( )
= A
IMAG X ( )
= B
ARG X ( )
= TAN
where X is a complex number, A = Re(X), and B=Im(X).
Expressions can be prioritized by using parentheses. Operator precedence follows the order
parentheses ( ), functions (ABS, CONJ, REAL, IMAG, ARG), exponentiation, multiplication
and division, addition and subtraction. There must be one more operand than operators.
Important: Negative constants must be enclosed in parentheses, even when the negative
constants are inside function parentheses.
To offset the phase of an operand by 180º, multiply by (−1). To offset the phase by 90º, multiply
by (−1)^0.5.
